Aperture Ring.

Turns out the aperture ring on the 50mm lens that is on the Canon AV-1 that my papa gave to me last night is broken and stuck at f1.8 and last night me and my dad decided to try and fix it. So taking it apart was the easy job and then there was a lot of putting it back together and trying but nothing seemed to be working so we decided just to put it back together and just run it wide open all the time. But last night we couldn't get it back together, so now it's lying on the table downstairs in pieces until my dad gets in from work to give it another go!
