Shutter Speed
The Mamiya 7 has an aperture-priority,
AE lens shutter. Once the aperture and
film speed are set, the AE meter selects
a proper shutter speed in relation to the
set aperture.
In the manual photographic mode,
proper shutter speed is indicated by a
blinking red LED within the viewfinder.
1. To set the diaphragm to a desired
aperture, rotate the aperture ring “A”
until the appropriate figure is aligned with
the central red index line “B” (Click stops
are provided at each engraved aperture
number but the diaphragm can be set
also for intermediate stops.)
[Determining the shutter speed]
2. Rotate the shutter speed dial and
select either the A(Auto exposure) or
manual mode for photographing.
Rotate the dial to align it with the white
index line (-) on the camera body.
* At A or AEL, the dial is locked. The lock
can be released by pressing the AE lock
release button “A” in the center of dial.
* In any position other than A or AEL, the
shutter speed dial is in the manual mode
and moves freely from click-stop to
click-stop: it must be set on a specific
click-stop and cannot be used at an in
between setting.
* Intermediate Diaphragm settings
(between click stops) are possible
Intermediate Shutter Speeds (between
engraved numbers) are not possible.
Shutter speed dial:
A. (Automatic exposure)
Based on the aperture setting, the
camera automatically selects the
shutter speed.
AEL.(AE lock)
The camera memorizes the aperture
when shutter release button is
touched slightly so that, even when
the position of the subject or camera
changes, a picture can be taken with
the initial aperture setting and is not
affected by changes in light
conditions or subject contrast.
B. (Bulb exposure)
At this position, the shutter will remain
open as long as the shutter release
button is pressed.
Shutter controls
On the shutter speed dial the yellow
numbers indicate the number of
whole seconds while the white
numbers indicate fractions of
seconds.
Example: "4" indicates 4 seconds
while 125 indicates 1/125 seconds.
