Pentax has announced two upgrades to its premium DSLR, the K-5, in the form of the Pentax K-5 II and Pentax K-5 IIs.


On the face of it, the upgrade is fairly minor, with the cameras both featuring an APS-C format CMOS sensor with the same 16.3MP resolution, Prime II processing engine, 7 FPS maximum continuous shooting rate, 77-segment metering, sensor-shifting Shake Reduction system and 100 percent 0.92x magnification viewfinder as the Pentax K-5.
However, the AF system has been updated to a SAFOX X AF module, which has a sensitivity range of -3 EV to +18 EV. Pentax claims that this gives the new cameras better AF performance in low light, and improved subject tracking with moving subjects.


In a similar move to Nikon with the D800 and D800E, the big (only) difference between the Pentax K-5 II and Pentax K-5 IIs is that the K-5 IIs doesn’t have an anti-aliasing filter over the sensor. (more…)
