Cleaning Nikkor PC 85 aperture blades ? any guide ?

[hans voralberg]

Well, mine has oil on the blades and kinda sticky between f2 towards f4, which is quite annoying. But I have no idea how to reach the blades to clean them, cause I cant figure out how to dissemble the lens.

I tried all the screws on the outer barrel, doesnt seems to do anything useful, I'm thinking that the way in might be through the retention ring on top of the front element, but if there's a guide I'd love to have a look before exploring 😀

It's quite simple, if it's a chrome one. See here for more details:

hey Roland,
Does the 50/1.4 follow this same sort of path for disassembly?

The 5cm F1.4 has a retaining ring on the rear. Undo it to take out the optics module. The optics module unscrews by hand into sections.

Thanks Brian.
