The Adapter Q for K-mount lenses allows the use of PENTAX K-mount lenses on the PENTAX Q Series cameras. 

Adding compatibility with a full range* of K-mount lenses opens up new photographic possibilities.

Extra-powerful super-telephoto shooting is obtainable with the 5.5X focal length multipler achieved with K-mount lenses
on the Q camera body. For example, the PENTAX DA* 300mm
F4 ED[IF] SDM telephoto lens can be used as a 1650mm super-telephoto lens (35mm equivalent).

Extra-powerful super-telephoto shooting

By using this new mount adapter to attach a K-mount lens onto the PENTAX Q series, 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-DA* 300mm 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 lenses* can be used on the PENTAX Q serise,** 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.

**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 serise.
