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. The Adapter for Contax/Yashica Lenses to Pentax Q Cameras from Novoflex makes it possible to mount a Contax/Yashica lens to your Pentax Q camera with a precision mechanical adapter. Such an adapter 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.
