Magnifying focusing back
This device enables ob-
serving the image on the
ground glass from the right-
angle direction against the
optical axis. The right-angle
magnifier can be very
simply turned upward or
sideward, facilitating focus-
ing from any camera angle.
This back is provided
with an eye-level, totally
enclosed box instead of the
right-angle magnifier of the
right-angle focusing back.
Precise focusing is possible
by directly observing the
image on the ground glass
focusing screen through the
eyepiece magnifier.
Since a Fresnel lens is used on both focusing backs, the entire
ground glass is very bright, and focusing can be easily accomplished
because extraneous light is blocked out. The ground glass has light
lines which indicate a 6 x 7 format.
After focusing, insert a cut film/plate holder as well as the focusing
screen holder for photographing.
Attaching and Detaching the Right-angle Magnifier
The right-angle magnifier can be removed by swinging it around the
bottom of the housing while depressing the button of the right-angle
magnifier.
To attach the right-angle magnifier, match the projections at the
bottom of the magnifier to the holes of the holder, and press in the
upper part. When attaching the magnifier, the button does not need to
be pressed.
The right-angle magnifier can be attached for up, down, right, and
left directions. Merely attach it in the direction necessary for the camera
angle employed.
When looking from above or below, the image assumes the correct
right-side-up position, but the right and left will be reversed. When
looking from the side
,
right and left are correct but the image will be
upside down.
