I found these two brass lens at my usual antique shop. I did a batter trade plus top up for the lenses. I wish to know more about the lenses, for example, which camera bodies it used to mount, the mount, when the lenses made. Thanks

1. Carl Zeiss Jena DDR Tevidon 2/10. Very heavy lens with aperature and focusing rings or mechanisms.

2. Carl Zeiss Jena 1.4,5 F-25cm DRP. This lens got front and rear glasses and the aperature blades sandwiched between them. I think its for the field type camera.

The former is a GDR TV camera lens - some of them are crap, some of them are considered desirable among film students, but I don't know about that particular one. The latter is a 1913 plate camera barrel lens - still ok for large format with a slight vintage look, but at a resolution somewhere in the 10-20lp/mm it is not quite up to hooking it up to 35mm or a even smaller digital sensor unless for special effects.

DDR is Deutsche Demokratische Republik, also known as GDR (German Democratic Republic) or most commonly among English-speakers, East Germany Wink

DRP seems to stand for Deutsches Reichs Patent, or Imperial German Patent - but that's just what Google told me Laughing

Kris,

The Tevidon is a TV lens. As such it has a very very short register distance, it will probably not reach infinity even on a G1-class (micro-4/3) camera.

The only use I can think of for a lens of such short register is to reverse it and use it as a "super macro."

I have a spoiled Pentacon 50mm lens. I removed the front most of the lens of this Pentacon lens and replaced it with CZJ Tessar front lens.



Here are the photos I shot in that combination. The distance for it to focus is very very short.

My dad



And with the Tessar lens itself, hand mounted it on my E-510, its the same for the focusing distance. Very very short too and seems blurry.
