Originally posted by Happyman Adam (or others), how does the K-5's AF system compare to that of KP's? I, too, have been considering a new camera, mainly because autofocus has never been something that made me extremely happy about the K-5. For example I had to get rid of the Tamron 17-50 f2.8, because in combination with K-5, it was always hit and miss.
The KP's AF is improved in a number of ways, most notably in that it can focus in -3EV, making it much more sensitive and less prone to hunting in low light.
Of course, it also has 27 points rather than 11, so you get more density, which makes multi-point modes much more useful.
Lastly, improvements have been made to the tracking algorithm, and this dramatically improves the keeper rate when you're shooting bursts of things close to the camera.
Note that the KP shares its AF system with the K-3 II. The K-3's AF is similar but without the tracking enhancements, while the K-5 II's AF still has the improved low-light sensitivity, but only 11 points.
If you're after fast AF, also treat yourself to the 55-300mm PLM lens, as it's insanely quick. Only works with the K-3 or newer, though.
