I have always felt that the Contax was like an air-cooled Porsche 911, just a hell of a great performing and feeling ride. You get the feeling of having some modern comforts such as AF,Metering, winder, etc., but still have the manual feeling of setting the aperture on the lens itself, not via a knob or wheel.It also just has that solid feel like older Hasselblads with the Zeiss lenses and build quality. Yeah back in the day it's specs were very respectable, but today they are not at the top compared to the newer technology dependent cars and out they are out of production, but are still running and producing great images.
Did not have much experience with the Rollei but it had a great feeling as well, but was bulkier and did not have a great deal of digital options back then.
The H series, Hy6 and Phamiya are all great systems, but lack the feel of the these cameras.
Hey if you do not need all the bells and whistles of the newer bodies the Contax works very well and there are some good deals out there on new and used ones. I would recommend picking up a second body and if you see an accessory that you think you may like, buy it now because it may not be there later.
