The Pentax Q's backlit, 12.4 megapixel, 1/2.3 inch (6.16 x 4.62 mm) CMOS image sensor
Pentax has announced the first pocket-friendly interchangeable lens camera to sport its new bayonet lens mount. The company says that its Q mount is about a third less in diameter than the more familiar K-mount, thanks to a reduction in the distance from the lens mount surface to the image sensor and by tweaking the size of the lens image circle to be proportionate to the sensor. The Pentax Q also makes use of a compact camera-sized sensor and sacrifices the onboard optical viewfinder, mirror box, focusing plate and autofocus sensor to help keep proportions to a minimum - making it about the same size as my Umbra credit card case. Other features of note include a programmable dial on the front for quick access to frequently-used settings, the ability to shoot full high definition video and a built-in flash that can pop up to help reduce red-eye.
