I've previously posted samples of the effectiveness of the shake reduction system on the K100D. Here's a sample of the K10D's SR system at work. Image shot hand held with a 200mm lens at f/2.8; 1/20 sec; ISO 200. The original image was shot in RAW. I used the camera's "digital filters" to process the RAW into a JPEG. Then I processed the JPEG into BW to show this detailed crop.
