Got some sun today, and remembered the tripod -- so I was able to get some sharp shots of some little birds. The high resolution of the K20 allows for some pretty extreme crops. These were taken from about 10-12 feet away.
They were cropped to from 1600 to 1850 on the long side at 5x7, then PP'd (mostly to remove CA which wasn't really evident on the full frame, but became really noticeable in the crops) and resized.

Needless to say, I'm pretty pleased with the K20's performance -- the lens combo didn't do too shabbily either.:-)
