Add the creative possibilities of the large family of Pentax K-mount lenses
This handy and compact lens adapter makes it possible for you to use the large number of Pentax K-mount lenses made over the past four decades with your Pentax Q or Q10 compact interchangeable lens digital camera. Lenses used with this adapter will be subject to a 5.5x crop factor, effectively multiplying the focal length of the attached lens by 5.5 times. This means a 70-200mm zoom lens will become a super-telephoto zoom, with a focal length range of 385-1100mm (35mm equivalent). While that's a wonderful benefit, plan accordingly. You will not easily be able to shoot indoors using this adapter.
The adapter is compatible with your Q-mount camera's on-board Shake Reduction after some minor settings adjustments. It also features a built-in mechanical shutter to minimize the "rolling shutter" distortions that can plague electronic shutter systems. Manual aperture control is available on the adapter, and you will only be able to focus manually while using this item.
