Flash Photography
The Mamiya 7 features an X synchro
flash terminal and its lens shutter system
permits flash synchronization at all
shutter speeds.
Shoe-mounted flash units can be
attached directly to the hot-shoe, while
flash brackets can be attached to the
tripod socket for larger flash guns.
Remove safety cover to attach sync cord
to PC terminal on front left bottom of
camera.

CAUTION:
When an electronic flash is connected
to the hot-shoe, current moves through
the X contact. So, be sure to put the
safety cover supplied with the camera
on the X contact so that you will not
receive an electric shock.
When using infrared film, it is necessary
to make a focusing adjustment in order to
achieve accurate focus. This is because
the focus position of the image deviates
from normal since the infrared ray
wavelength is longer. After focusing in the
usual manner, check the distance on the
distance scale that is aligned with the
center reference mark of the lens. Make
the focusing adjustment by turning the
focusing ring in the direction of the arrow
in the accompanying photograph so that
the distance just observed is aligned with
the infrared mark.
[Determining the aperture]
When using automatic flash units, refer to
the instructions on the flash unit for
correct aperture settings.
When using a manual electronic flash,
the guide number divided by subject
distance gives the correct aperture.
*Charged electronic flash units
sometimes fire when they are attached to
the camera. This does not indicate a
defective circuit.
*When using electronic flash, be sure to
read its manual carefully.
*Be careful, if electronic flash is used at
the "A" (Auto exposure) mode, over-
exposure may occur.
Infrared Photography
When using infrared film, be sure to
read the instructions with the film.
