My K-3 and K-1 keep me quite busy. There's no "waiting" around my house. When the new APS_c flagship comes out I'll give it a look but there's no guarantee I'll buy. What I have doesn't let me down very often.
K-3 images from the last week....
AF problem? What AF problem? Any "problems i had with these and most of my images are not related to Pentax AF.
I simply don't understand why people wait if they really need better AF. It's simple matter of buying camera for the AF you need. The odds of Pentax matching what Canon and Nikon have to offer is so remote as to non-existent. And there are good AF bodies for relatively cheap these days, OK, not cheap compared to a K-70, but good AF doesn't comer cheap, from any manufacturer.
