The K-x design is based on the PENTAX K-m, an entry-class digital SLR camera launched in October 2008 that early on gained popularity for its compact, lightweight body and simple, user-friendly operations. With the addition of a newly designed CMOS image sensor and an upgraded high-performance imaging engine, the K-x offers outstanding photographic performance at nearly the same level as upper-class models. This includes high-resolution, fine-detailed images delivered by approximately 12.4 effective megapixels, super-high-sensitivity photography and high-speed continuous shooting. The K-x also features an array of advanced functions, including Live View shooting and movie recording. It also provides a pair of handy functions designed to produce highly personalized images with great ease: an upgraded digital filter function to accommodate more sophisticated image processing, and a new cross process mode to produce unexpected, eye-catching finishing touches with unique, intriguing colors. The K-x is not only the perfect camera for first-time digital SLR camera users, but also serves as the ideal backup camera for more experienced photographers.
