High Magnification Photography - Extreme Macro with Microscope Objectives
Vložit
- čas přidán 3. 07. 2024
- This is a quick introduction to an upcoming series of videos all about high-magnification macro photography using microscope objectives instead of camera or enlarger lenses. I try to demystify what can be a rather intimidating area of the macro world.
For those of you interested in learning more about the issues touched on in this video, I highly recommend you visit the following website. All three are jam-packed with useful information and will serve as reliable resources for extreme macro photography:
1) Extreme-Macro.co.uk
2) Photomacrography.net
3) closeuphotography.com
** these links have been updated - January 2022**
If you want to give this fascinating macro technique a try, here is the recommended equipment that I will be using in the next video:
1) The microscope objective (AmScope Plan 4/0.10 160/0.17) which you can find right here (NOT an affiliate link)
amzn.to/3g4Zf64
2) An adapter for connecting the objective to M42 extension tubes (RMS to M42 adapter) - you can find these on eBay, B&H, and Amazon. The Amazon link is:
amzn.to/3AxvZhU
3) Extension tubes - I recommend using M42 tubes. They come in a variety of lengths and screw together to make one long tube. For this setup there are no glass elements to worry about so the length of you tube needs to be 160mm MINUS the flange distance of your particular camera. For Nikon full frame F-mount cameras that distance is 46.5mm, meaning I will be using a extension tubes totaling 113.5mm in length. Because this is not a nice round number (and this distance is very important!) I will be using a short helicoid (M42 size) which will allow me to make fine adjustments to the overall length of the extension tubes. eBay, Amazon, and all photography shops should have inexpensive M42 helicoids available. M42 extension tubes can be purchased from the usual outlets, but the cheapest I could find are on Amazon.…

4) The last thing you will need is an adapter to connect the screw-in M42 extension tube to your camera. This is the Nikon one from Amazon…

I'm delighted to have found your CZcams channel. Thank you for the insightful videos and the wealth of knowledge you share with us. 😊🙋🏼♂️
So happy I found your video. I have an older microscope that was given to me so I could give her to my daughter for school. She used it only once. Good thing it was free. It's in great shape and has a 10x, 40x and 100x objective. Can't wait to start playing with these. Thanks!!
Just came across your feed, Allan. So many even on youtube won't share where they've learned things, so I really appreciate that you have here!
Great intro to the subject. Thanks
Great video looking forward to the next.
Excellent video. Easy to understand. I have my parts ordered cannot wait for the next video. Thank you.
Finally someone find time about the theme. BRAVO.
Thanks Kristijan!
Fantastic information for us newbies! Thank you! 👍👍👍
Brilliant, thank you.
Great information, Allan! Thank you.
Cheers, Carl! More on the way.
Looking forward to the next in the series!
Excellent! Won't be long!
Sweet as video, I'm sold
Thank you for this!!!!!
you are the best in this field >>
most beneficial video, thanks a lot
Interesting topic, Alan. I am looking forward to seeing the setup in the next video. I am also looking forward to some more compositing. Those are always fun.
Couldn't agree more, Stephen!
very informative video. thanks for sharing your knowledge
Excellently explained! Very much looking forward to your next videos on this subject. I'm in the planning phase to but a proper rail and an high end objective, so this series of videos will be very interesting for me.
Thank you, Torbjørn! It is going to be fun!
I used to be part of photomacrography.net many years ago which is where I first learned about image stacking and using microscope objectives in photography. I haven’t been back in a very long time. It’s probably time to start back again. Thanks for the video.
I’m excited for this series! I’ve searched around before but could never find anything easy to digest for beginners and just gave up.
Hi John. Good to hear... I wasn't able to find much that bridges the gap into this exciting area of macro. I hope this series takes care of that.
Thank you Allan! Amazingly detailed overview. I would love to see some of your macro shots edited in here and there to remind us what we are after. God bless.
Great video. Send my love to Alison
She will need it since she went hungry
Looking forward to this Series Allan
Thanks Graeme - this is what I love to do and I think it is going to be a fun series. We have a great deal to dig into!
Great video, just remembered a box of B&L microscope objectives from 5x to 40x with a super heavy microscope from an auction years ago
You are the best. Thank you from the bolivian botanists!
Thanks, Gustavo!
teacher of teachers ))very detailed thank you
Thank you!
Thanks Allan!! I am looking forward to more on objective macro photography. I have been interested in this for quite a while now. This is a great excuse to get off of my backside and do it.
Thanks David. I'm really excited about this series too. This is what I do when I'm not working. It is a really magical area of photography.
@@AllanWallsPhotography The third link you posted had one to many "p"s in it. Should be "closeuphotography.com" Now you know folks are taking advantage of what you share!!!
@@davetyler8214 Oh dear... I am a horrible typist. Thanks, I'll fix it now. And it is a really tremendous site. So full of great information!
Hi Allan! It is a pleasure to see you again, my eye has been improving every week and I am here again catching up with your magnificent videos. This world of extreme macro photography is very interesting. I started doing some tests before my surgery with two finite lenses, 4X and 10X, a Pentacon bellows and extension tubes, the results are incredible, I did two tests, one with the eye of a dragonfly and the other with the wing of a butterfly . I look forward to the next videos of this new series. Allan thank you very much for all the time you invest in preparing these videos and what I have learned from the macro photography is we should have fun and spend pleasant moments doing this type of photos and not suffer for not getting any results, all this is a constant practice of try and failure. Kind regards from Mexico.
Enrique, my friend! Good to hear from you! I'm glad to hear your recovering is progressing. I didn't realize you were into high-magnification work.Good to hear! I hope you find the upcoming videos helpful. Take care!
Allan Walls Photography Allan thank you very much for your kindly words, see you soon!!
Teşekkürler.
Allan, any plans on making an additional video on using the 4x and setting it up? Thanks again for all the great content.
I have the same question. I would like to get all the details from set up to take the shots.
awesome :) i found a wooden box on the side of the road, in it was a microscope with 5 lenses, already had an nikon and a bellows :) gonna try this at the studio next week
so? Did you do it? How did it go?
Allan, great videos and I appreciate you not rushing through. I missed one thing which is to get the 160mm once you take off the Flange distance where on the Objective lens does the required distance end? Is it at the position of the objective where it screw in or at the lens end? I have ordered all the parts for my Canon setup. Also, when you are using the Helix do you have any suggestions on how to tune it to the right position? I have watched the video you suggested below using your bellows, but if you have any further comments on getting the 160mm exact I would enjoy hearing about it. I am taking your suggestion of starting with the finite objective and look forward to collecting and experimenting. Thanks
Thias series will be great. Hope you're doing well Allan. Greg
Thanks Greg! I agree. This is where the real magic happens in macro!
Thank you Allan! You have opened up my eyes at the right time! As I was just starting to research macro equipment options. I can't seem to find your next video for using this objective. Is there one posted? it would be really nice to get a visual (so many questions :) Also I'm trying to translate your Nikon setup & equipment list to my Canon EF/EF-S camera. Should we also be subjecting the Adapter distance? (the Amazon description objective-M42 says 52mm but picture 53.75) My camera example: Objective 160mm - 44mm(Canon flange distance) - 52mm Adapter(objective to tube) and tube to camera = totalling approx. 64mm'ish tubes? Thanks :)
Allan, great video, as always. I accidentally unscrewed and removed the cover of the Plan 4 objective you discussed in this video, that is, the outer barrel that has its description ("PLAN 4/0.1" and so on), which has no optical elements. I was left with a much shorter barrel that is much easier to "blacken" (to avoid any light bouncing back from the objective to the subject, a subject you explore in another video). Besides, you gain ca. 20 mm of distance between the front element of the objective and the subject. The removal of the outer barrel should not affect the optical performance of the objective since, as I said, the former does not have any optical elements.
Hi Gustavo, You are absolutely correct, removing the outer barrel makes lighting the subject a lot easier. The first copy of this objective that I owned didn't have a removable outer barrel (or it had been welded on!), but I replaced it with one that did - and I never use the barrel (except when I have it on a microscope).
My PB-6 unit arrived today, in fine shape from eBay! The rest of the stuff will take a while longer I'm afraid. Looking forward to giving this a go!
You are going to love using that bellows!
@@AllanWallsPhotography I plan to try it out by installing some of the bits and pieces I got along with the El Nikkor (from your previous videos). I intend to mount the bellows onto the worm drive Manfrotto rail that should be here any day now. Lots of experimenting to do! Thanks for the inspiration!
@@SomeGuyInSandy Yep... that setup will work really well!
When buying the RMS-M42 adapter, pay attention to the inside diameter. It is available with 25mm (= 1 inch) and 20mm (= 0.8 ").
The 20mm version is required here.
I've been waiting for mine to arrive from China for about 6 weeks, and I just checked and I ordered the 1 inch! Looks like I'll be learning this in the Fall LOL.
@@dawson207 same
I made the mistake of buying the 25mm version. Thankfully I only had to wait one more day to get the 20mm one
Just watched this video and really got my interest. Have had a look around your videos but cant seem to find the next one. Can you tell me the titles or addresses of the subsequent videos in the series for finite objectives please? Really pleased to have found your site as your style is easy to follow and REALLY well explained.
Hi Mike - sorry for the late reply. If you go to www.allanwallsphotography.com/blog and use the search tool, you should have no trouble finding all the videos and articles on the topics you are looking for. I am trying to find time to create an orderly back catalogue and will make an announcement when it is ready - that will help you follow along.
Is there a part 2 to this video? If there is which one is it ?
What would make a great video is you showing us your setup for 1x then 2x then 3x then 4x then 5x then 10x show us what equipment you use how Yousef it up and how you change your lighting,
I have seen most across different videos, but to have it all in one video
would be great
Excellent introduction, thanks!
What is the adapter needed to connect the Mitutoyo M Plan APo 5X to M42? It looks like the M Plan APo 5X has a 26mm male thread on the end. Can this be found in Amazon? Thanks.
hi Allan , did you ever do a follow up video to this showing the set up ?
Hi Clarrie, there are a few followups, including the Going Deep series, which you can find here: czcams.com/video/UT-vH9_p8XI/video.html
Great video! Now that i got the gear from your links here, which video to watch next, to start using this gear? Also, what mount do you recomend to to mount it all on, for stability, Below? I got a Canon 1 Dx btw. Cheers
Thanks for the question! If you go to www.allanwallsphotography.com and check out the "The Videos" page, you will find all my videos and written articles. The page is searchable so if you look for terms like "beginner", "bellows", "objectives", etc. you will find a ton of material that covers all the important basic content you are looking for. If you need something specific, and can't find it, just shoot me an email (contact@allanwallsphotography.com) and I will help you find it.
Just asking. Regarding to the use of M42 extention tubes and a short helicoid (M42 size) as you mention to bring the flange distance to 113.50mm. Instead of using a stack of rings I was planning on purchasing bellows. Could this be a good alternative way to get the same result??? Doing the math.....160mm - 46.5 = 113.5mm. Converting to inches...4 1/2". I believe this is within the boundaries of the bellows. Wouldn't this work the same and if so do you see any problems?
Allan thanks for sharing your knowledge so freely in your vids. I have a Canon 70-200 mm lens that I would like to try with the objectives. The screw size for the lens is 77mm so I am assuming I would need to purchase the RMS to M42 then the adapters that would take me to the 77mm, correct?
That's correct, you need a M42 female to an M77 male adapter ring.
Great post, thanks! I wonder if using APSC , will still be needed a 200mm lens, or should it be an equivalent lime 135mm?
Greetings Alejandro. When we get into using infinity objectives, the length of the tube lens will be how we control the magnification (i.e. the size of the image on our sensor) and all the calculations will be based on the size of the APS-C sensor. For example, using a 10x objective on 200mm tube lens will give us the full 10:1 magnification ratio. But if we change the tube lens to 100mm, we get a 5:1 magnification ratio. Your 135mm tube lens will give you a sharp 6 3/4:1 image. I will be doing an entire video on using infinity objectives, so this will be covered in more detail there.
I have a question please. I want to try and find one of that one you really liked,
but I'm curious, is it a particular brand or just pretty much any one with that # as long as it physically looks like that one ?
The reason I ask is I have a setup already and I don't know if my lenses are inferior quality or not, and they don't say "Plan" on any of them.
They do look pretty crisp but are missing that snappiness, possibly I'm just doing something not quite right, I'll need to watch your other videos.
I saw a short one you did on ultrasonic cleaning, I would have never thought of using mine for that, I will have to try it.
Below is just if anyone's are curious.
It's a used school microscope I bought. I cut the head off and Frankensteined things to fit my lens adapter, so this has a rotating head with the other mag. lenses in.
Thank you
Oh Dear Allan. You are tempting me to enter a realm I never thought I would even contemplate. Not sure yet that I am hooked. Old dogs and new tricks etc?
Haha! You should give it a try! It'll hook you in no time. The gear I will be using in the next video is mostly very affordable, but gives awesome results. I'm off the hardware shop again - had another idea for a project!
Effective aperture = marked aperture x 1+magnification, so f15 at 4x mage becomes f75. Simples 😀
Hi Alan, do I need the helicoid & extension tubes when I am using a bellows?
No. You will have all the control you need with the bellows. When using fixed-length tubes, the helicoid gives you the ability to fine tune the total length of your tube. They are good to have around and will be mandatory if you plan to use infinity objectives on a homemade tube lens. But for now, no.
In my scientific photography days, we understood macro photography was from 1x to 30x, then on to photomicrography-using a microscope up to 1000 x oil immersion, then on to electron microscopy. What we have today are really superb plan apo objectives by Zeiss, Leitz, and Olympus. Etc. There are now many sources selling microscope objectives at affordable prices and magnification range. Lots of fun once one heads into this area of photography.🔬🇦🇺🔭
Hi Shevill. I agree. A lot has changed and the newer tech has resulted in beautifully crafted infinity corrected objectives that minimize CA and make fantastic results more accessible than ever. The hard part is finding the perfect balance between quality and cost.
@@AllanWallsPhotography Hi Allan, Yes, cost is an issue, however I was looking online to see what prices are like for microscope objectives and was pleasantly surprised at what is available and affordable, for example; www.aliexpress.com/item/32991491109.html?src=google&src=google&albch=shopping&acnt=494-037-6276&isdl=y&slnk=&plac=&mtctp=&albbt=Google_7_shopping&aff_platform=google&aff_short_key=UneMJZVf&&albagn=888888&albcp=9437580887&albag=98363632680&trgt=296904914040&crea=en32991491109&netw=u&device=c&gclid=Cj0KCQjw0pfzBRCOARIsANi0g0tKm9D5_dJjgbJ5zV6zgP6EIcv-kZn8yRKuK9HmPmT9v0MHOxkie2oaAq3ZEALw_wcB&gclsrc=aw.ds I have bought many optical devices from these people and many other sources in China. Always testing new cameras, lenses and electro-optical devices for astronomy, my all sky cameras that I build and use, mostly for climate research work in universities, as well as my R/C systems for measuring inversion layers through the local atmosphere around industrial sites. So much has become available since I started some of my projects nearly 20 years ago, I would love another lifetime to indulge in many new goodies. I have some Zeiss plan apo low power microscope objectives and some Olympus 1x & 2x plan apo objective that I might experiment with some automated image stacking hardware/software now that prices are realistic for such gear.

Happy macro work from 'Down Under' Where do you hail from? I would guess the UK, but then maybe the US?
Alan,
Great information on macro photography, I am looking at the purchase of the extension tube as described in your video description.
My camera that I will use has a 20mm flange distance so from your explanation I will require to purchase a number of extension tube sets in order to reach the required 140mm after I have deducted the 20mm.
Am I correct or have I missed out on something.
Alan, I have on order the following I think I have covered all the items you mentioned as I was not sure of the extension tube length as in the previous message I ordered bellows. anything I may have missed?
1. M42 Mount Lens to Canon EOS Camera
2. M42 To M42 Lens Adjustable Focusing Helicoid Macro Tube Adapter-17mm to 31mm
3. 18Pcs Lens Filter Ring Adapter Step Up Down 37-82mm Set
4. Macro photography reverse adapter For Canon EOS
5. Microscope Objective for DSLR Camera Aluminum M42 to RMS
6. Macro EXTENSION TUBE 3 Adapter for M42 42mm Screw
7. 42mm Lens to EOS DSLR Adapter (Canon EF, EF-S Mount)
8. Universal RMS Standard Thread 4X PLAN Objective Lens 160 / 0.17
9. EMF AF confirmed for Canon Mount Macro EXTENSION Bellows
Hi Alan I would really like to learn about lighting for extreme macro, will you be covering this in a future video? Cheers Mark
Absolutely. This was just an intro. We will be getting into the weeds with lighting, stacking, etc. very soon.
Allan Walls Photography cheers Alan can’t wait for that one. I imagine lighting to be very tricky at such short working distances.
@@AllanWallsPhotography nice!! waiting new vídeos... good vibrations from Brazil!
How do you feel about the same companies 10x plan achromatic objective lens
It is not good at all - at least as a photographic lens. It has a very short WD, a narrow aperture, awful CAs, etc. There are very few really reliably good objectives that can hold their own as camera lenses. A few Nikons, Zeiss, Olympus , and Mitutoyos, oh and some Lomos. The Amscope 4X is a freak. It shouldn't be anything like this good, but it is. Unfortunately, that's it for Amscope - some of their objectives are nice as microscope objectives - but not as macro lenses. I am only a year late with this (I seldom get back to the comments but was here for something else and saw this), so you have probably bought the 10x, used it once, thrown it through your front window, repaired the window, had two grandchildren and one appendectomy, and have completely forgot about asking me this question. Weird eh?
I am sparked ! Would the equipment needed change with a Canon dslr crop sensor camera ?
not at all 👍
Well explained as always,but i admit that it was difficult to understand some things. Perhaps i will understand in the next video Good burgen from the thrift shop .Thanks Allan.
Hi Mario! I will be going back over much of this material again, in the upcoming videos. It'll all start to make sense!
@@AllanWallsPhotography Thanks Allan for your support you are giving me.
What would u guys recommend for Sony a6000
I would recommend the same setup described in the video. Your camera has a shorter flange focus distance and you would need to take that into account when adding the needed extension. Obviously, your adapters would need to designed for the Sony mount.
My kitchen's yellow, too, after an apple crumble and custard incident that I'd rather not talk about.
Hi. I am very new to this deep macro with objective lens. I have a ZEISS objective 100x/0.75 DIC. Can advise if is it suitable with 200mm lens ? Thanks. Love your video.
Hi Daren, I am afraid that would not be a very good lens for photography. 100X is too powerful and there will be very little light. I would recommend you look for a quality lens in the range of 4X or 5X - that is a lot of magnification for a camera!
@@AllanWallsPhotographyThanks. I love to watch your videos. Very informative.
Hi Allan - Where did you get your bellows? Great video! Thanks, Scott
Hi Scott. I use the PB6 bellows from Nikon. I found mine on eBay, a few years ago. They show up, sometimes in pristine condition, quite often. I think I paid around $200 for mine (don't hold me to that!), which isn't bad for what I think is the best bellows out there. The construction is of extremely high quality. I wrote a blog piece about the PB6. You can find it here... www.allanwallsphotography.com/blog/2018/9/10/nikon-pb-6-bellows-the-best-bargain-in-macro-photography-equipment-ever
Hi Allan: I collect minerals and have gotten into doing some macro/micro photography periodically. Have a couple cameras and lenses. Nothing too serious. But, I usually do focus stacking. I like your videos. When you moved the rear standard on the bellows, that caught my eye. Usually, I change the distance between the objective and the mineral. But, there are benefits to moving the camera instead. Have read about this online but never tried it. Thanks again for the reply. I will continue to watch your channel.
is it different for sony a7r2,3,nex7..whats the difference between ththe m42 and m42 type 2
Well, the mirrorless systems have a much shorter flange focus distance so you will need longer extension - but so long as the tube length gives the same separation between sensor and lens, you will be fine. It is something to do with the els attachment, but I am not a Pentax guy so I can't be sure - but you don't need either of these adaptors - all you need is a way to attach empty tube to your camera - so just get extension tubes made of Sony and you are good. The diameter doesn't;t matter. You just need to be sure you have an adapter for the objective that fits your extension tubes.
i would love to try all this!! can you recommend a microscope tho? i have nikon stuff and have all the parts in my amazon cart
Certainly! You want to find a microscope to prepare specimens? or you want the objectives to take pictures, or both? What would you use the microscope for (that sounds dumb, but the more specific you are with that answer, the better the advice I can give you). Email me at contact@allanwallsphotography.com and I will send you some links that might help.
OMG Allan - thank you, thank you, thank you. I have been wanting to get into this for so long and have bought a few bits and pieces but can't find anywhere that talks about the very basics and getting started. I joined a facebook group but when I was reading some of the information given I thought I'd have to have a physics degree. I really was being to wonder what I had done purchasing this stuff. These videos will be a god send. I live in a small town and obtaining the right 'stuff' is problematic if you don't have a clue what you're going to need. Again - thank you!
That's awesome, Natalie... I was uncertain about whether or not to get into this area. I didn't want to chase people off! But the response has been most gratifying and I'm looking forward to the challenge. I guarantee you will use every gadget and gizmo you have invested in. Thanks for the feedback!
Not to be a public nuisance but I use Canon products. I am very interested in this topic so I hope you could supply information for this type of EF product? Also, Laowa makes a 25mm f/2.8 2.5-5.0x macro lens that actually produces a very good 5x photo. Canon also makes the mp-e 65mm f2.8 1-5x macro lens. How does this initial setup you are offering in this post equate to these lenses?
I love this video and picked up all the parts necessary to try this out, but I'm stuck. Where, exactly, do you measure the 160mm? Is it 160mm from the subject end of the lens to the sensor mark on the camera? Is it from the back end of the lens?
Hi - the distance should actually be 150mm (the 160mm is the mechanical tube length and we need to use the optical tube length which is 10mm shorter), and you measure it from the sensor plane marker on your camera (ø) to the rear element of the objective. The good news is that it doesn't have to be perfect, just close, to get great shots.
@@AllanWallsPhotography Thanks! That helps a lot. I was getting pretty bad refraction issues, at least I assume that's what I'm seeing - I'm totally new to this - , so hopefully that issue will improve now.
Why he is not showing how to mount all system?
Dead Allen, i really enjoy your videos 🙏🏼 i learned a lot already. i can use it in my professional field. When i am good enough and practiced more i will support your patreon 🚀💪🏼 can you be so kind and update the m42 link and the microscopic lens link? They are not available anymore on Amazon and i would like to NOT buy the wrong ones. Ebay would be brillant 🙏🏼 thanks so much for your time Allen. All the best Jimmy from the UK / Kent
Hi Jimmy I did update the links as requested. I cannot see what the UK Amazon store has but follow the new Amazon link to see the lens you need. There is anther company in the UK that sells this identical lens under a different brand - I don't know the name. If you go onto my Discord server one of guys from the UK will point you in the right direction. Good luck!
The objective mentioned is out of stock on Amazon. But I found it on amscope.com. They also had the same item but in 10x. I know you recommended a different Nikon 10x, but that's $297. I might try the $50 AmScope version and see how it treats me... unless someone has tried it and knows it's bad.
Hi John, I did have that objective for a while but was pretty disappointed with it - the working distance is very short indeed, making lighting a challenge, and I am guessing that some of the geometric and chromatic aberration correction is meant to be handled by the AmScope microscope tube lenses that the objective is used with. I was never able to get sharp or CA/SA-free images with that objective. The finite 4X is a different story altogether - a wonderful lens.
@@AllanWallsPhotography Yeah, I tried it on a lark. It's inexpensive. The working distance, as you point out, is only 5mm.
I'll save up for the 10X Nikon you've recommended. But I LOVE the 4X you recommended too.
Hello! Great Video! I'm using my Sony a6400 with cheep c mount 180x zoom lens designed to work with hdmi microscopes. It works fine with c-mount to e-mount adapter but the only thing that i woudl like to improve is a working distance... With that lens it is about 9cm. If i will move camera a bit further then it is all out of focus. I know that hdmi microscopes have optics inbetween lens and sensor so they can focus the lens from different distances. Is there any adapter that can do that? Even if it is manual it woudl be nice to be able to focus it from further distance. Thanks for the video and have a great day! :)
I would need to know more about the lens you are using, but I suspect not. Most microscopes use an objective lens that is specifically designed to produce the nominal magnification ratio at a fixed working distance and a fixed tube length (or focal length for for an infinity corrected system). If you send me some more information about the lens and how you have it set up, I can give you a better answer (contact@allanwallsphotography.com)
Don't know if it's down to covid, but the shipping on the lens is over $80 AUD!
Would you also recommend the AmScope 10x objective?
I have the 10 and 20 Amscope infinity, inexpensive and are pretty good.
@@dro7684 What do you use to focus the infinite? I think David was talking about finite objective
dear allan, hope you’re well! I’ve been using the bellows+4xobjective that has the focus point at 160mm distance. I’m having a big difficulty on finding this exact point. I mean, I focus it manually by extending or contracting the bellows, but how can I know I’m exactly at 160mm with the sharpest focus I can get, and not at 161mm or 159mm with a fairly good focus but not the best possible. I’m sorry if there’s already a video about that, but I couldn’t find it. all the best!
Hi Lucas... first, if you are using the AmScope 4x objective, the distance between sensor and rear element of objective should be 150mm (the 160mm marked on the barrel is the mechanical tube length, which is 10mm more than the optical tube length - because of the eyepiece that a microscope uses). The easiest way to set it up is to take your camera's flange focal distance (46.5mm for Nikon F-mount bodies) and subtract that from the 150mm. The remaining distance is the extension of your bellows PLUS the length added by any adapters. For me, that means my bellows extension plus adapters should be 103.5mm. Set that amount of extension and double check it by using a straight ruler from directly over the bellows. Once the extension is set, do not change it. Focus on the closest point of your subject by moving the camera/bellows as a unit - but without changing the extension length. That will put you at the correct minimal focus distance (working distance) from the specimen, and will give you the full 4x magnification. When you start your focus stack, move from that position, forward through the subject, by moving the camera and bellows as a fixed unit, until you get to the furthest focal plane of interest. Having said all that, you can be off by several mm and still get very high quality images - so 148 to 152mm would be fine. Hope that helps!
@@AllanWallsPhotography amazing how careful and attentive you are on replying and making your videos, Allan! I've been learning a lot with you and my M.Sc. research on Engineering have been changing a lot since then. Now I'm studying plant and insect features that can serve as inspiration for new technologies. You may imagine the necessity of high magnification for that! Thank you very much. Learning with nature all the time. All the very best!
Alan, I use the Chinese market for items not available in the US...........in the last 60 days a number of items I've purchased did not arrive because of the rapidly developing concerns of COVID 19.........so be aware.............
Hi Terry, good to hear from you. Yes, I have several orders that are 4-6 weeks overdue. I almost mentioned it in the video - I will in the next one. I buy a ton of parts from China.
i use a website called (pinterest) you can see all kinds of set ups like this, the website is just the Best but one thing i dont see is a (Lens cover) to protect the objective lens.
find a short snub nose aluminum flashlight shape like a probe and since you can unscrew it you have two parts. epoxy the wide part of the flashlight over the objective now you can screw the back of the flashlight over the objective to protect the lens, in other words just like putting the flashlight on (backwards) over the objective.
if you find a large flashlight you can make a shell over the hole set up and make it look like a 1 piece probe set up.
if you think about it a flashlight shape looks all most like a camera lens and the shell of the flashlight would look better then looking at a bunch of extension tubes.
it would make it a little bit more cosmetic professional then looking like you went to the scrap yard putting a bunch of junk yard parts together :)
and for best design goes to >>Allan Walls Photography
I don't see your follow up video showing how you set up and use this method....
Hi Gordon, There are several videos in which this setup is used - this is a good place to start... czcams.com/video/JqFRwI__IA4/video.html
Well, this was very interesting, but also very slow, and not much information to go on yet. And you say you'll do other stuff as well? So maybe I should come back next year to see if you’ve completed the series.
I want to buy Tamron SP 90mm f/2.8 Di Macro 1:1 VC USD for Nikon F for my D7500 , so help me to buy the Microscope Objectives ? type and model 🙏😊
Hi Ata. Great lens! Start with a Plan 4x finite objective from AmScope - cheap, sharp, and a great place to start. Next you will want a Nikon infinity corrected CFI Plan 10x - one of the best there is.
@@AllanWallsPhotography 🙏🙏🌹🌹
Allan, thank you for the great tutorials. I have the Nikon PB6 bellows that I use with an adapter on Fujifilm X-T3 with an El Nikkor 50mm enlarger lens. It gives me the magnification I need for what I like to shoot (not bugs). But adding a microscope objective looks lke fun. Since I have the bellows, adding the objective is cheap fun!
NOTE: This website has tons of useful info for extreme macro: extreme-macro.co.uk
Hi Lysander! Thanks. Yes, the having the PB-6 makes a lot of this easier, if a little bulkier. There are some setups where the bellows can impinge on my lighting, but the ease of controlling tube length is worth it. I couldn't agree more about your recommendation! It is a great site and the first one in my list of recommendations in the program notes!
6:40 .... I hear your first words speaking about extremely sharp images .... etc. and I see this example image - which is DEFINITIVLY NOT TINY SHARP .... !!!!
Way To long.....go to the point......should show the setup and some sample image
Slightly soiled bed sheet....
Just started watching this...YUCK!!! sorry, but that yellow is UGLY!!!! ...going to try to trust you and keep watching..though this is hurting my eyes! 🤢
Far too long-winded. Even at 1.5x viewing speed. I gave up after 13 minutes!!
Yes - I agree. This is one of my earlier attempts and I am considering taking many of these videos down, but there are plenty of viewers who are not as bothered by the pace as you and I are. I think you will find the vast majority of my more recent material a lot less tedious. They still contain a lot of useful material, so I urge you to check out some of the more recent content. Thanks for the valuable feedback!
With all respect, your videos to me are extremely wordy. Try explaining it with less words and show what you’re talking about with various examples. I don’t want to hear about the history of this the history of that you’re washing machine, etc.
I am sorry, I have looked into a number of your videos as you cover topics I find of interest, BUT, I get incredibly frustrated by the amount of time it takes you to get to the point. I can't remember a single one of your videos I have tried to watch where I haven't dragged through the timeline to try to find you actually doing something, showing an image, whatever. You clearly have some excellent information to impart but you could do it in a fraction of the time you seem to want to take. Sorry, but unsubscribing, as my blood-pressure won't take the frustration of waiting for you to actually give me the information I am after or actually demonstrating what you are talking about!!
Hey Brian. I actually felt the same way you do when I watched my first Allan Walls video. With the second one I concentrated on how I was feeling when he included some commentary that had little or nothing to do with the topic at hand. Then I started thinking about some of the other videos I've seen where the tutor moves and speaks so fast that i have to rewind several times to absorb what is attempted to be conveyed. My frustration over that far exceeds my minimal impatience that tries to grab hold of me while watching Allan's videos. I much prefer the slow paced and relaxed disposition Allan has when taking the time to share his knowledge and skills with us. Besides, I find it a welcome diversion which has a similar effect as a rest. There are many videos on CZcams that are created by people who seem to be running a race with time trying to impress others about how fast they do something. I'm not aware of how many if any, people are actually impressed by that. Maybe some. I sit back with a nice cup of herbal tea sweetened with a little honey knowing that I absorb much more when the atmosphere is relaxed than I do in a 'let's race to the finish' one. Coffee, beer or wine may be someone elses choice but I prefer the tea and honey.
Can I use an Nikkor 200 mm AI lens as a lens to use with this objective?
WOOOWWW SO AMAZING, I JUST GOT AN OLD Olympus 10Mpix camera and I want to get into MACRO Photograsphy.....I just received my Microscope lens from Amazon and I was searching on the internet what elle adapters and extensions I need to attach the lens to my Olympus then I got your AMAZING video.. THANK YOU Sir. BRILLIANT
