This is from all the reviews I've read a great camera, I've used a few Pentax systems in the past and found them very good.

The Pentax K-01 is designed with incumbent Pentax users in mind. While it is still a mirrorless camera, the K0-1 can fit the standard K-Mount lenses you already have. The 16 Megapixel sensor is APS-C sized—larger than a typical Hybrid camera— which produces fantastic image qualities at high ISO levels. The inbuilt HDR feature lets you get the most from your photos without necessarily turning on the computer, and is accessible from the top dial along with auto modes and manual settings. The K01 comes with Full High Definition which can be fully taken advantage of thanks to the array of Pentax lenses at your disposal.
