I have been using Pentax cameras continuously for more than twenty-five years, and I am heavily invested in Pentax glass--new and old. (In addition to my many Pentax lenses , I own four Zeiss ZK and three Voigtlanders.) Hence I have a vested interest in the success of Pentax and the K mount. It would be a very expensive proposition for me to 'jump ship.' Still.... if Pentax continues in the direction it is currently going, this might make sense for me.
I have stayed with Pentax because I believed that they would (eventually) produce a full-frame camera that would be in line with their traditional design philosophy. This would mean a small, tough camera with lots lots of high quality primes.
To some extent, Pentax has done this. They have made very rugged cameras with the K-7 and K-5, and their primes are (generally speaking) quite good. However, the K-5 (I sent mine back after a couple weeks) has actually done little to advance the cause. It is, let's be frank, just another consumer APS-C offering--and one with more than its share of problems. There is no sign of a FF on the horizon; and in terms of 'cutting edge' technolgy, Pentax simply has not kept up with the competition.
So now what? Sony has produced in the NEX-5N a camera that is, in most respects, a K-5 at half the cost (and which is smaller and which will take different brands of lenses). It also has focus technology (auto and manual) that is far ahead of Pentax's. The NEX-7 ups the ante even more.
If I were to purchase a new camera tomorrow, I doubt it would be a K-5 (or any Pentax). And iIf I am going to be stuck with APS-C, Sony now appears to be the better choice. I'll still hang on to my K mount lenses. However, my own postion regarding Pentax-Richoh has become one of 'wait and see'.
