The NOVOFLEX A-Mount to Minolta AF Body Adapter from NOVOFLEX allows a NOVOFLEX Medium Format Lens Adapter, a NOVOFLEX Universal Bellows or a historic NOVOFLEX Follow Focus Lens (Series B, C or D) to be mounted to a Sony A-Mount/Minolta AF camera. Although the lens will fit physically, automatic diaphragm (AE metering), or any other functions are not retained using this adapter. In this case you will need to meter in "stop-down mode" since the lens does not have the ability to have its aperture controlled by the camera body.
