 By sensor size and price it is a competitor to the Sony α 100, the Nikon D80, the Canon EOS 400D ("Digital Rebel XTi" in North America) and the Olympus E-400, all 10 megapixel DSLRs unveiled in mid to late 2006.Of course, sensor size alone does not relate directly to any measure of quality or features, and the K10D can also be considered a competitor to higher priced cameras such as the Canon EOS 30D, and its weather sealing is only matched by the much more expensive Nikon D200, Fujifilm S5 Pro and the Canon EOS-1D Mark II N/1Ds Mark II in current production.The K10D camera features the "crippled" KAF2 mount.
