This adapter allows you to shoot all of your Pentax K-mount lenses on cameras such as the Panasonic GH2 and AG-AF100. It will work with all micro 4/3 mount cameras, allowing a whole new line of lenses to be used. It provides aperture control on all Pentax DA-series lenses without a manual aperture ring. However, it will not transfer EXIF data or autofocus. It will work Pentax FA-series lenses with manual aperture rings as well, but the aperture ring must be closed down and locked.
This adapter provides no electronic communication between the camera and lens. All aperture and focus adjustments must be made manually on the lens itself. The aperture selected will not be displayed on the camera, and it will not show up in the EXIF data.
