Spent a day with the family there before school starts again. I took with me the K5, 18-135, 15, 31, and 200. Ended up mostly shooting with the zoom and 200. Wish I had more time there.
One thing was obvious--the RAW files from the K5 are very impressive, even at high ISO. Further, I really like the color output from the sensor. Reminds me a little of the Sigma DP1/2, sort of pastel like without being unsaturated (hard to explain).
All taken with the 18-135
