Great video cleaning the aperture blades on this lense but my problem is fungus underneath the outer element on this lense. How to seperate the top 2 glass elements for cleaning.
Could you ever show how to clean out a Nikkor 105mm 2.5 AIS? I have one that has a fair bit of dust on some of the elements in front of the aperture blades and I'd love to clean it out.
Thank's Per The dentist tool's are named "ZENITH" number 10 that i use A LOT have a flat end's but different angle's in both end's. Number 11, I also use A LOT has a very sharp point in one end and the other is just a little thicker point. Cheers
I need some help with a Nikkor 105 f2.5 witch needs cleaning and the focus ring is stuck in infinity. And also information on how to open a Nikkor-H Auto 28 f 3.5, thanks for any help you can give me.
I succeded in moving the focus ring, but the outer ring screw is damaged, and I finished damaging it more. I'm thinking in drilling it out with a 1.5mm drill and finding a way to set a new screw afterwards. What do you advise?
I succeded in drilling out the damaged screw and to take of the outer ring. I cleaned the lenses and now I'm going to deal with the helicoil. Up to now all is going well, later I'll deal with making a new thread for the new ring screw. Thanks.
Hi Carlos (and other's), I have just made a film about "how to Re-grease my old Nikkor 105mm 1:2.5. I will show how to fully disassemble the focus helicoid's, then re-lube (re-grease) the helicoid thread's and then assemble it again back to normal. I will upload the film as soon as posible. Cheers Kenneth
Hi and thank you for oyur videos! Is there any way to diassemble front group? I have fungus under front lens, it seems that front group can be disassembled but i can't unsrew it even with big force applied.
+Oleg X. In some Nikon lenses they use some thread lock that was really hard to unscrew and maybe it's the same in this lens. But when I get my hands on one of this lens I will make a film about it. Cheers Kenneth
