Hi
I just got a copy of this lens, v2 in canon museum. It is in great shape cosmetically and the glass is clear.
test wide open f/3.5
100% centerish
100% far right
No PP of any kind straight out of camera jpeg
Now f/8 or more
It seems to shoot just great, but I have two questions:
aperture adjustment---no clicks--normal? It moves fine, just does not stop anywhere between wide open and closed.
Focus ring. Turns with out alot of effort, but the resistance varies. This is not happening in any one location and is intermitant. No squeaking.
OK to use it this way? Am I going to hurt the threads on the helicoil?
