There are sellers repeatedly offering AFD lenses as though they will work with the 6000 series cameras, specifically the 6008AF. There is one current listing bundling a 6008AF camera with a Xenotar 80/2,8AFD. Don't get burned! Only the HY6 series of cameras can set the aperture on an AFD lens. AFD lenses have no aperture setting ring, the aperture value can only be set electronically from the handgrip of the HY6 cameras. The HY6 cameras offer backwards compatibility for lenses back to SLX, but the AFD lenses are not compatible with prior cameras if you want to control the aperture.
