Pentax K-r
The Pentax K-r is a 12.4-megapixel digital single-lens reflex camera, announced on September 9, 2010, and replaced the K-x in Pentax' line-up, with which it shares many features. The K-r is available in three body colors in North America, with other colors available only in the Japanese market. The K-r introduces a new SAFOX IX autofocus system and has a 3-inch display.
The image quality of Pentax K-r and K-x is identical, but colour fidelity in JPEG output has been increased. The K-r has been improved over the K-x in other areas, such as the K-r showing the active focus point in the viewfinder when the shutter button is half-pressed, the K-r offering the joint second-widest ISO range in the Pentax line-up along with K-30—100-25600 in extended mode, which only the K-5 exceeds, having the joint second-fastest continuous shooting of current Pentax DSLRs, and using rechargeable battery Li-Ion D-LI109 as standard, but having the ability to use 4 × AA batteries with optional battery holder. The K-r also has a slightly larger, and much higher resolving display at 921,000 pixels vs. the K-x's 230,000.
