manual aperture on canon fd adapter/work around doesnt work

[Mirrorkisser]

Hi,

i cant get the manual aperture to work. I followed the steps in a guide, where i had to push in the pins and and move the inside of the lens clock wise. That all worked fine. Now i can change the aperture on the lens. But i cant mount it to my camera anymore.

I can just do that, once i move the inside of the lens counter-clockwise again. Then i can change the aperture though.

Any help highly appreciated

I found out something weird: sometimes, when i do the routine with the 2 pins the manual aperture works after mounting the lens to my camera. Then when i unmount it and mount it again, it does not work again.

Could the adapter be faulty?

ok, apparently it is the ciecio adapter. depending on the angle i put the lens on it, sometimes manual aperture works, sometimes not. Maybe the stopper is too short or something...


ok, its a bit tricky, but now i found the perfect angle to put the lens on the adapter and now it almost always works...
