Pentax Q Black With 8.5mm F/1.9 AL [IF] Silver (40.5) & 5-15mm F/2.8-4.5 Silver (40.5) Digital Camera {12.4 M/P}

The Pentax Q features the newly developed Q mount, with a mount diameter shortened to approximately two-thirds of that of the conventional K mount. This was made possible by reducing the flange back (the distance from the lens mount surface to the image sensor surface) to nearly one-fifth of that of the K mount, as well as by optimizing the size of image circle of its lenses to be proportioned to the size of the compact image sensor. The Q mount system also eliminates an optical finder, mirror box, focusing plate and AF sensor, making the Pentax Q's body the smallest and lightest in its class. The body has been made of magnesium-alloy, which gives an elegant, high-quality texture to the compact, lightweight camera body while improving its durability.
