Focusing And Locking The Focusing Knob - Mamiya RZ67 Professional Instructions Manual

Focusing and Locking the Focusing Knob

Focusing
Depressing the Cocking Lever sets the mir-
ror. projecting a bright image on the focusing
screen. Focus by rotating to-and-fro either of
the two Focusing Knobs until the image ap-
pears sharp.
Locking the Focusing Knob
After adjusting the focus, focusing deviation
can be prevented by locking the Focusing Knob
with the Focusing Knob Lock Lever, which is
found at the rear of the left-hand Focusing
Knob. Simply raise the lever and push it for-
ward. clamping the Focusing Knob in place.
When working with wide-angle lenses, the
lens can be prefocused at the hyperfocal dis-
tance, and the knob locked with the Focusing
Knob Lock Lever so that snap-shots can freely
be taken without the need of focusing. Exam-
ples of other occasions on which the lock lever
will prove useful include when copying, engag-
ing in macrophotography, or using telephoto
lenses.
