The PENTAX K10D digital SLR features several innovations including 10.2 effective megapixels and a 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) which produces well-balanced, true-to-life images.
