Dismounting
1. Turn the Breech-lock ring counterclock
wise until it stops.
2.
Pull the lens out from the camera body.
When removing a lens, take special care not
to damage the protruding pins and levers on
the rear. With the exception of the Fish-eye
7.5mm lens, always put a lens down with
the rear facing up.
For more information on general use and
care of the lens, please see the lens instruc
tion booklet.
Note
Since the following two FL lenses might cause
damage to the camera, they cannot be mounted
on the AV-1:
FL19mm f/3.5, FL58mm f/1.2.
The following two F L lenses may be mounted,
but, for technical reasons the camera's built-in
meter becomes unreliable and is unusable:
FL35mm f/2.5, FL50mm f/1.8.
One of these lenses may be mounted only
after the film has been completely advanced.
