Originally posted by csa I shoot right in my back yard, for birds, wildlife.
My most common subject too.
Once I got a KP, I found I wasn't using my K-3 much so I sold it. I agree with others that the KP's superior ISO performance gives an extra 1.5-2 EV stops, which is just invaluable for wildlife (especially with a slow aperture lens like the DA 55-300 PLM).
I shoot a lot at 3200 ISO
And can go higher when necessary (6400 ISO)
The AF is better too. I also like the tilt screen for tripod shots and for high or low handheld shots and the third wheel is really handy.
I preferred the ergonomics of the K-3 (e.g. the grip and the placement of the AE-L-AF button), and the burst rate and battery life are superior. But they don't make up for the IQ advantages of the KP and the other features I have mentioned.
