Above is an image of a Contax IIIa with turret, and 4
lenses:
Carl Zeis Jena Nr.1422xxx Tessar
1:8 f=2.8CM (circa 1934)
Carl Zeis Jena Nr.1983xxx Sonnar
1:1.5 f=5CM (circa 1932)
Carl Zeis Jena Nr.2139xxx Sonnar
1:2 f=8.5CM (circa1936)
Carl Zeis Jena Nr.1692xxx Sonnar
1:4 f=13.5CM (circa 1937)
Carl Zeis Jena Nr.1735xxx Sonnar
6.3 f=18CM (circa 1937)
(not shown)
The
equipment is not really in collector condition but it all works and the
glass is free of haze and dust. For some reason, polished metal lenses
show signs of wear much more easily than modern composite lenses. Now
I have an appreciation of why these types of metal lenses in perfect
condition demand such high prices.
