Pentax Adapter Q For K-Mount Lens (Built In Shutter) (5.5X) Description


Pentax Lens Adapter for Camera - K-mount

Extra-powerful super-telephoto shooting. By using this new mount adapter to attach a K-mount lens to PENTAX Q series cameras, the focal length of the lens is extended by approximately 5.5 times in the 35mm format. This means, for instance, that the smc PENTAX-DA300mm F4 ED[IF] SDM telephoto lens can be used as a 1650mm super-telephoto lens (in the 35mm format) for effortless photography of celestial bodies and distant scenery using a very compact, light digital imaging system. A full range of K-mount lenses. Thanks to this mount adapter, a total of 215 lensescan be used on the PENTAX Q series, ranging from fish-eye lenses and uni-focal wide-angle lenses to telephoto zoom lenses. So the photographer can take advantage of a wide variety of perspectives and visual effects with quick, effortless lens changes. It is even possible to capture a microscopic world otherwise difficult to observe closely with the naked eye.
As of June 15, 2012
Only manual focusing is available with K-mount lenses. Built-in mechanical shutter. A mechanical shutter has been incorporated in this adapter to prevent "rolling shutter distortion" - a problem that results in distorted images of the subject, due to the camera shake caused by photographing fast-moving subjects and/or by using a super-telephoto lens. Other features. - Manual aperture control possible - Tripod bracket (optional) available to stabilize the camera system - Camera shake is automatically compensated for with any lens, simply by inputting the focal length of the mounted lens to the PENTAX Q series camera.
