Canon V - Manual (Page 36)

All Canon Cameras and Lenses feature standard flanges and threads. The screw-in
lens mount has been proven the most accurate and durable, with the greatest area
of lens-to-camera contact of any type of camera connection.
To change your lens, place the Lens Cap over the top of the lens. Grip the lens
barrel at its base and apply gentle pressure until the lens is loose. Continue turning
until the lens is completely unscrewed. Be sure that the camera (when loaded with
film) is in shade and be sure to cover the lens base with a Dust Cap as soon as
possible. Any Canon Lens will couple with the Model V camera.
To replace lens, keep Lens Cap on the lens but remove Base Cap. Turn the lens
first in a counter-clockwise direction for half a turn. This makes sure that the lens
threads and the camera mount flanges do not cross. Next, turn in a clockwise direc­
tion until the lens is securely in place. Do not force the lens any further.
Always tighten a lens by its base, not by the top. If the lens has a Lens Focusing
Lever (11) be sure this is in the locked (“ ) position.
Note: When mounting or removing any lens of 85mm or greater focal length, be
certain you have lens set at nearest footage setting to protect camera, range­
finder and actuating mechanism.
