Is the VR in this lens repairable? I bought one second hand and I never notice a difference when switching VR on or off. Sometimes theres a knock on one lens element like it was trying to move and then it stops.

Thank you! I just went to learn how to switch to manual aperture. I new to this photography stuff and they really did things differently back then lol

your istructions are superb. I have found that apart from this reason for jamming the back is that if the other side of the metal plate that helps lock and unlock the back is not perfectly straight it will also jam the back. But I would not have gotten there without your help.

Thanks! Brought my Nikkor 85mm 1.8 (K) back to life, it had a focus ring that was almost stuck - not anymore! 🙂

Do ever take requests. I have a Meyer optik oreston 1.8 (bought very cheap to repair). I can’t get the helicoid aligned correctly and I’m struggling so hard. I desperately want to learn how to fix it but I’m afraid I don’t know what else to do. I’ll ship it too you. I’m desperate

Thanks for this video! I was able to use it to do fix the sticking focus mechanism on my M10-P. There are a couple slight differences: the screws holding the top on are both T6. The second one is not under the little contact held in place with two Philips screws - but actually at the top of the battery compartment. In some ways easier! The hardest part was getting the thin rubber gasket back in place properly during reassembly! There are several small rubber posts (part of the gasket) that had come out during disassembly - carefully mushing them back in to place made it possible to get the top back in place.

I have a viewfinder like that, much cleaner, but the main glass of the prism, the one you cleaned, it's damaged. I watched the whole video hoping to see you removing that glass too, but from what I saw, the prism can't be opened and that glass can't be replaced. Kind regards from Roma, Italy.

I may have missed it, but did he mention that this lens is really quite radioactive?...and potentially dangerous to disassemble and work on.

Even with speeded up video - this thing is 5 times longer than it needs to be.

Hi, congratulations for your extensive work. I'm trying to clean the Summicron-R 35mm f2 version 1, but I don't know how to access the from elements. Can you help?

your videos have been a huge help on multiple occasions - including tonight! thank you!

Hi mikeno, I love your channel! I own an old Canon FDn 50mm f1.4 lens in a good condition. There is quite a bit dust in it though. As I do not own the tools for repairing it on my own, I wanted to ask you if you offer a repair service?

my 77-m4 has the same problem on the focus...did you make a tutorial for this lens?

i love u

Hello. I did everything exactly the same as in tutorial (about 50 times), and everything is fine till final locking: there is no way to set two red dots in the same position - the mount rotates and blocking about 7 millimeters earlier. Any ideas what to do with this problem?

Is a regular Chinese quality lens my friend, is somewhat the L Canon's ones but 50 years ago, that's why its heavy weigh. BR

Your channel is the best and has helped me a lot. I was always scared about putting my hands on a camera that expensive, but with your help i can fix my rangefinder wich should be adjusted in the "portrait distance". I always worked with the numbers on the lenses, not so good in portrais-mode! Greetings from Vienna to Denmark

If you have a D70 or D 100 there is another pin at the 8 O clock position to indicate min aperture is set Thus another cut out would be needed like the AI lens. .

Amazing work. Thank you for sharing

thanks!!

Is this applicable to the 50mm NFD 1.4?

The lighting effects in these episodes are not ideal!

Very informative. I hope I don’t have to do this in the near future;)

Handing a Zeiss or Leitz lens to an amateur for cleaning is like handing a Stradivarius to a monkey.

Another amazing video !! But I hope you can adjust/increase the volume of your commentary and re-upload.

Very valuable and comedic at times 😂

Thanks a lot!!! I restored the same lens 🇦🇷👍👏🤙

A camera that I never owned, but always wanted, the Fuji rangefinder cameras were my favorites, especially the GS645, compact, great lenses, quick to use! Thanks again for another great video!

If you clean lense by hydrogen peroxide so it doesn't harm the coatings of the lense???

Thanks, see you later

maybe the tiny spring cut short better

not good idea😢

Great video ! But the sound volume is a bit low for your voice. I have the volume all the way up and then the "ads" come in and blast my ears !! Please fix if you can, thanks !

What are the last three lock screws MPNs ? I would like to buy some as the current ones have damaged with their threads

Thanks, your video really helped me to repair and bring back to life this lens from a friend of mine. Is amazing this kind of content and also was a huge inspiration for trying to do this kind of content in my language, because I know sometimes the language barrier stopped a lot of people. Thanks, keep with this amazing content

Thank you. Seriously saved my life/lenses!

Hello Mike, would you by any chance have a video for the Olympus PEN-FV because my film advance lever is stuck. It won't advance. It also appears that the rewind button is depressed and won't pop back out. Please let me know. Thank you.

Thank you for your video!

After going crazy for a couple of days after other videos, I tried to watch yours, even if it was FM and not FE as in my case. Having identified the point you indicated, not being able to unscrew the screw, I made a small variation: a controlled spray of WD40 and magically everything started working again. I don't think it's the most orthodox method but it worked beautifully. I hope I haven't done irreparable damage with my change but I wanted to thank you for your precious and indispensable information! (translation by Google I hope it's understandable)

.... on another shutter topic ....(Sorry but I couldn't find any email or other contact for you :-) Do you have any video that would be helpful in repairing a "stuck" (won't fire at all) Copal shutter on the 80mm f3.7 Mamiya-Sekor for Mamiya 220 ? Thanks !

Very nice tutorial!

I have always been intrigued with the Seiko/Seikosha shutters, another amazing video from someone who always shares your knowledge experience, and appreciation of the mechanisms that allow photographers like myself to continue to enjoy the journey of the apparatus and the image! Much respect always, Sir!

That's a clever idea, Kenneth.

Hi Mike, I managed to get my lenses clean. However, now my shutter is stuck. I think it may be related to the fact, that I tried to use a wire release to keep the release shutter pressed. The situation is now that the shutter appears to be pressed and does not come out. It is not possible to change the timer setting from bulb to something else or or use the rewind lever. Do you have any idea what could be wrong? thanks and many regards, axel

Do you mind letting me know what is the name of the tool you are using at 1.06 time? To open the pig nose screw

No me sirvió de nada tu video

Thanks for the video! I never even knew about JIS screwdrivers! I had a problem with aperture stuck wide open. A few humble tips: 1. the bayonet screws were hard to turn on my lens, my screwdrivers were small with thin handle so not enough leverage. I wrapped the screwdriver handle with cloth, gently turned with pliers, the screws gave easily. 2. I had size 00 and 0 and used 0 (the bigger one) 3. I took the bayonet off, and then just moved that thingy that closes the aperture and the aperture closed. I worked it a few times and it was fine. So was no need to disassemble further. I used Vessel TD 51.

Fungus also lives inside the lens holder barrels. Did you clean those with hydrogen peroxide? Otherwise a nice very detailed video of a difficult procedure. Well done!

“Although this is an old thread, I want to express my gratitude. I have the same lens, and following your video instructions, I managed to smoothly fix the stiff aperture ring. Putting it back on was a bit tricky, but with patience, I did a great job. Thank you for your help, my friend! You’ve assisted me before with a Nikon F camera, and I appreciate it. Cheers!” 😊
