Originally posted by beholder3 I understand what you say, but still I assume a K-3 III would be a very attractive camera at that price point if it was a KP in a K-3 shaped alloy body with 2 card slots, top lcd, without any higher FPS.
Low end FF cameras as you mentioned are in many ways crippled, clunky, cheaply built and require expensive glass for the same tele reach, so they are not necessarily at a advantage competing with fully featured APSC models without those manifold weaknesses.
The breadth of user requirements is large. No single aspect drives a majority.
Frame rate in only one of many metrics that people look at. To me, the most important thing is image quality and that is where the KP and even the K70 seem to have it over the K3 II. They really do seem to have significantly better high iso performance and probably better low iso performance as well. It would be nice to see that come to a semi-pro body for Pentax.
But honestly, if it is priced too low, you won't sell KP cameras and if it is priced too high it won't sell because it is too high. I don't know the market well enough to know what range of specs you would need to justify a given price point, but certainly Ricoh has seemed to be pretty intelligent in where they have priced their cameras and if they aren't selling at a given price point, they are pretty quick to drop the price a little to generate sales.
