The 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 Voigtl?nder VSL models. This lens mount 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 preselection. 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 Yashica / Contax lenses. Some of the Zeiss lenses were sold under the Voigtl?nder 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 Voigtl?nder name variant only existed with two pins, in the old finish.
At some point Zeiss introduced the HFT multicoating in all the lens range.
List of the Zeiss lenses, and Voigtl?nder equivalents:
At the beginning of the SL35 career, a limited range of lenses were made by Schneider. These lenses only existed in one-pin version, and they have a finish quite similar to the first Zeiss lenses.
It seems that at least two of the Schneider M42 lenses (type IIIb) were made in very limited numbers in QBM mount:[2]
35/2.8 Curtagon
50/1.9 Xenon
Later, Schneider also manufactured two special perspective control shift lenses. They have no diaphragm automation, and have their own finish.
28/2.8 PC-Super Angulon, special shift lens
35/4 PC-Curtagon, special shift lens
Rolleinar
A more economical range called Rolleinar was manufactured mostly by Mamiya and were mostly of reputable quality too. They were also sold under the Voigtl?nder name, with AR indicating a Rolleinar origin.
