Edited: 2024-1-31. TTArtisan no longer includes the rear ND filter with their 7.5mm fisheye lens
A multi lenses comparison review like this takes quite a bit more time for me to do, but do you like this kind of videos and want me to do more? And What is your favourite fisheye lens?
I love these videos! Before buying these types of lenses it is hard to find the differences in all of their similarities. Thank you for your thorough reviews of this nature! They’re really helpful. The TTArtisan fisheye is supposed to be delivered to me today :) looking forward to using it even more now after watching this
Thanks for the comment Wes! Yes when I am looking at buying new gear I always want some comparison review as well that's why I create review like this and hoping it can benefit other potential buyers. Enjoy your new fisheye!
Yes please, do make more. This is Christopher Frost level and very fun to watch :)
I am going through a review period on the build up to potentially buying a fish eye lens. The 7 Artisans had been my previous favourite, but having seen the TTArtisan that is swinging it for me. On lens spec alone I might still have picked the 7, but the fact that the TT has an ND filter is a MASSIVE bonus to me, as I like long exposure shots and have never figured a way to attach any kind of filter to a non standard lens front. I see there is a slightly narrower fov, but I still think the TTArtisan will most likely win out for me.
Great review, thank you for your time!
Thanks for the video, did you try with 17 mm of this brands of lenses or the lowa??
Who is calling me! Here I am! 😁
Hi TTArtisan, I hope you enjoy this comparison review
Hi, TTArtisan folks! Thank you very much for sending lenses to Mr Wong for evaluation. He puts so much time into preparing these reviews. I have several TYArtisan lenses, so I like your excellent products.
Finally! I found a comparison video between the ttartisan and the new mark II 7artisans Fisheye! And even this detailed. Thank you Richard for this vid!
hey KoRna steniker, glad you like this comparison video :)
Very detailed comparison, worth the wait. Thanks a lot for the video. Please do more comparison like this in the future, subscribed.
Thank you! I will try to do this more in the future. But sometimes it's really quite hard to arrange all the lenses I want for the comparison review.
Great review- I went for the 7Artisans- got some nice Milky Way pics and some very good close ups- thanks!
Awesome, thank you for watching Jon!
This was a very useful video. Thanks for sharing!
Glad it was helpful!
Great, integral, review thank you. I have the 7 Artisans which I'm very happy with and don't think I'll be swapping for the other two.
thanks for watching! Enjoy your 7Artisans! :)
Thanks Richard. I got the ttartisans from b&h as it was free shipping no tax, which was the least expensive way to get it. I like the FF feature and f2
hey Barry, enjoy your new lens! :)
Very interesting review. Nice to see a comparison between 3 lenses. Thank you !
Another lens interesting lens to compare would be Samyang 7.5mm fisheye.
Thanks for watching! Yeah a few people have requested the Samyang lens unfortunately i wasn't able to get one for this review
Thanks for this excellent review!
Glad it was helpful!
Very nice! i like TTArtisan most but i agree they are all great and unique!
Thank you!
Thanks for watching Kenneth!
great review(s) - thank you for the comparison
Thank you!
Thank you, great video well done.!!
thank you :) think i'm gonna go with the 7artesians :)
Congrats for this excellent, comprehensive and very rigorous review. I really use the 7artisans 7.5 mm F2.8 a lot on my canon eos M100 and it gave me beautiful results. Strangely enough my copy of the lens has a F22 (maybe this is another generation of the lens) and not F16 minimum aperture and this is really of importance to control the amount of light when you are facing the sun at sunset or at the golden hour and generating sunstars. Another problem I encountered with the 7artisan fisheye is a very strong and asymetrical vigneting effect appearing only when using the highest shutter speeds (1/4000). I don't know if this only due to this fisheye lens or if this is some weird interaction between the lens and the M100. It can be used very creatively but it is a nuisance in most cases. I have been using long exposure photography recently and have needed to add a 3 stop slim filter in addition to a ND1000 to explore the full range of exposure values for pictures of the ocean on rocks. My guess is that ND1000 won't be enough with the TTartisan at F11. Can you pile these filters up at the rear of the lens? i reallly enjoy that you verify the field of view and light transmittance of the lenses. You are the only one who is doing this and I feel that it is really useful. I would also suggest to look at color rendition...
Thank you for watching Steven! Yes the 7Artisans i used in this review is the version II. I've just updated my title to make it more clear which has f/16 minimum aperture. No you cannot pile the rear filters on the TTArtisan, only one at a time, and it only comes with a ND1000 as well for the retail version.
Thanks for the suggestion re colour rendition. i would try to include that in my future comparison reviews.
@Chomp Chomp Katze thanks I did not know there were two different Mark I versions
7Artisans Mk.II has the best corner sharpness and widest FOV. And when I saw one in the Lazada sale for only US$65 equivalent, I bought one. At that price, it's a bargain! Ps. I think it would have been instructive to tell us what impact the ND filter in the TTArtisans lens had on colour rendition, sharpness and IQ.
I purchased the TTArtisan 7.5, and used it a lot in a month, but decided there HAD to be Something Better than This!
The Actual Lens I got, was not Flawed in any way, it just did not seem Sharp Enough to me at all.
I was used to the Very Sharp Rokinon 12mm F2 lens that I had been using for a year or so.
So I bought the 7Artisans 7.5mm, and had no problem selling the TTArtisan on eBay for what I had paid for it.
I was going to buy the Rokinon 8mm f3.5, but for some reason the Sony E-mount version of this lens is Huge,
in comparison to the TTArtisan 7.5, so I went with the 7Artisans 7.5... I have the Same "Mark II" version as in this Video.
I am very Happy with the Results I get from the 7Artisans especially after I shot many of the Same Locations I had shot before,
using the TTArtisan lens. The 7Artisans did a Much Better Job.
I am reading so many Comments here, and to me it seems that so many people are Confused as to what This lens IS...
It is a "Fish Eye" Lens, that is Purposely Made to give you that Distorted Perspective... it is Not just a "Wide Angle Lens".
I do not know if Any of you have ever used a 35mm Film Camera or not, but if you did, you would know that the "Normal" Lens,
that gives you an image that is about the same as it looks when Not looking through the camera, is a 50mm Lens.
Anything Less than that 50mm Lens, is going Wider ... so 35mm is Slightly Wide Angle, 28mm is the Average "Wide Angle".
Wider than 28mm you are getting pretty wide, and the lenses start getting more expensive. A 20mm Lens was considered "Ultra-Wide".
So this is the Same if you are using a Full Frame Digital, with Lenses that are made for that Full Frame Sensor.
With an APS-C Sensor Digital, most people got an 18-55mm Kit Lens with that camera. Most APS-C Sensor Cameras have a 1.5x
Conversion Ratio, and Since the Lenses are given the Rating of a 35mm Film, of Full Frame Digital, that 18-55mm Lens, is actually
a 27mm to 82.5mm lens.
So the 18mm end of that zoom is "wide angle" and the 55mm end of that zoom, is getting into "Portrait" range...
To get an actual 18mm "Wide Angel" of view on an APS-C Camera, (which is Very Wide on any Film Camera or Full Frame Digital) ...
You need to buy a 12mm "Ultra Wide Angle" lens, like the Rokinon / Samyang 12.mm F2.0.
That 12mm Lens, is Really Very Wide Angle, to go to something like the 7.5mm is almost Twice as Wide... like Super Wide!
But realize it is MADE that way On Purpose... the Perspective Distortion it gives you is On Purpose, for You to be able to
use that "Tool" to have a Variety of Creative Applications, and for sure "Stand Out" Photos.
So Why someone would use "Software" to "De-Fish" the Fish Eye is Beyond Me... when the Whole Point of Using a "Fish Eye Lens",
is to Create that "Distorted Perspective"... Just use a 12mm Lens if you just want Very Wide Angle Photos, without Fish Eye Look.
:>)
Thanks for watching and sharing your very detailed thoughts and experience!
@@TheRealRichardWong - Love your Videos, and your Photos as well.
Thank you very much
thanks a ton for the update , i am just ordering the lens i just thought that TT artisans 2.0 will make a difference but thoroughly after ur comment and the video by the author i would like to buy 7 artisans i just it will not do a drastic change in low light i guess with TT artisans. The quality it seems 7 artisans are good . whats ur comment on this should i go for 7 artisans
A nice review, and very timely for me, personally. Budget lenses don't often get the rigorous testing they deserve, and I appreciate the effort. I currently use the 7Artisans 7.5 mm F\2.8 on a Canon M6 II for astrophotography. The results are quiet decent for aurorae or Milky Way shots, but I've just upgraded to the Canon R7, and I'm looking for something similar for the RF mount. I am not sure if these lenses are available for RF yet, so I guess I need to be patient..
Glad the review helped :)
I have the 7Artisans 7.5mm f2.8, it is pretty good as a wide angle lens. Not so good in really low light indoors, but still great in middling light for the aperture size
Buy some external flash.. TTL version is much better.
Fish eye + bounce to the roof flash is nicer for fisheye indoor
Tough choice. All great lenses and fantastic value.
Thank you for this review. For me it would be the 7Artisans as ease of purchasing swings it, it's available through Amazon UK.
That does make a difference :)
7artisan looks sharpest, closely followed by Pergear, plus I really Iike the defined 'ring-flare' on the Pergear, could be a cool effect. Love the addition of the filter on the TTartisan - but it is a bit soft.
Very helpfull, I go with the 7artist
I love your yellow motif.
Thank you very much Rattus
I have the 7artisana mark I. It has adjustment screws for infinity focus adjustment. Looks like mark 2 doesn't?.. I am so impressed with it use it regularly especially for church and cathedral interiors... Thanks again for a super review..🙏♥️🙏
My uncle owns 7Artisans and is very happy with it. However, I would choose TTartisans as F2 and ND filter.
Glad I own the Pergear. It does a good job. Just leave it at f5.6 - f8 and it's great. Plenty wide enough to crop and not worried about soft corners. Worst thing is the metal cap. Bit of a nuisance!
Very good video 👍🏼
thank you!
Before seeing your review, I would have gotten the TTArtisans but the sharpness of 7Artisans is most important to me. Lack of corner sharpness is the biggest problem with fisheye lenses.
Glad my video helped you to choose your favuoirite fisheye :)
7 artisans fov being 10 degrees wider is nice too.
Thank you for a very detailed and very informative test. Maybe I overlooked something, but I can't see with what camera these test scoots are made?
I've watched this review, sooooo many times :)
Thanks Campbell! Hey do you create some video on youtube as well? I thought i watch a video the other day the channel has same name as you!
@@TheRealRichardWong Yeah, that's me. This is my work email, so it looks different. Was the video one of my photo ones, or camping, motovlogging?? Have a few different interests :) Love your channel - you are a great presenter. Camera Conspiracies gave you a mention the other day, which was cool. It is so great having a NZer doing camera reviews.
@@TheRealRichardWong OOOOhhhh question - 7artisans does a 10mm 2.8. Do you think they'll ever release it in X-mount?
@@campbellrousselle9752 That is a full frame lens so it's quite unlikely it will be relased on a APSC only mount. All the 4 other mounts this lens was released for has full frame + APSC camera available.
Do you want a slightly more narrow fisheye? (if there is such a thing)
this is an amazing review. Thank you so much
Thanks for watching Aalochak
Very helpful, thx
Glad it helped
Hey Richard, what camera and lens are you filming this with? Also, how far away is the camera from you? I really like the look of this talking head video. Trying to replicate something similar. Thanks, Richard!
hi Zander, i was using my Lumix S5 with 20-60 kit lens, camera was about 1.5 meter from me.
Outstanding...🙏👍
Thank you! Cheers!
Nd filters for video use. Thats a very important factor for me.
Hello Richard, thank you for this very helpful video! But I still don't know which one is better for me, I like astrophotography so thinking about getting one of these to get wide angle photos of night sky. Would you recommend the TTartisan or 7artisans more? Thank you!
Hey Winnie, for night sky/astro photography, the TTartsian would probably be the best choice as it allows you to shoot at lower ISO
Thank you! 😊
I know it's a different pricing, but it'd have been nice to see the Samyang version, it's also 2.8, I use to use it a while back I should've kept it! It was small and built like a tank, not sure how it compares with these tho, it's an old lens!
I am wondering which lens to choose TTArtisan 7.5 f2 or 7Artisans 7.5 f/2.8 II, I will be shooting both in good and low light. Is there a big difference in sharpness between the two lenses? If the difference is negligible, should I choose f2.0 because of the light?
Thanks for your job. I've got tt artisan. I think, it give more chance to make art photos with f2 (boke, night scene) and nd1000 (rivers,sea or street photos)...
Awesome! Enjoy your fisheye :)
Nice review. I suppose TTartisan is the most expensive one but I would still take it if I were using ff, one extra stop can make a big difference in some situations. 7artisan iq seems a tiny bit better than Pergear, but Pergear really looks good. If the build quality is as good as its looks I would go for Pergear
Thank you for watching Sam!! :)
What about Risespray? Is the same lens as 7artisan, Pergeat
Thanks for the review!! Ive chosen 7 artisan! Btw what is the music you used in the video its sweet!
thanks for watching! re music, sorry I forgot the title but that's from Epidemic sound
Which of these lenses do you think would be best for handheld low light video on a Micro 4/3 camera? Is the weight difference small enough that it won’t matter for longer shoots, or is it pretty noticeable over time? I plan to defish in DaVinci Resolve, so I am also concerned that corner sharpness could be an issue if it is exaggerated by the lens correction. Hopefully the extra crop factor will help reduce this, but do you think it would make the 7Artisan lens better, even in low light?
The weight difference is quite small i don't think it would really matter in real life. For low light, the TTartisan would be the best because it has a 1 stop advtantage.
Re- defish for video, sorry i don't have too much comment.
Is ttartisan 11mm f/2.8 better than 7.2mm f/2 for full frame? Or it's the same lense.
Hi Andrew, sorry i have not tested the TTArtisan 11mm fisheye yet. But if both lenses are used on a Full frame lens, the 7.5 would give you circular image while the 11mm is a diagonal fisheye so the image would look quite different
Quick question: for the low light indoor shooting is it worth to get TTArtisan 7.5 f/2 (due to the F/2) over the 7Artisans 7.5 f/2.8 (sharpness)? Please help :)
If you are struggling with light not enough light I mean then yes definitely
It seems to me that the TTArtisan frame is narrower than the other two. It is closer to an 8.5mm focal length
Which fisheye lens doesn't give the "circular" view on full frame camera (canon r5)?
these are all APSC fisheye so for R5 i suggest you look for a full frame fisheye. But what do you mean by "circular" view exactly? do you mean the distorted view but the photo does fill up the frame?
Great video!! Can you use these fisheyes on a Full Frame camera (S5ii) in crop mode (apsc) so it won't show the circle (360 video look) but the normal fisheye look as per your shots? Cheers Mate :))
No not really. you'll still get the circle look in the center, but black area outside
Can You compare the 11mm f2.8 vs 10mm f.2.8 fisheye
Loved this - Think my picks are TT Artisans and 7 Artisans. I like the 7s smaller and lighter size. I like the TTs Filters and overall characteristics optically.
Thank you Campbell for watching and share your thoughts!
@@TheRealRichardWong Such a useful video. I like the tiny Laowa 7.5mm, but it is pretty expensive. These are good alternatives I think. I think the Laowa is less fisheyed.
@@campbellrousselle9752 Isn’t the Laowa 7.5mm a rectilinear lens?
@@rumperdumper Not sure - Richard Wong will know. I was just basing my thoughts on the optics shown in this review. I bought a Fuji XT4 in the end, so will probably look at the 12mm focal length, although, maybe I should check out some reviews of these wide 7.5 lenses, and how they work on APSC. :)
How does this (ttartisan 7.5mm f2.0) compare with the ttartisan 11mm f2.8?
Both are around the same focal length on a FF camera but going into apsc mode means I lose some megapixels with the 7.5m f2.0.
I use an A7IV btw.
If you shooting on a7iv I think you should get the 11mm. I haven't try that out myself but doesn't make sense to buy a apsc lens to use on full frame when you have a choice
Hi! I stopped by because I don't know what's better. I just want to know your opinion. For you, which lens is good for creative photoshoot like portraits and street photography? Is it TTArtisan or 7artisan? I am torn between these two lens.
I may choose TTArtisan because of it's faster f/2 aperture
Thanks for a helpful review. I bought the TTartisan and whilst overall I like it, I note that it no longer comes with an ND filter; I can't find one elsewhere to buy separately. My other bugbear is that the lens cap is not trustworthy.
oh really? not even one ND filter? that's disappointing as i think that's the major selling point of that lens.
Yes, I bought both the TT and 7, and the TT no longer comes with the ND Filter (also confirmed this with B&H). Comparing the two, my copy of the 7 is much sharper (and wider) than the TT, therefore I returned the TT and kept the 7.
Plus...The Lens cap on the TT really bothered me...doesn't stay on correctly
I take it that it's better on the 7?@@KayakMark34
The Lens cap is much better on the 7.
Also, I forget where I saw it, but there were only a couple of reviews I found of the TT using the included ND filter, and they were not very positive...noticeable loss in sharpness, and some "double imaging"...??...Maybe that's why they no longer include it?@@kitwolf2857
What about the Samyang/Rokinon 8mm f2.8? It was by far one of my favorite fisheye lenses.
sorry Geroge, i wasn't able to get hold of a sample for the Fuji mount this time
Nice review!
just few things to mention on TTartisan:
1) it's a 10mm fisheye according to PTgui software and you have a clear visual confirmation comparing to the other 2 lenses.
2) the ND filter creates double images or ghostings around contrasted areas.
On your photo is slightly visibile on the first pole on the right; if you do the same test under daylight, the ghosting will be more visible (around roofs, poles or even trees) and image is unuseable.
3) mechanically the lens aperture can close past of F11, i think F16 or even F22 but TTartisan decided to stop at F11...good choice since diffraction would kill the sharpness; sweet spot is F8
4) my lens has worse quality on the right side of the pictures and the aperture ring has the engraving slightly misaligned
Good info thanks for sharing!
QC seems to have let one slip through. To your fourth point, sounds like the lens is decentered.
I have 7artisan 2.8, ¿which nd filter can I use? help!! by the way, excellent video.
Thanks, unfortunately there is no easy ND solution for the 7artisans
risespary 7.5 mm is it worth to use with a7c
hello, I have a canon r6, to mount the 7 artisans on the machine, an adapter is needed or is there a version that I can attach directly. It's R assembly.
I don't think you can use an adaptor as the flange distance difference between these mounts are so small. Also these are apsc lenses so not best for your full frame r6
@@TheRealRichardWong there is tt artisans for canon r6 assembly
but from what I saw in your review, artisans is superior
Thanks for great review. What would be your recommendation, for use with MFT-Camera?
Thanks for watching. They all have their pros and cons so you need to pick one that suits your requirement the most.
Sharpness is the biggest issue for me because of the higher mtt crop factor. So I think the 7artisans might be the best for me, but I'm not sure.
*Sorry mft
@@gert2030 If you would shoot at maximum aperture a lot, the 7Artisans is the best choice! But if you would stop down a bit like shoot at f/5.6, then the difference isn't that big
If I'm understanding right, the big aperture is the biggest advantage at the ttartisan. If this not not really unusable with mft, why pay more money and carry more weight.
Which would you prefer from those 3 for indoor lowlight?
for indoor lowlight, TTArtisan would be my choice becuase it's 1 stop faster
I just got mine but does not display any images on my Olympus screen nor can i take any pictures. No issues on all other manual lens i have. Waiting for TTartisan’s reply.
Hey @AndRam try remove the lens and mount it again, and maybe twist the mount a bit as sometimes if the lens is not locked correctly, the Olympus camera would not recognise there is a lens and there will be black image. Don't need to use any force though as you don't want to break anything. Just a gentle twist of the mount should be enough.
Ok. Got it working. I had to wiggle the lens left and right after mounting to make it work. The inner lens mount is interfering with the electrical contacts on the camera.
Great you got it working now! Olympus is a bit more picky on this. With other camera brands, it doesn't matter but Olympus need a "dumb" lens to fit perfectly to work.
@@TheRealRichardWong Thanks for your reply anyway Richard. I figured it out trying to attach the lens with the camera turned ON. The display would go blank as soon as I twist the lens. Then i saw your reply too.

Are there any full frame ultra wide lenses with rear filters?
There are some full frame fisheye that takes rear filter, I had an old zenitar 16mm fisheye that does that.
@@TheRealRichardWong what about rectilinear wide lenses with rear filter? The only option is Laowa 10-18? Is that a good lens?
How do they compare to a FF lens like the samyang 12mm 2.8?
hey Carlos, sorry i haven't use the Samyang 12 mm so can't really comment
@@TheRealRichardWong that's ok
hello, I bought the TT artisans 7.5mm for the Canon R and the lens makes a black circle around it. I wanted one that didn't make that circle.
Is it normal to do? I think this is for the hood, but isn't there a version with a detachable hood for the Canon mount R?
Canon R is a fullframe.
If you want fullframe for canon R.
Go with 10mm or 12mm to be the safest..
7.5mm for fisheye is only for crop sensor..
You have to know your camera, you can search in youtube what is the difference between FX and DX sensor.
FX is fullframe
Is 7 artisan fits sony zv e10
yes it does
The quality of these lenses is very random, depending on the particular sample you get
Damn the font 7art used on their lens looks awful... Trying to design a vintage looking lens and using a modern font on it...
Yes agree. A bit more attention to details in small area like this could dramatically improve the feeling and perceptual quality of the product. This is something a lot of the Chinese optics brands still not doing very well.
Who gives a sh*t about the font? It's for taking photos/videos, not posing around!
@@QuicknStraight who? Me, and many others, not you. You are like the one that says "who gives a sh*t about decorations of the house or the food? As long as the house keep you safe from storms and the food is eatable. House is for sleeping, pooping, peeing, not posing around. Food is for eating, not posing around". Lol.

@@QuicknStraight ah yes, clothes is for covering private parts and keeping warm, not posing around, so I bet you don't buy the nice outfits.🤣
you can put normal filter on the tt artisan?!!😮
Kind of, it's a rear filter but if you can find one with the same size yes you can
@@TheRealRichardWongwhat is the size of the ND filter for TTartisan to buy it separately? Thanks
Oh I just checked with TTArtisan. They said the rear filter is a special order one so it's unlikely you can find an off the shelf filter that fits

Any comments on the Samyang 8mm mk2 and the Meike 7.5 mm ?
best one is the Rokinon 8mm f/2.8 UMC Fish-Eye II but you were too cheap or lazy to research it.
