Pentax recently launched their new mirror-less APSC camera designed by Australian designer Mark Newson. The story seemed to focus more on the exterior design than the innards of the camera. This is basically a K5, which I own, with an improved processing engine, better video capability, no viewfinder or mirror box. Unlike every other mirror-less camera on the market Pentax decided to keep the K mount and its back focus distance to the sensor, and make the new lenses thinner. This allows regular K mount lenses to be used without an adapter, but means that no rangefinder lenses can be used with this camera. A lot of people on the the various forums thought this was a ridiculous design flaw that Pentax has made. I am not so sure. The other cameras that are on the market with APSC sensors look ridiculous with anything but a regular prime lens, as the lenses dwarf the camera bodies. Pentax K01 keeps the similar body size of the K5 and is better suited to the larger zoom lenses that most people seem to carry. The absence of an EVF is much more of a problem sfor me thant the lack of a shorter flange for the lenses.
As such I think this is a “tripod” camera, and would be a great for astrophotography, given the superb performance of the K5 in this area, the K01 should prove equal or better. It might make a good back up tot he K5. Personally I would like to see a camera shaped more like the K1000 with an EVF and an articulating LCD screen. This would be something I could get more excited about.
