pentax shake reduction the pentax k100d digital slr incorporates a unique shake reduction feature that helps deliver sharp blur-free handheld shots with any pentax slr lens this is particularly helpful in situations where camera shake is an issue such as with telephoto lenses indoors without a flash or other low light conditions such as at dawn dusk or at night the pentax shake reduction sr feature is an electromagnetically controlled system built into the body to detect handheld camera shake and compensates by moving a free floating image sensor unlike other dslr optical anti-shake systems this sr system delivers shake reduction with all pentax slr lenses ever manufactured without requiring a special series of bulky expensive optics over 30 patents have been filed 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 as a result photographers can capture sharp images at a shutter speed that is 2 to 3.5 stops slower e.g 1/15 sec instead of 1/60 sec with a standard lens than would otherwise be possible the sr system provides a crucial advantage when shooting handheld with telephoto or tele-zoom lenses at macro distances or any other situation that magnifies the effects of camera shake the sr system also helps considerably when taking non-flash pictures indoors or at dusk or other low light situations without using a tripod based on a free-floating sensor design pentax sr is superior to other sensor-moving systems because it uses no guide rails allowing the sensor to oscillate at a quicker response time.
