Pentax q introduced.

20 1 1 On June 23rd, the Pentax Q, the world's lightest interchangeable lens digital camera, was released. Pentax Q adopts newly developed Q bayonet, and its diameter is shortened to 2/3 of the length of traditional K bayonet. The flange distance (the distance between the lens mount plane and the surface of the photosensitive element) is effectively shortened, which is only 1/5 of that of the traditional K-mount camera, and the mount is directly reduced by 2/3. At the same time, the size of the imaging ring of the lens is optimized to better match the size of the photosensitive element. The Pentax Q-mount system also eliminates the optical viewfinder, mirror box, focusing screen and AF sensor, and the camera front panel is equipped with a unique quick dial wheel to provide users with nine unique Smart Effect visual effects in a quick way. The camera body is made of aluminum-magnesium alloy, with high-quality and high-grade texture materials and surfaces to increase its durability. Pentax Q uses 1240 effective pixels 1/2.3 inch back-illuminated CMOS image sensor and a new generation imaging engine, combined with a high-performance Q-mount lens, to provide high-definition images. The back of the fuselage is equipped with a 3.0-inch color LCD screen with 460,000 pixels. The resolution of Pentax Q is 1920 x 1080 (30 frames per second), and it adopts H.264 encoding format for full HD video shooting. It has micro-HDMI port, HDR (high dynamic range) high dynamic range shooting mode, SR (Shake Reduction) anti-shake mechanism and DRII(Dust Removal II) dust-proof system.
