I'm stumped by this lens. The best schematic I can get is: http://www.taunusreiter.de/Cameras/FDold85mmf18_.gif I need to get at the rear of the third-to-front element to clean off some fungus. So I bought me a spanner and took off the first retaining ring to see this: http://forums.dpreview.com/files/t/TS560x560~834fc919c6b943e6a8508211867ffd3e I popped the front-most element out onto my palm and see this: http://forums.dpreview.com/files/t/TS560x560~fb777f304a4c41dc90b168086650aba2 The C-ring looks like it is holding the second and third element in so I remove the C-ring. But the second and third elements don't pop out like the first element. Anyone have any idea what I could try? Thanks!!!
