Fix stuck aperture blades on Super Tak?


I have a Super Takumar 200mm that's very sharp wide open. The problem is, it's stuck wide open. Has anyone ever disassembled and repaired stuck blades on a Super Tak 200mm, or does anyone know of an available online guide for doing that?

I'd really like to be able to use this lens, from what I can see using it wide open, it's going to be very sharp stopped down a bit.

If you can't find anything via Google, you might want to join up and post in Maintenance and Repair section in the forum in my sig. I couldn't find anything with a search there, but someone might have taken one apart and not documented it.

i haven't been inside the tak200 but i have been inside the 300. all of these seem to be built to a certain spec. once you get the lens module out there will be an aperture module incased in it. it's a separate unit that i haven't had to breach except in my 500/4.5 and it's fairly simple IF you pay attention. your prob is there is probably oil on the ap blades or there's a small cam lever that sticks thru the module that incases the lenses and engages the ap ring. if you're not mechanically inclined i'd suggest getting it repaired by a pro.. basically it's the same as THIS just bigger.. taking it apart and putting it back together tho takes some forthought..
