Mamiya C

Unlike most TLR cameras, the Mamiya C has interchangeable lenses. The upper and lower lenses come off as a unit, and are available in at least seven different focal lengths. The lower lens of each unit has an aperture diaphragm as well as a leaf shutter. A flash sync terminal is part of the lens unit, and the delay can be set to M or X mode. The camera has an interlocking baffle that enables lenses to be changed without exposing the film.

Focusing is performed via a bellows system on the front side of the camera. Early models had separate film advance and shutter cocking mechanisms; on later models the shutter was automatically cocked as the film was advanced. There is no metering in the camera body, so an external light meter is necessary; later models were compatible with optional accessory viewfinders that had built-in meters.

While the basic shape remained the same, the bodies increased with size over time. Two of the early models were branded with "Mamiyaflex" on the nameplate attached to the viewfinder; all of the other C series cameras were branded with "Mamiya". The first in the C series, the Mamiyaflex C, was introduced in 1957 as a follow-on to the earlier Mamiyaflex line, which had included the Automat A (1949) and Automat B (1954); the primary innovation of the C was the introduction of an interchangeable lens mount. The Mamiyaflex C was accompanied with 80mm, 105mm, and 135mm lenses.{{cite report |url=https://www.pacificrimcamera.com/rl/00330/00330.pdf |title=Mamiya C Professional |date=November 1973 |publisher=Mamiya Camera Co., Ltd. |website=Pacific Rim Camera, Reference Library |accessdate=2 June 2020}}{{rp|26}} The C2 was introduced in June 1958 and is distinguished from its predecessor with a second focusing knob on the left side of the camera. In addition, two more lenses (65mm, 180mm) joined the line.{{rp|26}}

The "Mamiyaflex" name was dropped for "Mamiya" when the C3 was introduced in February 1962; the C3 featured updated styling, adding the name above the lens mount and switching to a gray leather body covering. At this time, the lenses used a new shutter mechanism with a faster minimum speed.{{rp|26}} The C3 also moved to a crank for film advance, speeding up camera operation.

The line was split in the mid-1960s with the C33 (April 1965) and C22 (March 1966) models. C22 had fewer features, which also made it lighter than the C33.{{rp|26–27}} The main distinguishing feature was the C33 had more automated operation, where winding the film also cocked the shutter automatically;{{cite web |url=https://www.pacificrimcamera.com/rl/01532/01532.pdf |title=Mamiya C33 |publisher=Ehrenreich Photo-Optical Industries, Inc. |website=Pacific Rim Camera, Reference Library |accessdate=2 June 2020}} the C22 required two separate actions.{{cite web |url=https://www.pacificrimcamera.com/rl/01531/01531.pdf |title=Mamiya C22 |publisher=Ehrenreich Photo-Optical Industries, Inc. |website=Pacific Rim Camera, Reference Library |accessdate=2 June 2020}} Both were the first Mamiya C TLRs that were able to use 220 film, but a different back was required.{{rp|26–27}}

The C220 (April 1968) and C330 (October 1969) models were developed from the C22 and C33, respectively, with updated styling (the prominent nameplate now had chrome lettering on black) and a built-in switchable pressure plate to enable the use of 220 film.{{rp|27}} Weight was reduced as well. The final two lenses (55mm and 250mm) also were introduced at about this time.{{cite web |url=https://www.pacificrimcamera.com/rl/01380/01380.pdf |title=Mamiya C220 |publisher=Ehrenreich Photo-Optical Industries, Inc. |website=Pacific Rim Camera, Reference Library |accessdate=2 June 2020}}{{cite web |url=https://www.pacificrimcamera.com/rl/01378/01378.pdf |title=Mamiya C330 |publisher=Ehrenreich Photo-Optical Industries, Inc. |website=Pacific Rim Camera, Reference Library |accessdate=2 June 2020}}

The later C330f, C220f, and C330S were refined versions of their respective base cameras, and carried the letter annotation on a nameplate below the lens mount. One of the changes from the C330 to the C330f, for example, was the inclusion of a focusing track lock on the latter.{{cite web |url=https://www.pacificrimcamera.com/rl/01379/01379.pdf |title=Mamiya C330f C220 Professional |date=July 1975 |publisher=Bell & Howell / Mamiya Company |website=Pacific Rim Camera, Reference Library |accessdate=2 June 2020}}

Lenses for the Mamiya C series have been grouped by users into three different series based on the shutter model and the color of the shutter housing: first chrome, second chrome, and black. Most lenses can be used on most bodies, but some combinations won't allow for automatic shutter cocking. The first chrome series had Seikosha-MX shutters with speeds from 1 s to {{frac|400}} s. The second chrome series had Seikosha-S shutters with speeds from 1 s to {{frac|500}} s, plus Bulb. A few chrome shutter lens had a Seikosha-SLV shutter. The black series had Seiko shutters, except for the 80 mm {{f/}}3.7 lens, which had a Copal shutter.
