I'm at the clinic but this is what I found in the K-30 materials (and this goes for the K-5 as well as I recall) I had on this computer:
PENTAX Shake Reduction (SR) mechanism for sharp, blur free images
The PENTAX K-30 incorporates the PENTAX-developed SR mechanism, which effectively reduces blur due to camera shake by approximately four shutter steps. Usable with all PENTAX compatible lenses*, including those produced for film format SLR cameras, this mechanism produces sharp, blur free images even under demanding conditions that are prone to camera shake, such as when using a telephoto lens, shooting in the dark without flash illumination, or capturing landscapes in twilight.
The K-30's SR system also offers several other useful features to assist the photographer during shooting, including an Automatic Horizon Correction function to assure high precision image framing and effortless adjustment of horizontal alignment, a Composition Adjustment function to allow minute adjustments of image alignment horizontally/vertically/axially, and an ASTROTRACER mode to eliminate light trails during astronomical photography in combination with the optional O-GPS1 GPS Unit (available separately).
