The Contaflex I, launched in 1953, was equipped with a fixed Zeiss Tessar 45 mm f /2.8 lens with front-cell focusing. [2] The earliest Contaflex I cameras had a Synchro-Compur shutter with the old scale of shutter speeds (1-2-5-10-25-50-100-250-500) and no self-timer, but very soon it adopted the new scale 1-2-4-8-15-30-60-125-250-500.
Top view of Bessamatic Deluxe camera with Color-Skopar X lens. The leaf shutter is a Synchro-Compur unit mounted behind the interchangeable lens, which uses the DKL-mount, although lenses made for the Bessamatic are not generally compatible with other DKL-mount cameras, and the Bessamatic DKL-mount will not generally accept non-Voigtländer lenses without physical modifications.

The shutter is a Synchro-Compur behind the lens unit, which is part of the camera body. The aperture is now in the interchangeable lenses, which eliminates the problem of setting the wrong aperture on the original Retina Reflex. Speed are from 1 sec. to 1/500th plus bulb. It features M and X syncs and a self-timer.
Hasselblad 500C (Sweden): replaced the Hasselblad 1600F/1000F's (see above) problematic focal-plane shutter with reliable interlens Synchro-Compur leaf shutters and made the 2 + 1 ⁄ 4 medium format SLR the dominant professional studio camera by the late 1950s. Well-integrated, durable and reliable design without instant return mirror, but ...
A Prontor-Compur connection (also known as a PC connector, PC terminal, or PC socket) is a standard 3.5 mm (1/8") electrical connector (as defined in ISO 519 [1]) used in photography to synchronize the shutter to the flash.
Prominent refers to two distinct lines of rangefinder cameras made by Voigtländer.. The first Prominent, stylized in all-caps as PROMINENT and also known as the Prominent 6×9 to distinguish it from the later camera line, was a folding, fixed-lens rangefinder camera that used 120 film and was first marketed in 1932.
Synchro transmitters and receivers must be powered by the same branch circuit, so to speak; the mains excitation voltage sources must match in voltage and phase. The safest approach is to bus the five or six lines from transmitters and receivers at a common point.
The front element of the Tessar can be replaced to make a long-focus or wide-angle lens. In 1957 Carl Zeiss offered the long-focus Pro Tessar 115 mm f/4 and 85 mm f/4, and the wide-angle Pro Tessar 35 mm f/3,2 for use on the central-shutter SLR Zeiss Ikon Contaflex Super B cameras.
