Pentax Q series

The Pentax Q series is a series of mirrorless interchangeable-lens cameras made by Pentax and introduced in 2011 with the initial model Pentax Q.[1] As of September 2012, it was the world’s smallest, lightest interchangeable lens digital camera.[2] The first models used a 1/2.3" (6.17 x 4.55 mm) back-illuminated sensor CMOS image sensor. The Q7, introduced in June 2013, uses a larger 1/1.7" type sensor (7.44 x 5.58 mm).[3]

Characteristics

The Q series small sensor size means that it has a crop factor of 5.6× (or 4.7× for the Q7 and Q-S1) and a short flange focal distance (FFD) of 9.2mm. With the 5.6× crop factor, an adapted 100mm lens has the equivalent field of view (FOV) of a 560mm telephoto in the 35mm full-frame format. An additional implication of the 5.6× crop factor is that depth of field (DOF) is increased proportionally for any given aperture setting. This gives the Pentax Q an advantage over larger formats in some situations that can offset the other limitations that arise from its smaller sensor size.

The short FFD of the Pentax Q series enables lenses from many manufacturers to be adapted to it, including: Olympus OM, Canon FD, Minolta, M42 screw mount, M39 Leica, C-Mount, D-Mount, Pentax K, and Pentax 6×7.[4] A Pentax adapter with a synchronized shutter for Pentax K-mount lenses was released in October 2012.[5]

The camera is equipped with 'SR' sensor-shift image stabilization technology to improve image quality when using the camera without a tripod. It works with all native and adapted lenses. The Pentax Q also features a "blur" mode to provide a pseudo shallow focus effect when desired.
