Canon 35mm f2 Disassembly?

[PatrickCheung]

Hey guys!

Someone tampered with my beloved 35/2 when I was out for dinner (gotta be more careful with my stuff...) and the aperture now only stops down to f4... but the aperture ring is misaligned and f2 reads as f11, f2.8 as f16, and f4 as f22.

There's a local repairman who could fix the issue, but I also don't have much time to visit him... and I need the lens back in a week, before I leave for Hong Kong for the next four months. I figure I'd give it a shot, as it's quite a beater lens anyway.

Does anyone have any experience with disassembling the 35/2, or is there a manual out there? If so... can anyone give me some tips as to how to start/what to avoid? I've only ever opened up and "worked on" J8's following Brian Sweeney's instructions...

Thanks 🙂
Patrick

Partial disassmbling is easy -

Just unscrew the lens from its back like it is shown at last figure and here you are. Be careful and mark the mutial positions of all parts!

These photos are for 50/1.8 but I disassembled mine 35/1.8 and everythig was the same. So I think that it will be the same for 35/2
