I have no further information on these lenses.
Panagor made an automatic 2× converter in the
Pentacon Six mount. One experienced user describes it as
being of “amateur quality”.
For a review of this converter, see the Lens Test section. To go to the lens test section, click here.
This was one of the great German (1945-1990, West German) photographic lens manufacturers, although the company now mainly specialises in lenses for spectacles (reading glasses). Its photographic lenses have a high reputation for the quality of the images that they can produce. The lenses that they made available for medium format cameras, including the Pentacon Six, were part of their “Imagon” range, which were essentially designed as portrait lenses, for use principally in a studio situation. Further details are now located here.
In January 2015 I received a report that the lens
manufacturer Steinheil of Munich, in West Germany (as it was at that time) offered two
lenses with the Praktisix mount, an f/2.8/135mm lens, first
manufactured with this mount in 1957 and an f/4.5/200mm lens
first manufactured with this mount in 1958. According to
Clément Aguila and Michel Rouah, in their book "Exakta
Collection", there were Steinheil lenses with these
specifications in the Steinheil catalogue from 1953 and 1956,
respectively, with the Exakta 35mm camera mount. For the
longer focal lengths on 35mm cameras, lens manufacturers
frequently provided suitable mounts for lenses that were
originally designed to cover medium format cameras, so the
lenses with these focal lengths listed by Aguila and Rouah may
have been previously designed for other (medium format)
cameras, and may be the same ones that were subsequently
offered for the Praktisix. If these are the same lenses,
then the details would be as follows (as taken from Aguila and
|First offered for
Exakta 35mm cameras
Of course, I cannot at this point in time guarantee that the details given in this chart do indeed correspond to the Steinheil lenses that were offered in the Praktisix mount. Furthermore, the fact that a manufacturer offered in its catalogue lenses of a given focal length in a particular camera mount is no guarantee that such combinations of lens and mount were ever manufactured and sold.
Auto Tele Converter 2x
This was apparently at times marketed in the USA. It appears to be a re-labelled Panagor converter.
AUTO KINOTELEX 2x converter
This was a German brand name apparently applied principally to re-badged items from other manufacturers. It appears to be a re-labelled Panagor converter.
It is reasonably easy to adapt other lenses to fit the Pentacon Six – at least if one does not include auto aperture control – and other manufacturers may have offered their lenses in the Pentacon Six mount. I personally doubt if many of these lenses were available from stock in the Pentacon Six mount, and some of them may have never been produced in this mount.
For the same reason, it is possible to modify some medium-format lenses and almost any large-format lens for use on a Pentacon Six or Praktisix, and occasionally such privately-modified lenses appear. It is obviously not possible to provide data on such lenses.
This data is based on published sources and information from a collector, to whom I express my thanks.
