SLR cameras from Rolleiflex

The Rolleiflex SL35 is a range of SLR cameras manufactured and sold by the German camera maker Rollei from 1970 to 1982. This range of cameras uses 35mm film. The camera bodies were initially made in Germany. After Zeiss Ikon discontinued camera production, Rollei acquired the Voigtländer brand and camera designs in 1972, and began producing a second generation of SLR cameras in Singapore starting from 1976. Some of those second generation cameras were rebranded and marketed as Voigtländer VSL. The Rolleiflex SL35 line uses QBM (Quick Bayonet Mount) mount, with a flange focal distance of 44.5 mm. The QBM was re used by Rollei for the Rolleiflex SL 2000 F (1981) and successor 3003 (1985), which were modular 135 film SLR cameras similar in concept and execution to contemporary Hasselblad V system and Rolleiflex SL66/6006 cameras.

The Rolleiflex SL35 was a line of 35mm SLR cameras which were developed and built by Rollei from the 1970s until the 1990s. The first camera in the range was the SL35, released in 1970 as the first 35mm SLR produced by Rollei. Compared to its competitors at that time, it was relatively small and light. The Rolleiflex SL35 was the second Rollei SLR camera to be equipped with Carl Zeiss lenses, after the SL66 of 1966. Lenses were designed by Zeiss and manufactured by Rollei under license with Rollei's High Fidelity Transfer (HFT) multicoating as an alternative to the Zeiss T* process. As initially introduced, the SL35 also was available with Schneider Kreuznach lenses as a less expensive alternative. An adapter for automatic diaphragm M42 lens mount interchangeable lenses for Praktica and Pentax was available as an accessory for photographers migrating from the earlier system. After the Zeiss Ikon camera company declared bankruptcy in the early 1970s, Rollei acquired the Voigtländer brand in 1972 along with several camera designs, including the SL 706, an M42 lens mount camera that was derived from the earlier Icarex 35S and was intended to unify the diverse SLR lines offered by Zeiss Ikon. The SL 706 was produced for only one year and is not commonly found. Two years later, in 1974, Rollei produced the Rolleiflex SL350. Compared to the original SL35, the Rolleiflex SL350 had open aperture metering; the earlier Rolleiflex SL35 was built with a stop down light meter, which required the photographer to take an extra step and close the aperture to take an appropriate meter reading. A mechanical connector was added to the QBM lens mount to enable the fully automatic aperture; some early lenses for the SL35 lacked this additional interface and must be stopped down to meter with newer bodies.

In 1976, Rollei introduced its second generation models, the SL35M and SL35ME. These used a visibly different body based on the earlier Icarex 35S / SL 706 design but with plastic top and baseplates and offered nothing technologically radical. The SL35M was a fully mechanical (aside from the meter) camera equivalent to the SL350; the viewfinder offered aperture and metering information, but not shutter speed. which was offered with both M42 and QBM lens mounts. by comparison, the SL35 M and ME weighed A nearly identical body, sharing most components from the same production lines, was sold by Voigtländer as the VSL 3E; they shared the same QBM lens mount, so lenses and bodies from both ranges could be used interchangeably. The SL35 E used a vertical travel bladed metal shutter which was designed for the SL2000.

A whole range of lenses were made for the QBM interchangeable lens mount system fitted to the Rolleiflex SL35 and Voigtländer VSL series cameras. Lens brands manufactured for the QBM system included German made Carl Zeiss, Rollei, Rolleinar, Schneider, and Voigtländer.
