Contax N Digital review
Considering this camera has two year old technology and being the 1st full frame dSLR, it is a great camera even in today standard for image quality. You cannot expect to use it to shoot fast action sport as Contax's market is more for artists. It is a great gear if you like Carl Zeiss lenses, and image quality is superb when you shoot RAW format and develop in CS.
useable ISO from 25-200. Small buffer size.
