My RTSIII is working fine... Use it mainly to take slides when I travel. The build of the camera is great but the controls are not that intuitive.
The different brands of cameras are built for different consumer class in mind lah. I don't see how you are going to use a Contax to take quality picture for fast-paced sports etc etc. Not impossible to get great pictures, but just a bit more difficult. Even the most-skilled photographers are going to have trouble lah. Having superior image quality is pointless unless you can get the opportunity to take the pictures first.Technology just make this window of opportunity easier to catch.Can't really compare like that lah.
