1 Be sure to unlock the meter circuit switch lock. If
* the meter circuit switch is pressed or is locked, the
red dot appears inside the camera mount. The pre-set
aperture pin, at the back end of the lens, cannot be
connected to the coupling part on the camera body and
the pre-set aperture will not function.
Q Remove the lens from the camera body by turning
^ the bayonet ring of the lens to the left until the red
dot on the lens coincides with the red dot on the camera
mount.
Q Mount the lens by matching the red dot of the lens
^ to the red dot on the camera mount. Turn the bayo¬
net ring to the right and fasten. Before mounting, turn
the bayonet ring of the lens sufficiently to the left and
align the red dot and guide pin of the lens.
■ Attach the lens quickly in the shade. The film will
sometimes become foggy if the lens is left unattached.
■ Whenever a lens is removed, be sure to put on its
dust cap to protect the aperture pin.
■ When not in use for a long time, protect the mirror
with a flange cap.
