Pentax K-r
The Pentax K-r is a 12.4-megapixel digital single-lens reflex camera, announced on September 9, 2010,〔http://www.pentaximaging.com/slr/K-r_Black/〕 and replaced the K-x in Pentax' line-up, with which it shares many features. The K-r is available in three body colors (black, white and red) 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. There is a known issue with front focus and the Pentax K-r. In low kelvin light the camera has severe front focus and this cannot be corrected with the AF fine tune. Pentax did not solve the problem, it is thought the AF module is responsible for the problem.
The image quality of Pentax K-r and K-x is identical,〔(【引用サイトリンク】title=Pentax K-r Review )〕〔http://www.dxomark.com/index.php/Cameras/Compare-Camera-Sensors/Compare-cameras-side-by-side/%28appareil1%29/672|0/%28brand%29/Pentax/%28appareil2%29/639|0/%28brand2%29/Pentax〕 but colour fidelity in JPEG output has been increased.〔http://www.imaging-resource.com/PRODS/KR/KRIMAGING.HTM〕 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 (K-x: 12800 in extended mode), having the joint second fastest continuous shooting (6.0 fps) of current Pentax DSLRs (same as the K-30), and using rechargeable battery Li-Ion D-LI109 as standard, but having the ability to use 4xAA batteries with optional battery holder (the K-x uses AA batteries exclusively).〔 The K-r also has a slightly larger, and much higher resolving display at 921,000 pixels vs. the K-x' 230,000.
== HDR (high dynamic range) capture ==
As in the K-x, the user can choose to have the camera take three images at different exposures and have them combined into a high dynamic range JPEG image. In contrast to its predecessor, the Pentax K-r offers the option to auto-align the images.〔http://www.steves-digicams.com/camera-reviews/pentax/k-r-slr/steves-conclusion-123.html〕
