Pentax Q

Jump to: navigation, search

Announced in 2011, the Pentax Q is an entirely new interchangeable-lens digital camera system. Its surprisingly tiny dimensions are made possible through using a sensor size more typically found in compact point & shoots, roughly 6×4.5 mm (cryptically known as 1/2.3" by industry convention).

The the Q has a somewhat retro-styled magnesium alloy body; the sensor is a back illuminated 12-megapixel type (likely from Sony). Along with this, Pentax offered a fast standard f/1.9 lens. (Because of the Q's small sensor size, its 8.5 mm focal length equals 47mm in 35mm equivalent terms.) Pentax also introduced a 27.5-83mm (35mm equivalent) f/2.8–4.5 zoom.

In addition, three lenses in the so-called Unique series were offered, as lower-cost "fun" options. A fisheye and a "toy camera" wide or tele lens were perhaps aimed at those attracted to a lo-fi/Lomography aesthetic, but not wishing to give up the convenience of digital. Adapters from other manufacturers are available for lenses with other mounts, most notably Pentax Auto 110 system lenses, which are seen as good alternatives to the Toy Camera lenses.

Other enthusiast-friendly features include the option of raw capture, 1080p video recording, and a flash hot shoe. Viewing is exclusively through a 3" diagonal, 460,000 dot LCD which practically fills the back panel of the camera.
