The Pentax K100D and similar PentaxK110D are 6 megapixeldigital single-lens reflex cameras, launched in the U.S. on May 22, 2006. The K100D has a maximum resolution of 3008 x 2008, and can also down-sample to 2400 x 1600 and 1536 x 1024. The slowest metered shutter speed is 30 seconds and the fastest shutter is 1/4000 seconds.
On June 27, 2007, Pentax announced the K100D Super. It retains the features and the 6.1 megapixel image sensor of the K100D, while adding support for Supersonic Drive Motor(SDM) lenses and dust reduction technology. Although K100D Super was announced in June, it seems that camera was in production since January 2007 (manufacture date found in Exif data of shots).
The K100D, K100D Super and K110D have been discontinued in favor of the K200D and K-m.
