Built around a 1/2.3″ sensor, the Q, with a magnesium alloy body with rubber front coating, is a fraction of the size of even the smallest existing mirrorless cameras and is the first really pocketable model.
It comes with a 47mm equivalent F1.9 prime lens but other lenses are available including the Pentax 02 Standard Zoom lens which offers the flexibility of a 3X zoom in a very compact form factor. (Focal length equivalent to 27.5-83.0mm in the 35mm format, maximum variable aperture of F2.8-4.5.)
