Originally posted by DogLover I seriously cannot imagine anyone who has actually used a K5 saying such a thing. It is so much of an improvement over the K7 that the matter is not even debatable. Before I got one, I too thought that it would be kind of a "K7 with faster AF and better high-ISO performance." I've even said as much in previous posts. Boy, was I wrong. K5 is not a "progression camera" as you say, it is a smack-in-the-head game changer, and yes, a truly great camera!
BTW, K7 was a leap over the K20 really only in design, not so much in performance. K20 was a progression from the K10, since you apparently have trouble grasping what progression means.
Yes, you could say that the K5 is what the K7 should have been, but guess what, the sensor in the K5 didn't exist when the K7 came out. Hell, the K5 is what the K10 should have been! Makes about as much sense. Your "logic" and assessment of Pentax makes my head hurt.
This is clearly not about grasping what progress means. You have to go way beyond that. If you are stuck there, much like the person who is worried about if I could afford K-5, you are not even at a point of being right or wrong.
While I believe that improved sensor in this day and age will not make photographer much better, I do believe that improved design and ergonomics will go a mile and half in making one a better photographer. To me this is more of a factor than a sensor can ever be, because many and much of the sensors on the market these days are more or less all superior than yesteryears. A better designed camera will allow a photographer to be more in control of the equipment. K-7's design I thought was very intuitive for a camera of that size and where you can go with it.
Pentax took a chance when selecting Samsung sensor for K-7. They in a way looked at sensors as like lenses. They thought that sensors that simulated the attractive characteristics of films would be a hit amongst Pentaxian. They went retro with appearance to be in line with that concept. They were clearly excited about the camera. They spent considerably more resources on advertising pre-release. But they were wrong. People wanted sensors that are more in line with the rest of the market. It clearly did not exceed the pre release expectations sales wise. So for majority of the market, K-5 was pretty much what K-7 should have been. I am sure that there were sensors at the time of K-7 release that behaved better in DxO labs. It was a tactical error from the market standpoint.
I for one love the characteristics of K-7 sensor. I think that K-7 is a very under-rated camera. A fantastic design, as you say, and much agreed. Therefore, to me, K-7 is fine the way it is. The only limitation for me was that when printing large, results were not what I was looking for. That is really about it.
