Pentax 6x7 - Vertical Camera Mounting Procedures

telephoto lenses, a firm , sturdy tripod should
be used.
Blur
is most pronounced at shutter speeds
between 1/
60 and 1/ 4 sec. When using long
telephotos at these speeds, attach a
tripod
firmly to the tripod mount as shown in Photo
B.
Even better results will be assured if a
second
tripod is attached to the camera body.
6 x 7 cameras
with a mirror -lock feature
should be used
with the mirror locked up to
further reduce the possibility of blur.
Mounting the Camera Vertically: To shoot
with the camera in vertical position, slightly
loosen
the fastener ring shown in Photo C and
position it so
that the white dot is at a 90-
degree angle. Then, insert the lens mount into
the camera mount , making sure the bayonet
tabs insert
properly . Once inserted, tighten
the fastener ring by turning it to the left if you
are behind
the camera. Check that the bayonet
has locked
properly before letting go of the
camera (Photo D) .
