Mamiya Professional C220 - Changing Lenses; Lens Removal Procedure; Attaching a Lens; Lens Change Precautions

@ Changing Lenses
Turn the focusing knob (8) and
retract the bellows so that the lens
catch (22) moves closest to the body.
Turn the lens change knob (21)
counterclockwise until the word UN-
LOCK appears in the window.
Tip the camera so that the lens
faces upward and, while firmly grasp-
ing the lens barrel, pinch the head
of the lens catch, press the head
toward the camera body, push it down
to release the lens catch, and remove
the lens. To attach another lens to
the camera body, hook the lens catch
as it was, and turn the lens change
knob until the lens locks in place.
PRECAUTIONS
While the word UNLOCK appears in
the window of the lens change knob, |
the portion to which the taking lens
is attached is protected by a cover
from the camera interior to shield
the film from exposure to light, and
a red warning signal is visible on
the ground glass focusing screen.
Should this cover be pushed pur-
posely or inadvertently while the
lens is removed, light will strike the
film. NEVER PUSH IT!
After: changing a lens, turn the
lens change knob (21) until the word
LOCK appears in the window ; other-
wise, the shutter release button
cannot be pressed.
