Most of the photography I do is Landscape photography, with the shooting of local events and bands from time to time, and the K-3 works very well for me in this regard.
Not bashing other brands in any way, but my selection of my first Pentax was after a review of many factors and narrowing it down between a couple of cameras. When I went and tried the two I was considering, the Pentax just felt better in my hands, and that was my final factor in making a decision.
