As a matter of fact the outer bayonet normals for the Kiev 5 work nicely on every Contax - the limitation is the other way around, inner bayonet normals can't even be attached to a Kiev 5.

The 2.8/35 pre war Biogon and the USSR equivalent Jupiter-12 do not fit the Contax IIa/IIIa, and all Nikon RF normals and long lenses do front focus by about 15% close-up on Contax type cameras - apart from that I am not aware of any incompatibilities within Contax Bayonet cameras.

In any case, Norman seems to be talking of the 50/1.5 Sonnar - whose pre war designed version would be compatible with a Jupiter-3 optical block. The Opton/Oberkochen lens made in Western Germany after 1949 was a redesign with different mechanics and is not parts compatible with the old one and its Ukrainian successor.

And the Jupiter-3 optical block on ebay is of 1984 vintage - right from the years where Kiev quality control was worst. As unused parts generally were rejects even from that overall poor batch, anybody who buys that thing might be in for a true late soviet experience. It probably is worse than the fogged Zeiss it replaces, and will be much harder to clean or repair.

Personally I'd wait for a 50/1.5 Sonnar to come around, or purchase a earlier (fifties to early sixties) Jupiter-3 in full working order.
