I've had several Contax cameras, including a Contax II, Contax III, and Contax IIIa. I agree with previous statements that the Contax is built to a MUCH higher set of quality standards. Where you see maching marks on a Kiev, you see nice, smooth surfaces on the Contax. I'm not saying that the Kiev is shoddily built as a general rule, just that the Contax is generally a better built camera. In addition to the Contax II I currently have (I sold the Contax III and IIIa a while back) I use a Kiev 4a and "No-Name" Kiev. The "No-Name" is an very nice camera, well finished, and with a smooth winding and focusing action. However, this camera was used very little, and is in excellent condition. My 4a is rather ugly, but it has been CLA'd recently, and though not as smooth in focusing or winding as the "No-Name", it still works great and takes fantastic pictures. The Carl Zeiss Sonnar that originally came with the "No-Name" does perform better than the Jupiter-8 on the Kiev, but the difference isn't significant. Currently, my Contax II is out for repair, and after it is returned, I'll have about $300 invested in it. I bought my CLA'd 4a with the 50mm J-8, 35mm J-12 w/ finder, and 85mm J-9 w/ finder, all for $150. Bang for the buck? You bet!
