shake reduction the pentax-developed shake reduction technology solves one of the oldest photographic problems blur caused by handheld camera shake the k10d produces sharp photos in challenging situations without having to use a tripod hand-held photography is now possible with long telephoto lenses or when long exposure times are required due to poor lighting the pentax shake reduction system is integrated into the camera body and is independent of the lens in use the principle behind its operation is simple movement sensors in the body recognize camera shake the system ensures that at the moment of exposure the compensating movement of the ccd sensor provides blur-free pictures the advantage is obvious you can increase your hand-held shooting by 2.5 to 4 stops if you are intentionally moving the camera when shooting ­ while panning with a formula 1 race car along the track for example ­ you can simply deactivate the shake reduction system pentax has filed for over 30 patents for this sr system which uses a ball-bearing-mounted oscillator unit with four electromagnets that position the free-floating image sensor angular velocity sensors detect camera movement and relay the amount of compensation necessary to the electromagnets that move the sensor to compensate for any shake the shake reduction unit consists of the rear bearing plate the central plate containing the ccd and controlling electromagnets and the front plate containing the permanent magnets.
