Rolleiflex AFD Lenses
Rolleiflex AFD (auto focus digital) Lenses are made to work with the Hy6, AFi, and Hy6 Mod 2 cameras which have fully automatic control. The lens value will be recognized by Hy6 and Mod2 cameras when using some digital backs and the focal length will be recorded into the EXIF.   As the AFD lenses do not have an aperture ring, they are not suited for use with the 6008AF cameras except in fully auto modes. If you still have a 6000 series body, consider buying the AF versions instead.
