Common Sense Camera Care and Practice
The Mamiya 7 is a precision optical/mechanical
instrument, built for heavy professional use and a
long service life, if properly treated and maintained.
Please observe these basic caveats:
• Read instructions before using camera.
• Protect camera against shocks and falls. Use
neckstrap supplied with it, whenever possible.
• Check the battery frequently and always carry
spares. The sealed battery supplied with the
camera may have been subject to storage
conditions which have reduced its service life.
• Be sure to wipe battery contacts before installation
and watch correct polarity.
• Battery life differs, depending on frequency of use,
type, age, storage condition, ambient temperature
(use External Battery Case in very cold weather),
etc.
• Always remove the battery (and film) when camera
is not used for a period of time.
• Always keep covers on lenses and camera body.
• Do not store the camera at temperatures exceeding 40°C
(105° F) and -10°C (15°F). Also avoid humid or sea air
environment.
• Prolonged disuse shortens camera life. Periodically exercise
the shutter (at different speeds, lens diaphragms and
focusing mounts.
• Protect camera against rain and moisture.
• Do not touch lens surfaces. Use blower or lens tissue to
remove dust particles.
Specific Suggestions:
• Operate the film advance lever with easy strokes. If moved
too rapidly it may affect spacing.
• Hold lens focusing mounts on bottom in order not to block
range finder window.
• Always test your equipment before going on important
assignments.
