Over several years I had no issues with the 139 and 137, but the RTS I was horrible and after a while I learned that mine was unfixable and I got my money back. The first RTS ended up with a poor reputation. The RTS II fared better, but I can't speak about that model from experience. I haven't heard anything negative about later Contax models, particularly the 167MT which I did feel some interest for at one stage, but did nothing about. But considering their age (I had mine in the early 80s-early 90s) I'd be a bit cautious about buying an early model now. But I still think the Zeiss lenses are a strong incentive to consider Contax. Good luck with your journey.
RTS I naming is wrong confusing. Its RTS. like RX and RXII(no focus-aid here).
it has no ceramics-filmpressure plate like someone is telling. ST like RTS III have.
