Default Canon AE-1 Program Lens Stuck

Thanks, but the whole lens body turns with the ring on this lens.
Wikipedia informs me that this is the "New FD" mount, but should
still work with the AE-1 (as it did before it got stuck).

I realize I'm a little late with this reply, but sometimes the simple
answer is the correct one. The new FD lens differs from the old
lens in that the new FD has a button on the lens ring that must
be depressed to remove the lens. You probably know this,
but still...

Thanks. I do have a Canon lens with such a button, but this one
is without one. The only button is one on the appature ring
which has to be pressed before moving the appature control

Oh dear, I can't spell aperture it seems...

to automatic mode. In case I'm loosing it I just gave it a try,
but it doesn't help.

Actually, after working it a bit, the lens ring does rotate about
1mm against the lens body (the entine lens body rotating about
10mm on the camera's lens mount). The degree of rotation that the
ring has seems unaffected by the romoval of the (previously
tightened) screw that goes into it on the outside.

Perhaps I didn't mount it by turning the whole lens as I remember,
or perhaps the ring was jammed and turning the whole lens to mount
it was the fatal mistake, or maybe the ring is meant to be fixed
in place and is just a little loose.

Actually, if I turn the lens leftwards on the mount and set the
aperture to the maximum f stop (F22, it won't move over to the auto
position), it won't rotate back near as far to the right. If I push
it, the aperture ring stays stationary and changes setting as the
lens rotates (which sets it to about F8). So it seems that the
aperture lever that connects with the camera is caught somewhere.

I'll have a closer look when I have more time.
