Originally posted by tibbitts I believe the aperture control issue has been fixed, but don't think you'll find universal agreement that the KP is K-3 (or even K-5) build quality.
I find very little lacking in the KP build quality. Features (card slots, buffer, top lcd display, frame rate) is another story, but build quality, I don't see any downgrading compared to the K3 I sold.
Responsiveness, stability are better than at least my former K3, which I can only describe as buggy, and as I handle the KP exclusively with the batterygrip attached, I don't think it handles any worse on my DA560, than the K3 did. I dó miss the 100% zoom level of the K3 though: with the KP, there is no 100% setting or indication.
Things like the infamous mirror rattling, but also random lock-ups when stressing the AF, or sub-par AF with a half depleted battery, all made me more and more wary of the K3, and took the enjoyment out of using it. It's a sigh of relief to find that the KP does not (so far) seem to suffer from these quirks, and seems a very stable and responsive camera, which also drives my DA560 better (faster and less hunting).
So all in all, what is K-3 "build quality" actually worth in terms of performance and reliability, and in what way is it better than the KP? I wouldn't know... In fact, I would say the opposite.
