Mount the Lens onto the Camera
Position the lens in the camera's bayonet mount so
that the mounting indexes on lens and camera body
are aligned. Taking care not to press the lens release
button, twist lens counterclockwise until it locks into
place.
To remove: Push the lens release button (8) and turn
the lens mounting ring clockwise until the lens
comes off.
Note: When changing lenses with fiim loaded in the
camera, be careful not to expose the mirror box to
direct sunlight.
If the tripod has a large head, contact between the
lens barrel and the head may make it impossible to
turn the lens aperture ring. In this case, use the
special tripod adapter supplied with the camera
between the tripod head and the camera body.
