To remove the lens from the camera, press the lens re- lease button and, holding the button depressed, twist the lens to the right as far as it will go . The lens will come loose and can be lifted out.

To mount a lens, position it in the camera's bayonet mount so that the mounting index on the lens and the camera are aligned; then, twist the lens counterclockwise until it clicks and locks into place. While mounting the lens, shade the camera from the sun with your body.

In order to measure exposure at fu II aperture with lenses

having different maximum apertures, the meter must be indexed with the maximum aperture setting of the lens in use. This must be done each time a lens is mounted, as follows: After locking the lens in place, turn the aper- ture ring all the way to the minimum aperture setting, then all the way in the opposite direction. Th is step automatically fits the coupling pin of the Photomic finder into the coupling prong on the lens and adjusts the meter to the maximum aperture ofthe lens.
