and 70mm film.
The film holders and back adapters are very easily exchanged.
10. Unique mirror shockless mechanism
By adopting a unique centrifuged friction governor system, the
mirror functions smoothly without sensing shocks. Mirror shock,
constituting the most important problem involved in large, single-
lens reflex cameras, has been solved.
11. Large variety of finders
A big selection of finders conforming to your photographic ob-
jective are available.
They include a CdS finder (appropriate exposure obtainable with
Through-the-lens measuring system), a Prism finder (subjects can be
seen as an erect image), a CdS prism finder (former two types of
finders are combined). a Magnifying hood (easily visible and bright),
a Dual magnifying hood (performs precision focusing by speedily
changing the magnifier of high magnification), and a Universal
sportsfinder (permits focusing on the focusing screen after it has
been installed).
The focusing screens are also easily exchangeable. Depending
on the photographing objectives, a checker, a rangefinder spot, a
microprism, and a cross-hair can be selected at your option.
12. Excellent heat- and cold-resistant capacity
Camera component parts are capable of demonstrating their
functions within a wide temperature range from approximately 120°F
to -
to -
The lens-shutter maintains accurate function, even in severe cold,
and shutter speed deviation is negligible. Its resistivity to coldness
is superb.
Although the camera operating unit grows sluggish at or below
C), it is sufficiently capable of operating the camera until
the temperature drops to approximately - 50° F
C).
13. Mirror-up photography (independent mirror release)
possible
When sharp pictures are demanded, the mirror-up mechanism
plays a big role. When taking a picture unhurriedly with the camera
mounted on a tripod. or when photographing at slow shutter speeds
or using a telephoto lens, the mirror-up operation merit is highly
effective.
