The Pentax K10D and similar Samsung GX-10 are 10.2-megapixel digital single-lens reflex cameras launched in late 2006.

[6] The K10D has been hailed by Popular Photography and Imaging magazine as "an all-star player,"[7] and was named as a finalist for their 2007 "Camera of the Year" award.

[9] 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,[10] 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.

Like the full-featured KAF2 mount, this has power contacts for the lens and supports power zoom and MTF information transferred from the lens to the body, but lacks the mechanical stop-down coupler necessary for full compatibility with the oldest Pentax K-mount lenses.

[18] Pentax later announced on 14 June, 2007, the introduction of a limited edition K10D package in commemoration of winning of the Japanese Camera Grand Prix.

[20] The K10D won American Photo's Editor's Choice 2007 for the Advanced Digital SLR category.
