Just posted: our sixteen-page Pentax K-01 review. In the third of our collaborative reviews with the Digital Camera Resource Page's Jeff Keller, we look at Pentax's first large-sensor mirrorless camera, the 16MP APS-C K-01. The K-01 is unusual for a mirrorless camera in that it uses a preexisting lens mount - so it has to be the same depth as a DSLR, despite the lack of mirror. The idiosyncratic approach is emphasized by the camera's unconventional styling by designer Marc Newson, but what's the K-01 like to use, when you get past its looks?

The use of the full-depth K-mount means the camera is immediately compatible with the many K lenses made Pentax and other brands over the decades. However, this added depth limits the options for adapting other lenses, as is popular with other mirrorless systems.

This review is based on one originally published at the Digital Camera Resource Page, enhanced with a full set of our own product images, our usual studio comparisons and an expanded samples gallery, plus the addition of a standard dpreview score.
