The venerable pentax  k10d  a real world Workhorse

The Pentax K10D Digital SLR features an array of Pentax innovations including 10.2 effective Megapixels and a Pentax-developed Shake Reduction (SR) system that effectively offers a 2.5 to 4 stop advantage for sharp, blur-free images even under difficult shooting conditions, such as macro and telephoto photography or low light settings without a flash. Also featured is a newly developed Pentax Real IMage Engine (PRIME) designed exclusively for Pentax digital SLR cameras to produce well-balanced, true-to-life images. Pentax also incorporated a new high performance 22-bit A/D converter to quickly transfer images with accurate color tones and richer gradation from the CCD to the imaging engine. The new Dust Removal (DR) system incorporating Pentax-original Special Protect (SP) coating helps keep the CCD surface dust-free, and adds a shift mechanism to shake dust off the CCD. All this is housed in a dependable dust-proof, weather-resistant body construction featuring 72 seals throughout the camera to allow photographers to continue shooting even in dusty or rainy environments.
