Pentax K-5 II
The Pentax K-5 II is a 16.3-megapixel digital single-lens reflex camera, successor to the Pentax K-5, sharing its body shape with its two predecessors including the Pentax K-7, and making incremental improvements on the K-5. The Pentax K-5 II is available in two versions, the basic Pentax K-5 II as well as the Pentax K-5 IIs which omits the traditional low pass filter for greater sharpness but potentially greater moiré.
Both models have improved autofocus ability, particularly in low and tungsten light, down to −3EV, which at the time of release makes it the best low-light autofocus camera. Also improved is the sensitivity of the central AF area which now has an AF base of f/2.8 instead of the common f/5.6. This increased AF base length helps to improve focus accuracy, in particular with fast (wide aperture) lenses and in low light.
The Pentax K-5 II/IIs each have HD video capabilities, with resolutions of 1920×1080 (at 25 fps), 1280×720 (at 25 & 30 fps), 640×480 (at 25 & 30 fps).
