The K-5 IIs Digital SLR Camera from Pentax is a top-of-the-line APS-C DSLR camera. It offers a 16.3MP CMOS sensor with integrated analogue/Digital conversion circuitry for high resolution photos and video. And the K-5 IIs brings with it a new, highly advanced and extremely accurate 11 point SAFOX X autofocus system. This new autofocus system offers a wide EV focus range which means faster autofocus with less hunting in low-light situations and improved AF accuracy when using fast, wide-aperture lenses. The AF sensor also includes the Select-Area Expansion feature which automatically tracks moving subjects as they proceed across the frame.
