 HOW TO CHANGE YOUR LENS
(1) REMOVTNG THE LENS
Turn the Lens [t4ount Ring in a counter-clockwise direction
until the red mark appears on top of the lens barrel. The
lens can then be removed from the camera.
(2) TNSERTING THE LENS
Line up the red dot on the camera body with that on the
lens mount ring. Then insert the lens making sure that
the protruding lock on the bayonet mount of the lens is
on the top. When the lens is in position, turn the lens
mount ring tightly in a clockwise direction.

.HOw TO USE THE PRESET DIAPHRAGM

turn the preset ring clockwise (to the end) ani the dia'
phragm opens fully for viewing and focusing.

anti-clockwise direction until the green mark on the preset
ring lines up with that on the diaphragm ring. (For fully
automatic diaphragms, refer to the Instruction Book for

AHOw TO READ THE DEPTH.OF.FIELD SCALE
The depth-of-fleld scale is engraved on the lens barrel and
 indicated in black lines spreading out on both sides of the
 index marker at the centre. Simply focus the lens in the
normal way, and each pair of black lines which points to
the Diaphragm Scale indicates the depth-of-fleld zone cor-
responding to the diaphragm you set.
For example, the depth-of-field zone for the 35mm lens
 is indicated as follows: When the focusing distance  is
 10 feet (3m) and f/8 is selected, one of black lines at f/8
 points to approximately 6 feet (1.8m), the nearest point
 still in focus and the other points to 30 feet (10m) on
the other side, being the furthest distance in focus. See
 illustration.
