Rollei Carl Zeiss Rolleiflex SL35 Qbm Tele-Tessar F4 200mm

Rolleiflex SL35 manufactured by Rollei introduced yet another bayonet mount when launched in 1970. This bayonet mount was used on all Rollei’s 35mm SLRs, and on most of the Voigtländer VSL models. It is sometimes called QBM for Quick Bayonet Mount.
There were three versions of the lens mount. The first lenses for the SL35 had only one pin for the automatic diaphragm preselecting. With the introduction of the SL350, a new cam was added to transmit the selected aperture to the body for the open-aperture metering. Later, with the introduction of the SL2000F and SL3003, another cam was added to permit the display of the aperture in the viewfinder. The older lenses can mount on the newer bodies, but they do not activate the new features. The older bodies can accept the newer lenses transparently.
The lenses produced in that mount were mostly from Carl Zeiss and were of high quality. Some of these lenses had begun their career as Contarex lenses, and most of the range was to be recycled as Contax/Yashica lenses. Some of the Zeiss lenses were sold under the Voigtländer name to go with the VSL range.
There were two variations of the barrel, the older lenses (one-pin and two-pin lenses) had an all metal finish on the focusing ring, the later ones (two-pin and three-pin lenses) had a rubberized focusing ring. The Voigtländer name variant only existed with two pins, in the old finish. At some point Zeiss introduced the HFT multicoating in all the lens range.
This Tele–Tessar is a rare lens to find and is a fast 200mm lens. With superb quality lenses
