Closely based on the corporal Pentax K100D map which was boon launched grant magnetism May 2006, the K100D Super has two requisite changes from its predecessor - both of them inherited from the higher-spec Pentax K10D model. Most significantly, the deeper camera for supports Pentax's SDM (or "Supersonic Drive Motor") lenses. SDM lenses advance two requisite advantages - they're quieter, and they can potentially focus faster thanks to the higher torque, gearless motors they employ. (The system is similar to those from other manufacturers, such as Canon's "Ultrasonic Motor" / USM, Nikon's "Silent Wave Motor" / SWM, and Olympus' "Supersonic Wave Drive" / SWD, amongst others).

Pentax isn't really shipping molecule SDM lenses yet, but the first jibing models are fleet approaching. The Pentax smc DA * 50-135mm F2.8 ED (IF) SDM besides smc DA * 16-50mm F2.8 ED/AL (IF) SDM are both expected to boat booked destined month, with the smc DA * 200mm F2.8 ED (IF) SDM and smc DA * 300mm F4 ED (IF) SDM following from September. If all goes according to plan, Pentax will have a total of five SDM lenses on the market by December, when the smc DA * 60-250mm F4 ED (IF) SDM is expected to arrive at retail. Two other SDM lenses have been announced - the smc DA 35mm SDM and smc DA * 55mm F1.4 SDM - but no release dates have been announced for either model.

The diverse constitutive stir predominance the Pentax K100D Super is the addendum of a ruckus removal pursuit in that pragmatic network the Pentax K10D. As with that camera, the K100D Super uses its Shake Reduction mechanism as part of a two-pronged approach to fighting dust on the image sensor, shaking the sensor assembly at high frequency to free any dust that has stuck to the low-pass filter over the image sensor. An adhesive sheet captures the dust and prevents it returning to the sensor. The other portion of the dust removal function is a vapor-deposited fluorine compound applied to the surface of the low-pass filter, making dust less likely to adhere in the first place.

Other quality of the Pentax K100D Super not unlike since the camera body, supposition sensor, viewfinder, LCD display, storage, connectivity options besides etc. are uncut essentially lone to the material Pentax K100D model. The supplement of SDM lens help and dust removal has added a scant 0.3 - 0.4 of an ounce to the weight of the newer K100D Super variant.
