​    1975 saw the introduction of the Contax RTS, the first camera since 1961 (when the Contax IIa/IIIa rangefinders were discontinued) to bear that moniker and which was the firstfruits of the technological alliance between Zeiss (owners of the Contax name) and Yashica, the Japanese camera maker (who did the actual manufacturing). The RTS (which stood for Real Time System, to emphasize the supposedly superior responsiveness of the body) was aimed at professionals and serious enthusiasts with pocketbooks sufficiently large to take on the task of mounting pricey Carl Zeiss glass in front of it. The RTS was a success, but as Nikon had found out two decades earlier with the F, having a single model camera lineup that aimed towards the high-end of the SLR market tended to limit opportunities for sales (less cameras sold = less lenses & accessories sold ;-)). So, four years later, in a move that mirrored Nikon's introduction of the enthusiast-oriented Nikkorex F in 1962 (followed by the more-successful Nikkormat of 1965), Contax/Yashica introduced their Contax-badged contender in the very-competitive amateur market. But what does this have to do with the Yashica FX-D? Let's find out :-).
