Mamiya RB67 - 25

• 120 Roll Film Holder 6 x 4.5
The operating method is the sama as the
6 x 7 roll film holder , except for the following
instructions.
Field of View
A field of view for the 6 x 4.5 format and
the
format direction can be ascertained
through the finder mask and format index
mark on the roll film holder.
Attaching the Finder Mask
1. Remove the focusing hood from the
camera body .
2.
Slightly curve up the finder mask by
bearing on the lugs on the mask with the
finger tips ; then insert the four corners of
the mask under the leaf springs on the
focusing screen frame as shown in the
photo.
Attach the mask so that the triangular
hole is positioned on the upper, left corner,
viewed from the camera rear. This hole
gives access to reading the exposure meter
needle when the CdS Finder is attached .
3. Reattach the focusing hood.
Horizontal and Vertical Format Marks
When using this roll film holder, distinction
between a horizontal and vertical format to
be photographed is made by the format
marks on the upper side or the left side on
the
holder (instead of the marks for 6 x 7
format on the revolving adapter). The area
to be photographed can be distinguished
by the finder mask as shown in the photos.
In addition, when viewed from the rear
side , the frame on the back cover -
symbolized by a 6 x 4.5 format - indicates
direction of the format in accordance with
revolving the back.
