I am selling a Zeiss Jena 3.5cm F2.8 Biogon for the Contax II, III, or Kiev rangefinder cameras. This is the coated ("red-T") post-war Jena version of the Biogon with a rear element featuring a protective ring. The condition is reasonably good for a lens of this vintage. There are many micro coating scratches on the front element and some internal edge haze. The rear element is very clean.
I think the overall glass aspect is fairly clear however, and it will shoot well if not used closely into the Sun. Because of the condition I am selling the lens "as-is", with no returns. Note that this lens will not fit the Contax IIa or IIIa (post-war models of the Contax). I have set quite an attractive price because I know someone here will make great use of it!
