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.[3] 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.[4] This increased AF base length helps to improve focus accuracy, in particular with fast (wide aperture) lenses and in low light.[5]

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).

Externally, the cameras are distinguished by a recessed screen, where the K-5 had a flush-mounted one.[6] The K-5II/IIs has a gapless design—the typical air gap is avoided by the use of a special resin—helps to reduce internal reflections and gives better visibility in bright light.[7] The material of the screen has been changed from plastic to tempered glass, which is scratch resistant.[8][9] Like its predecessor, the K-5 II/IIs is fully weather-sealed.[7]

It has the highest camera sensor rating of any Pentax APS-C camera, according to DxO Labs, with a score of 82.[10]

Bundling

The K-5 II/IIs are available in two different kits, one including the DA 18–55 mm WR lens, and the other the DA 18–135 mm WR lens, as well as a body only.[7]

gollark: They use some random Allwinner one.
gollark: What do you mean "open source"? Open source software is able to run it fully? Someone's released all the hardware design files?
gollark: Error correcting codes at least.
gollark: I doubt it. There's presumably some intermediate encoding step going on.
