[Largeformat] Lens info
Does anyone know of a good web site for looking up comparative stats on
older lenses?
What I have is a Carl Zeiss Jena Tessar f/6.3 165mm, and I'm curious.
And, while I'm asking... What do the initials DRP stand for? On the lens
barrel, in addition to what appears to be the serial number [Nr. 166752],
there is another designation: DRP 142294. Is that a German patent number?
