I was just recently given a nikkor 600mm graphic arts lens that the previous owner just had no further use for. the aperture blades in the lens are coated in rust, and are out of the track or whatever mechanism holds them.
it will not open up or stop down any more than the current stuck phase.
the smaller coupled lens seems to have a special pattern in the blades, so I was hoping someone either knew the pattern or could point me to a repair guide.
about half the blades are not connected at both ends, and all are jammed up in the center of the lens.
oh, and there is this little metal lever that seems like it should adjust the aperture, but it just moves freely. I can see it rotating a ring inside the lens, but nothing happens. is it supposed to link to something?
thanks in advance.
actually, one other question-might i just be better off scrapping the current aperture mount and attaching this lens to a shutter?
thanks again.
