The Pentax K-5 II is the nearly identical twin of the K-5 IIs reviewed two weeks ago. This one is built around the same 16 MP CMOS sensor but uses an anti-alias filter to avoid moire artifacts. The remaining specifications are just as impressive: ISO 80-51,200, 7 FPS, Full 1080p HD video and the most sensitive aufocus system of any currently available camera, matching the K-5 IIs of course. This high-end DSLR is fully weather-sealed and freezeproof to -10C (14F), has a 100% coverage optical viewfinder and dual-controls dials. Read the review and be sure check out the ISO comparison with its more expensive sibling.
