Finally a Rolleiflex SL35 with an unknown 1.4/50mm lens (front ring is missing; lens is probably a Zeiss Planar). I don't know much about German cameras and lenses - but a quick search did come up with only the Zeiss Planar 1.4/50mm as a f1.4 standard lens for the SL35. Sure enough, this one has a differerent optical construction than the contemporary Zeiss Planar 1.4/50mm for the Contax RTS (smaller diamater of the rear lens). Does anyone have more precise information?


This is the standard 7/6 extended Ultron construction (added rear element) like the similar Minolta MD II and III lenses. The first copies have been manufactured in Braunschweig/Germany and later the Production was moved to Singapore. All Singapore models are HFT coated, the first patches made in Germany "only" MC. The markings/branding was "Carl Zeiss Planar" in the Western World and "Opton" in the former Eastern Block countries. There was no Voigtländer branded Version.

Interesting drive for the F2.
I have not seen that battery pack configuration before.
Could you show the rear of the drive when you have time?

Thank you for that information! My lens is marked with "Lens made in West Germany". Interestingly, this Zeiss Planar 1.4/50mm for Rolleiflex clearly has an optical construction differing from the Zeiss Planar 1.4/50mm for Contax/Yashica. While the front looks similar, the rear lens of the Rolleiflex Zeiss 1.4/50 has a much smaller diameter than the rear lens of the Planar 1.4/50 for CY.

Well, that's a rather long and complicated story because Rollei took over Voigtländer/Braunschweig from Zeiss/Oberkochen when Rollei started the 35mm camera and lenses production in Braunschweig.
Prior to this take-over Zeiss branded the Voigtländer developed and manufactured lenses also as Zeiss lenses and they kept also the copyright which later resulted in several lawsuits between Rollei and Zeiss.
Approximately at the same time Zeiss started with their Contax/Yashica cooperation and production with a different line of lenses without Voigtländer history. The HFT and T* coating design was a co-development from Rollei and Zeiss and is identical.
At least this is in short the information as published by Claus Prochnov in his "Report" books about Voigtländer and Rollei; i.e. a rather trustworthy source.

Thanks very much! It is what I thought at first, and probably the final version.
Sorry I missed this. Notifications are not working here?

I received this Petri made Exakta FE 2000, one of the last cameras released by Ihagee West before going out of business for good. It was an M42 mount camera, but this time with an auto-exposure function which worked only with lenses made for this particular camera type. This one arrived with the meter not running, which turned out to be nothing more than a corroded battery connection having broken right through. Unfortunately it was something of a ordeal to reattach it as the metal for the battery connector would not accept solder, regardless of what I tried. I eventually found a solution however. The lens is the Petri 55/1.7, a later upgrade from their standard 55/1.8 lens.

Nikkormat FTn here with Nikon bellows PB-2, 55mm f3.5 Micro-Nikkor P, and early Nikon slide copying unit.
I finally got the lens lock-pin repair completed (by me) on the bellows.



Same bellows with F2, BR-2 Nikkor reversing ring, and reversed 50mm f2 Nikkor H. Good combination for some of the medium and large size insects that spring brings.
