I frequently suffer from buyer's remorse. On receiving a new camera the first thing I do is test it - usually in far from optimal conditions - to look for reasons to kick myself over the purchase. My feeling is that the images here probably lack a bit of punch and sharpness because it's a drab day with low light levels, and pictures taken side by side with the Kr would not look much different. There may also be a few in-camera tweaks which need to be made in the first few weeks of getting to know a camera - NR, image settings etc.
Perhaps this is nearest the truth plus a bit of handshake with the excitement of having a K30.
Anyway I've put in the hard miles tonight with some proper testing and my initial feeling is that things are ok.
Initially I got some better hand held shots indoor with the flash. I thought that was because I had turned all NR off from "auto". Later testing proved it made little difference anyway. So I did the testing with the DFA 100mm Maacro WR and the 300mm DA* which was close to min focusing distance. I stuck a test sheet on the wall and mounted the camera on the tripod, used 160 ISO, bounce flash to start. All shot in raw with the 2 sec timer, autofocused but switched across to manual before releasing shutter to prevent any minor focus readjustments. Used f4.5 for the 300mm and a range of apertures with the 100mm.
All results seemed good. I then tried some shots with the 300mm at 2000 ISO in raw with and without ISO NR. I couldn't really see any difference and nor could I when I repeated it in JPG. I then checked the SR by taking with and without handheld shots at 1/15th sec with the 100mm. Again a clear improvement with SR. Did a small sharpen after resizing to get back to raw. My main observation is that it is possible that the K-r does a bit more to the raw files than the K-30 because I noticed a bigger improvement with basic auto processing for contrast, sharpening etc.
Now back to the real world and hopefully some light to see what happens!
Obviously I can't put the 50 odd pics on here but out of embarrassment and respect for attempts to put my mind at rest I'll put a few on.

I use this shot a lot for testing and the edges are usually razor sharp. It is giving the green light and focus bleep and there's not much to confuse it here either.
