[5] The original line of Press cameras (1960–66) were equipped with a reverse Galilean viewfinder that had a magnification of 0.66× and an effective rangefinder baseline length of 60 mm (2.4 in).

[6] The upgraded rangefinder introduced with the Super 23 (1967) and Universal (1969) models had a magnification of 0.72× with a slightly increased effective baseline length of 61.2 mm (2.41 in).

[7] In addition, the upgraded rangefinder had switchable brightline frames corresponding to the 100, 150, and 250 mm lenses, which automatically corrected for parallax.

[1]: 130 The Press G, introduced in November 1963,[1]: 132  is identical to the original except for the G-type (Graflok) back attachment system, which is compatible with the same interface used by Graflex Speed Graphic cameras.

It features a fixed Mamiya Color Sekor 105 mm f/3.5 lens with four elements in three groups and does not have a rear bellows, but accepts the same rollfilm backs as the Press using a M-type interface.

Externally, the top cover of the Standard has a satin chrome finish (instead of grey paint) and the body is colored black; the name is printed on the front of the camera near the rangefinder window.

[15] The final model was introduced in April 1969 and was produced until 1991;[1]: 132  it was an update of the Standard 23, also omitting the rear bellows but equipped with the same viewfinder as the Super 23.

The 600/SE are limited to using Polaroid Type 100 pack film through a removable back that is not compatible with the Mamiya P-type interface on the Universal.

[4] In addition, there is a set of two spacers (60453) available for the Universal that extend the back away from the body, equivalent to the close-up capability enabled by the rear bellows on the Super 23.

[2]: 32–33 [4] On the Universal, a Tetraphoto (four-photo) or Duophoto (two-photo) adapter can be added to the front of the lens to capture multiple images simultaneously on Polaroid film.
