Mamiya PRO 645 - Manual (Page 4)

3 x More Negative Area Than the 35mm Format
Plus Superior Image Quality From Mamiya World-
Class Lenses
The 6x4.5cm format offers approx. 3 times more image
area than the 35mm (24x36mm) format, Man’s vision is
horizontal and rectangular.
Film Holders are rectangular and so are most pictures in
them. The 6x4.5 format is also large enough to be viewed
without a magnifier and its aspect ratio (horizontal / vertical)
is ideal, requiring minimum cropping. Mamiya’s high
performance medium format lenses assure sharpness
and beautiful color fidelity.

Sturdy, Versatile, Safe and Highly Reliable Body
- Tailored to Satisfy Pro Needs -
Introduced in 1975 to not only provide an alternative to
the 35mm format, but to afford the user with advanced
versatility given its much larger format, the Mamiya 645
Series is constantly being upgraded. Elements such as
speed and handling plus a host of other special features
have been enhanced to satisfy the needs of most de-
manding professionals.
Two new convenient safety features have been added to
the 645 PRO in the form of state-of-the-art optoelectronics
which immediately identifies problems with the shutter
(i.e. when it will not release) when the AE Prism Finder
FE401 is used. Whether these malfunctions develop from
failure to draw out the Dark Slide, or if there are problems
in film take-up, the LED will indicate the source of the
trouble. With these new advancements, Mamiya believes
the most demanding pro will be more than satisfied with
the new edition 645.
Enhanced Interchangeable Roll Film Holder System

- Enables Polaroid and Even 35mm Panoramic
Photography -
The 645 PRO features an interchangeable film holder
system capable of using a far wider range of roll film
holders than before. Depending on the application, the
system can be quickly attached to or detached from the
camera, ensuring the ability to catch even fast changing
scenes. It also features fail-safe devices including, for
example, one that warns when you have failed to take out
the dark slide when the AE Prism Finder FE401 is being
used.
