Special Care of Lenses

Changing Lens

The lens mounting flange of the Canon 7 is equipped with both the
Canon standard screw-in-mount and Canon special bayonet-mount M.
To detach a screw-in-type lens (other than the F 0.95 50mm lens) from
the camera, hold the lens barrel at its base and turn counter-clockwise
(
illustrated by small arrow). To replace a lens, keep lens cap on but
remove the dust cap from the lens. Turn the lens first counter-clockwise
for half a turn to insure that the lens threads and the camera mounting
flange do not cross. Next, turn clockwise (illustrated by large arrow) until
the lens is securely in place.
When mounting or dismounting a lens of 85mm or greater focal
length, be sure to set it at the nearest footage setting.
To detach a special bayonet-
mount-M-type lens from the
camera, turn the bayonet
tightening ring counterclockwise
(illustrated by small arrow) . . . then the lens can be pulled out. To fit the
lens into position, match the red mark of the tightening ring to the pin on the
lens barrel. Insert the pin of the lens into the hole on the lens mounting
flange . . . and turn the tightening ring clockwise (illustrated by large arrow)
while pushing in the lens.
