I bought a Pentax H1 and lenses from a nice older guy and can't figure out what the mounts are for the Schneider Curtagon 35mm 2.8 and Tele-Xenar 135mm 3.5.
They work fine as a M42 mount, but there is more mechanism there that I have not been able to find any information on. Both aperture and shutter speed are adjustable on the camera body and it looks like they have an window and cam mechanism to transmit the information back to the camera body. There is a ring that rotates about 90 degrees that sits flush with the mating surface of the M42 mount.
The guy I bought it from said he picked it up while stationed in Turkey in about 1963. That was all he could tell me about it though.
Any ideas? Thanks,
Andy |

Whoa, never seen one of them. But my best guess is it came off an old Exacta.

Thanks Br,
So it is a lens with a built in light meter (missing) that mounts on M42. In my search for info I had seen these but didn't put together that is what it was. |

An overly complicated solution, more of an 'add on' than a 'built in' and the Weston Master III or IV would give far more accurate and useable readings for the professional of the day. Never really sure where they thought the market would be for this contraption - optically you could not fault them, however, the high cost pushed them out of the reach of all but the very deep pocketed amateur and the limited light reading ability of the meters did not endear them to the professional. Thank heavens the 'Spotmatic' appeared when it did. Although on that subject, the TTL system in the original Praktica Mat could give far superior results under certain lighting conditions. Sadly, the East German ethos of building down to a price produced quirky mechanisms and strange faults which condemned the camera to oblivion. Still my lump, one of two purchased by the Company in 1966, still produces images that are on a par with any TTL body that uses film as its medium. |
