Lightweight, Waist Level Finder N

The waist level finder hood can be opened and closed
with a single action. Lifting the magnifier upright com­pletely seals the hood, making the viewfinder ideal for
outdoor photography, close-ups and copying. The
sports finder which is located outside the hood is con­venient for fast action photography.

The prism finder is well-suited for action photography

providing an unreversed, eye-level image. Horizontal or

AE Prism Finder N features 3-way metering which
can automatically switch from center-weighted averag­ing metering for general photography, to spot metering

according to photographic conditions. These metering
systems facilitate AE Photography under difficult

conditions, such as adverse lighting. Further a

Depth-of-field refers to the total area
(foreground and background) which
will appear in sharp focus. The area of
sharpness (depth-of-field) depends
upon the distance the lens is focused
at, the f/stop (or aperture) being used,
and the focal length of the lens.
The area that will appear sharp can be
determined

as follows:

24

1. Depth-of-field can be determined
by

referring

to the Depth-of-field
Scale engraved on the lens.
For example, with the 60mm

lens focused at 10 ft. (3m) and
Aperture Ring set to f/22, the

When the camera is not used for a long period of time,
remove the battery and any film from the camera.
Avoid storing the camera for prolonged periods of time in a
damp or salty atmosphere. (Color film should be stored at
the manufacturer’s recommended temperatures,)
Since cameras are precision instruments, avoid shocks
and rough handling.
When the camera is stored for a long time, periodically
remove the camera and release the shutter several times
to keep the camera in good condition.

Cleaning:

Never touch the lens or mirror surfaces. When your camera
is contaminated with dust, fingerprints and so on, blow
away the dust particles with a blower, and clean the lens

surface with lens cleaning tissue and lens cleaner. Merely

blowing dust particles off the mirror surface is
never touch the mirror.

Periodic Check:

Periodically check the camera to make sure that it is in
working order. This is especially important before a photo­graphic assignment. (Check the battery, flash synchroniza-

tion, mirror and shutter movement, film wind, diaphragm

automation and so on.)

If the camera is malfunctioning, take it to the nearest

authorized Mamiya Service Center for repairs.
