- There was SO MUCH Oil on the aperture blades In this Ai-s Nikkor 135mm 1:2.8, but it's not so hard to fix, just REMEMBER to set a mark on the out side of the lens assembly, so you will know that the aperture value is correct when assemble the aperture assembly again.

You are a crazy genius.... I don’t know how in the hell you can take one of these apart and put it back together!!! I can no longer complain about lenses being too expensive. What is even crazier is that this is an OLD lens! I have one too, this is how I found this video, I love my Nikon 135mm 2.8, glad it doesn’t have this issue, such a great lens.
Awesome video, you do great work, thanks!
As someone who loves to clean their own lenses, I thoroughly enjoy watching your videos. Keep up the amazing work!
Thanks Jay :-)
Nice job. I can feel the pain of reassembling that tricky aperture mech; then realising it was out of the mark and having to dive back down the rabbit hole.
Yeah Gustavo sometimes it can be a little difficult to put in the aperture system, adn in other lenses it's so "easy".
i got my ai 135mm 3.5 from japan (ebay)...coming this month...i bought it for 60 bucks..with minimal fungus (according to the seller's description)..with your disassembly tutorial, i think i can manage my vintage lens to clean it..thanks for your video..
hi Kenneth, good tutorial as usual. Just one humble remark from my side: I found it easier to have the spring fixed on the other pin. Cheers!
Luca
Thanks for mention that :-)
Hi Kenneth, I think I became fixated on that drop of thread lock for a while! Great video as always. Thanks!
Well Tom, it was a while I have used the Loctite 243 so it was a bit dry up in the nozzle :-)
Kenneth: amazing video, thank you! I have the pre-AI version of this lens and have ordered a #42 modification kit. My question is, do I have to remove the mount from the lens before I can remove the aperture ring? The aperture ring appears to have two screws in it. Thank you!
Hi Mike, congratulation. May you explain how to remove the frontal lens without scratching it? I am worried to use the classic lens spanner. Maybe a different tool would be better. What do you suggest? Thank you. Best!
Very good
Excellent
Hi Sir, I just want to say your videos are very helpful. BTW. I am currently working on the same lens and it has lots of fungus. Is it difficult to remove and clean the glass on this lens? Also, do you have any tips that I need to follow before I clean the glass? Thanks!
Hello Mike,
I’ve been your admirer for many years now; you are a master.
With your hands on videos I have been able to rescue several Nikon lenses.
I know this is not “accepted” method, but after striping to of the five screws on the 135mm mount ( had to drill them out with a .5 mm drill bit) and destroying the threads on one hole...
I decided to just put the whole diaphragm assembly in hot water and then on a ultrasound cleaning...
It works and looks clean.
I’ve done this with shutter lenses for large format camera lenses and it also works....
Is this an acceptable practice in your opinion?
For me it is, since the chances of screwing up detailed work increases exponentially in my case.
Best and keep up the good work
Thanks Fernando, this is an interesting way of doing the cleaning and if it work on long term then I would think it's okay. But on the other hand you can not be really sure that all the old oil or grease came out in the cleaning process, there can still be a thin oil film in the assembly. So after this kind of cleaning it could be interesting to fully disassemble the aperture assembly and have a closer look, just to see how good was that method. Keep up the investigation :-)
@@mikeno62 Really appreciate your reply and advice.
Will do the forensics with the next one I fix. I'm pretty confident it got read of most of the oil (hot water first submerged and rinsed, then the ultrasound in a solution of ammonia and alcohol) I could see the oil escaping the assembly; it got pretty dirty.
Also I used a bit tiny bit of Nye synthetic oil on the focusing threads (this oil is fantastic; it's designed to not oxidize for 50 years approx. this Nye oil type is put into space satellites...
This lens was a basket case i.e. two of the interior screws that hold the lens assembly were loose, I had to apply glue to those.
The fungus I got rid of with vinegar (nothing works like it, not even peroxide) it wipes right off.
It take great pictures
Are you in Europe? hope thing are getting better over there, here in the USA it seems to be improving
Stay healthy
Which size cross Philips head do you use to release the 5 screws at the back plate? I already used nail polish and a ton of screw drivers but non of the ones I have seems a perfect fit.
Philis screw drivers will not work as you think, it should be the JIS screw drivers (Japan Industry Standard) and together with "Nail polish remover" with Acetone on a cotton bud or Qtip, or you can just use Acetone on a cotton bud, it will most of the time soften the thread lock so it should be possible to unscrew.
Don't use it on plastic because Acetone will soften most plastic

Que revelde el muelle buen video❤
now i know who is bidding on the same lenses XD ;)
Hey could you help me repair a Olympus Stylus 1?
Sorry, but I do not have repair service.
mikeno62 that is very sad but maybe you could help me repair it myself if I describe the problem? That would be very helpful!
You should be very welcome to describe the problem.
@@mikeno62 thank you but I found the problem, the LCD was damaged so I ordered a new one from eBay and hopefully I am able to repair it :)
Wow, I actually have the same lens and problem. But this repair seems to be a little too sophisticated for myself.
Thanks a lot for this video!!
Greetings

That's an AI lens, not AI-S
Good catch. The 5 screws in the mount and the DOF scale not engraved on the chrome ring indicate an AI lens. The “Lens Made in Japan” engraving indicate it was the first AI version. (The second AI version has “Made in Japan” engraved).
@@alexblaze8878 Good knowledge!
