The Mamiya Press is a medium format rangefinder camera system designed to accept interchangeable backs and lenses.

mamiya made a number of variants to the basic body design, including one model, the 600SE,

that was licensed to be marketed under the polariod
name. The camera body itself is a simple affair,

with a single-window
combined range- and view-finder that couples to the lens for focusing.


It has tripod mounts in both vertical and horizontal positions, a mount
for a handgrip for the left hand,

and cold shoes on both the body and
the handgrip.

The lens system incorporates a breechlock mount unique to the Mamiya Press,

and each lens is mounted in a seikosha leaf shutter.
Lenses of fixed focal lengths from 50mm to 250mm were produced,

 all of
which covered up to 2x3 film sheets,

while the 127mm and 75mm lenses
offered greater coverage necessary for the 2 7/8 x 3 3/4 inch images
produced by the Polaroid backs.

Lenses produced were:

• 50mm f/6.3 - 8 elements in 5 groups (Biogon type)
• 65mm f/6.3 - 4 elements in 4 groups (similar to the Wide Field Ektars or Bausch & Lomb Metrogon)
• 75mm f/5.6 - 7 elements in 4 groups (Biogon type)
• 90mm f/3.5 - 4 elements in 3 groups (Tessar type)
• 100mm f/3.5 - 4 elements in 3 groups (Tessar type)
• 100mm f/2.8 - 6 elements in 4 groups (Gauss type)
• 127mm f/4.7 - 4 elements in 3 groups (Tessar type)
• 150mm f/5.6 - 4 elements in 3 groups (Tessar type)
• 250mm f/8 (not rangefinder coupled)
• 250mm f/5 - 6 elements in 4 groups (Sonnar type)

Two different types of back exist for the Mamiya Press, the Graflex
back, and the Mamiya Back, or G-type and M-types.
The backs are
incompatible with each other, and Press cameras came in versions for
either one back or the other.
The Super 23 only accepted Mamiya (M-type)
backs.
The Mamiya Universal had interchangeable rear adapters - the M
adapter and the G adapter.
Thus, the Universal was capable of using both
Mamiya and Graflex backs, as long as one had the appropriate adapter.

The Universal also accepted a Polaroid back; this needed no adapter and
attached directly to the main camera body.
Mamiya film backs include 6x9, 6x7, a combination 6x4.5-6x6-6x9
back, and Polaroid packfilm backs.
Accessory backs for 2.5 x 3.5 inch
(6.5x9cm) sheet film and plates include a right angle focusing back,
a
magnifying focusing back and a ground glass viewing back. Other
accessories include a wire frame sportsfinder,
separate finders for the
50mm, 65mm, and 75mm lenses, back spacers and extension tubes.

This was the first iteration of the camera. It lacked brightlines in
the finder, came standard with a 90mm f/3.5 lens,
and was produced with a
M-type back. Other models were produced, such as the Press G, with the Graflex back system,
and the Press S with a fixed 105mm lens.

This upgraded version was capable of using roll film and 2x3 sheet
film,
and came with a rear tilt and swing device to allow for close
focus and tilt effects.
It also added a brightline display to the
finder, with automatic parallax compensation,
and framelines for 100mm,
150mm, and 250mm lenses. 

mamiya universal
This revision allowed for use of both Mamiya and Graflex backs, as
well as the Rand Polaroid back,
but eliminated the Super 23's rear
bellows device. A similar model was marketed as the polariod 600se,

however both the lens mount, and film back mounts, were changed so that
neither lenses nor film backs
were interchangeable between the Polaroid
and Mamiya models. Some 3rd party companies in Japan & the US

produced adapters to allow Mamiya Press back accessories to be fitted to
the 600SE.
