Most optical houses have marketed microscope objectives for use in
microphotography. Leitz produced a wide range of these, for instance, in
their Micro-Summars, Milars, and Photars; B&L, Nikon, and Rodenstock have
also sold the like. These lenses will normally provide coverage up to 4"by
5" plates. Rollei sold an adapter to use these lenses on the SL66 cameras
and Hasselblad did the same for their 2000 series cameras, while Leica
sells one for their R cameras.
Carl Zeiss Jena produced a range of such lenses in their Mikrotar line.
The first such lens was the 1.6/1cm Mikrotar introduced in teh 1930's.
This lens would allow 7:1 photography and higher ratios. The complete set,
incidentally, consisted of:
1cm f/1.6 Mikotar, Carl Zeiss Jena catalogue number 11 21 46
Mikrotar adapter for the Contax, Zeiss Ikon catalogue number 5522/9
Microscope slide adapter, Zeiss Ikon catalogue number 5522/11
Zeiss 10X loupe, Zeiss Ikon catalogue number 1293
Weight offset ring, Zeiss Ikon catalogue number 5522/17
One odd thing about these lenses is that both Leitz and Zeiss marketed
through their microscope divisions and not through the camera side of the
house. Thus, you bought a Leitz Photar from a dealer stocking the Leitz
scientific gear and the camera on which to use it from a Leica camera dealer.
After the end of the Second World War, Carl Zeiss Jena expanded the scope
of their offerings to a full range of Mikrotars. In the 1960's, Carl
Zeiss, the West German guys, brought out their superb Luminar series, while
Leitz upgraded their offerings to their fine Luminar line.
These lenses, being by heritage microscope objectives, normally come in the
so-called "Royal Screw", the standard microscope objective thread-size
adopted in 1868 by the Royal Microscope Society. This is 0.7965" (20.1mm)
x 36 turns per inch Whitworth. Some of the larger lenses employ
proprietary thread sizes. The f/6.3 100mm Carl Zeiss Luminar comes in a
35mm thread mount ONLY used on the adapters for the Contarex bellows, and
these adapters (two are necessary) are quite rarely found.
I have a bunch of Mikrotars, Luminars, Micro-Summars, Micro-Tessars,
Milars, and Photars. I normally use them on my Hasselblad 2000 FCM or on a
Visoflex rig on my Leica M6.
