Introduced as "The world's smallest interchangeable lens system camera…" The Pentax Q system is composed of 4 bodies (Q, Q10, Q-7, Q-S1) and eight lenses: Three zooms (mid-range, wide and telephoto), one high quality prime (8mm f1.9), and 4 "specialty" lenses (fish-eye, "toy" wide and tele, as well as a single element "lens-cap"). The zooms and HQ prime have leaf shutters (with built-in neutral density filters) which sync with flash up to 1/2000 of a second. The other lenses (and all adapted lenses) use the camera's electronic shutter.
The camera's small sensor size (1/2.3") means that the Q has a crop factor of 5.6× and a short flange focal distance (FFD). With the 5.6× crop factor, a 100 mm macro lens (for example) becomes a (35 mm equivalent field of view) 560 mm extreme telephoto or an extreme close-up lens. An additional implication of the 5.6x crop factor and associated optics is that depth of field (DOF) is increased proportionally for a given aperture setting (in comparison to the 35mm equivalent depth of field at the corresponding aperture). Later models of the Q (Q7 and Q-S1) have a larger sensor size (1/1.7") which has a crop factor of 4.6×. In some applications the Pentax Q has an advantage over more conventional mirrorless sensor formats, which offsets other limitations arising from the smaller sensor size. Moreover, the Pentax Q has a wide range of digital effects and controls including High Dynamic Range (HDR), multiple scene modes, and a bokeh function which, when activated, can enable a shallow focus effect.
The short FFD of the Pentax Q allows the use of third-party adapters to mount lenses from many manufacturers on the Pentax Q body, including Olympus OM, Canon FD, Minolta, M42 screw mount, C-Mount, D-Mount, Pentax K, Pentax Auto 110, and Pentax 6×7.
The camera is equipped with sensor-shift image stabilization technology to improve image quality at slow shutter speeds or when using telephoto lenses. It has a "focus peaking" function as well. Sensor shift and focus peaking functions also work with adapted lenses.
