Works with all digital SLR's using standard Sony A mount Lenses. 5-pin M-AF model - see below re AF. It will fit all 35mm Film and Digital SLR's using the standard Minolta / Sony A mount. If used with lenses with a slower aperture (e.g F5.6, F6.3 etc) then yes it will still physically fit and apply the focal length increase, but you will need to focus manually, there will be NO Auto Focus.
