Cleaning lens elements in Leica A Elmar 1:3.5 f=50mm with Hydrogenperoxid 3% and Lighter fluid

- In this video I'm cleaning the lens elements in my old Leica-A Elmar 1:3,5 f=50mm (I don't have a Leica A camera...).
To disassemble this lens, you begin with the little set screw on the side.
If the retaining ring is to tight, you can use "nail-polish remover" with Acetone to soften the threat lock and then unscrew the retaining ring or the front ring
I use "PEC-PAD*" lens wipes together with the Hydrogenperoxid 3% and then use lighter fluid to clean the rest. It turn out to be very good.
I know I could have done more on the front lens but it was actually just to show you that it really work's.
But it was also to show one how this lens is disassemble, when the lens element's need a cleaning.

Thank you for this comprehensive demonstration. It's going to be very helpful to future technicians and photographers who have to maintain their own equipment in the future.
Excellent professional job of cleaning the lens glass. But the greatest pleasure is to see Mike with such love and joy to perform each of his works. My sincere respect. Best regards and take care. From México City.
Thank you for the great video! Very good instruction! It just came in handy for disassembling, cleaning and reassembling my Industar-22 (1955) which only differs in some details! I use this with my Leica Standard E (1932) because I don't have the original Elmar 3.5 / 50 nickel.
This is the very reason that I am here. I'm about to clean my Industar. 👍🏻
nice in-depth video, thank you! And to everyone commenting on his cough... mind your own business 😤😂
Industar 5cm f3.5 is basically identical to this lens in every way. Wow.
Congrats on the 400th video! You've inspired me to buy broken cameras and fix them myself so I've been doing it for like a year now.
I'm happy to know that, I hope you have a lot fun wih repair different camera stuff.
what a beautiful lens!
thanks for sharing this with us!
i dont know if i would dare to clean my lens like that!
thanks, my favourite tip is using bits out of a printer, and it just so happens i had those parts just in case, now they are usefull.
Very interesting, thankyou for sharing!
excellent video, well shot and presented. I have a 3.5, 50 Elmar that needs exactly the same job and i wanted to find how to go about it. Those rubber tools might be wise to get before i start...
You are a treasure man
Kenneth:
I love your helpful videos. Maybe you can help me in cleaning my 3.5cm, F3.5 Leica LTM Summaron lens. I have been able to remove the outer lens elements (front and rear) held in with threaded rings but i cannot remove the inner lenses to access them or the aperture blades. I have tried unscrewing them using rubber cones and even tried dropping a little acetone around the lens to break the threads biut nothing comes loose. Is there something I am missing? I cannot find a good diagram of the internal pieces of the lens to understand its deign.
Amazing thanks for sharing👍
@mikeno62 do you have a repair guide for the 3.5cm f/3.5 Elmar ?
I have a original elmar from a 1a and the light trap bit at the back is seemingly one piece. I can see threading or ribbing of the metal just behind it. I have tried using all the force I dare to remove it and have had no luck. I think it might end up being a case of destructive removal and then machining a new part from brass.
I have a meter model, serial 83 XXX and it has light baffles behind the rear elements that are painted in with no notches, I pretty much stopped watching at that point :-)
Hi there; is it possible that the base plate with the meter scale could remain on the camera while unscrewing the lens? This occurred on my Leica III
Thank you!!
To remove the lens from the body is it simply a case of removing the screws on the lens flange and lifting off?
Hi for those interested I just dismounted a summaron 35mm f3.5 (gauss formula) and was able to clean it and suppress all the haze. The dismounting is a little different from the Elmer here. So if Andy body interested tell me I can help.
this is very interesting
Hi dear, can you help me to find the item down below of this lens ( the adjustable focusing the lens). Because i have a enlarging lens hexar 50mm f÷3.5 but I don't know how to buy the tube which adjustable focusing. Thank you.
Congratulations.
hello! is the focusing of this lens difficult, for video?
Not really but the distance to the sensor has to be correct in a way so you can get the correct focus.
Hello Mike 62, this nail polish remover, does not harm the lens?
My name is Eden, I'm from Manaus Amazonas
Thank you
Is it possible to repair a scratched front lens? Repolish or spare lens replacement?
I'm by no means an expert on that. But if the lens is not coated and the scratches aren't very deep, I would say that repolish is an option. If it's coated you'll remove or damage the coating by doing so. As I said I'm no expert but I don't think that repolishing will affect the optical properties of the lens, in my opinion is better than having a scratched lens anyways
Excellent video !!!!! What sizes are the screwdrivers you use ?
Thanks Rino, I use a 1,2mm flathead screw driver.
Hello Mikeno..thanks so much for this nice video..where did u find Those rubber tools????

And you will also need some Isopropylalcohol 99%
And sometimes Lighter Fluid that is very good to clean lens element's.
NOTE: Do NOT! use Acetone on platic part's, it will damage / melting the plastic!!!
I would like to know how much it would cost to cla my lens
Hello Sir, wonderful instructions, I am fairly confident I may be able to clean my similar Leitz Elmar 1:3.5 50mm, although mine does have a serial number so it may be a bit more recent than your sample, all of the elements of the lens you are working on are the same (so far) as my lens except the first two rings (light traps) you remove from the inside. Mine does not appear to be two pieces. I have photos but not sure how to post in comments here. I cannot determine if mine is a pressure fit or just how to remove it. Any ideas or source for diagram would be much appreciated. Wonderful channel, a bit addictive I must say...
I am having the same issue. I do not want to damage it
@@james5553 Hi I have same, and it just pulled out by my fingers
Where is the camera the lens came off of ?
Impressive video but still would leave it to the professionals. One question and suggestion. What would be the adapter to use with an M4 mount? And if your trying to agitate the lens in the solution, why risk it with the end of metal tweezers? Why not use the q-tip or something softer, maybe plastic?
please tell me you can wipe the lenses medical alcohol?
I will work fine if it's Isopropylalcohol 99% or 90% or 70%
Great video. I will definitely return to it. (Minor point but it is my pet hate! - plural words in English do not have apostrophe - so videos, not video’s; thanks, not thank’s etc.)
Thank you, and thanks for the words explain :-)
I have watched many of your lens cleaning uploads and find them fascinating, but previous ones seem to feature alcohol for lens cleaning. Do you now prefer Hydrogen peroxide with a lighter fuel finish?
Thank's, when I try to remove fungus or haze in the previus video's, I use lighter fluid because it was the only solution I know about and it work's in many cases, but someone mention that Hydrogenperoxid work's better somtimes mix with water or/and Isopropylalcohol.
So I have now try it in many lenses with serious fungus, and it simply do it much better, and in my opinion when do the rest of the cleaning procss with lighter fluid it just do the job and it surprise me everytime.
But it also tell's that, there is not only 1 solution for cleaning lens element's, it depence what kind of haze, fungus, dirt, dust or oil film that's in side the lens, I try to shift between the different solution's, just to find out what work's best.
My list of solution's so far:
Lighter fluid.
Isopropylalcohol 99%.
"Eclipse" sensor cleaning.
Hydrogenperoxid 3% mix with or without water.
Dish soap in a ultra sonic cleaner.
Dish soap
Cheers
Kenneth
Do you accept cleaning lens job? I have 3 Elmars that need cleaning.
Sorry, I do not have repair service.
Don't use too high of a Hydrogenperioxide concentration or you could ruin the lens element that are cemented.
I only use the Hydrogen Peroxide 3%.
@@mikeno62 Try mixing it 3 parts distilled water to 1 part peroxide.
Had to watch this with the volume off as a cough is very annoying. Need to have that seen too.
Yeah, I was sick at that time, sorry for the annoying noise it affect in the video...
Is your health better? I noticed you were clearing your throat a lot
Thanks Dale, yeah I'm much better (no Corona...)
Drink some freakin water, FFS! 🤦♂️
Why do you use the "idiot's apostrophe" in "400 video's". This is plural und you write it "videos". Only genitiv is written with apostrophe: My father's house"
Yawn.
