The Adapter for M42/Universal Lenses to Pentax Q Cameras from Dot Line allows you to use M42/Universal Screw Mount lenses on Pentax Q mirrorless cameras. One of the most appealing aspects of small mirrorless cameras like the Pentax Q is the availability of a wide range of interchangeable lenses, including non-Pentax lenses. This adapter makes it possible to mount a M42/Universal lens to your Pentax Q camera, however it does not transfer all the functions from the camera to the lens, such as auto focus, but automatic exposure metering (stop-down metering/aperture priority) is possible. The lens will focus to infinity using this adapter.
