The LA-EA5 35-millimeter full-frame adapter for A-mount lenses makes it easy to combine modern Sony E-mount cameras with A-mount lenses. This allows photographers to use the latest autofocus and high-speed shooting functions of current models with an E-mount bayonet mount even when using A-mount SSM (Super Sonic Wave Motor) or SAM (Smooth Autofocus Motor) lenses or A-mount lenses without an integrated focus motor. With the latest firmware, focal plane phase detection AF is supported when using SSM/SAM lenses on the following cameras: Alpha 7 III, Alpha 7R III, Alpha 7R IV, Alpha 6100, Alpha 6400, Alpha 6600, Alpha 9, Alpha 9 II, and Alpha 7S III. When using lenses without a built-in focus motor, focal plane phase detection AF is supported on the Alpha 7R IV and Alpha 6600. STF lenses can only be focused manually. Teleconverters are not supported. Compatibility information at: https://support.d-imaging.sony.co.jp/www/cscs/accessories/? area=gb&lang=en&mdl=LA-EA5
