Mamiya M645 1000S Digital Camera User Manual


 
If the indicator needle cannot be cen-
tered even after rotating the aperture
ring as far as it will go, the exposure
must be adjusted by rotating the CdS
Prism Finder shutter speed dial. If the
indicator needle is too high, set the
shutter speed dial to a shorter (“faster”)
speed; it too low, set to a longer
(“slower”) speed. After adjusting the
shutter speed dial of the
CdS
Prism
Finder, if the indicator needle is slightly
off-center, make final adjustments with
the aperture ring.
Whenever changing the setting of the
shutter speed dial of the CdS Prism
Finder to adjust for exposure, do not
forget to set the shutter speed dial of
the camera body to the same setting.

The brackets visible in the viewfinder
not only indicate correct exposure, but
are also notched to indicate *2 f/stops
(see diagram) to simplify exposure
compensation for unusual lighting.

to OFF, the indicator needle rests at
