The Sony LA-EA4 Adaptor allows A-mount lenses to be used on E-mount bodies, providing phase detection autofocus capability. This lens adapter is designed for Sony cameras for use with certain E-mount bodies and allows mounting Sony, Minolta and other A-Mount lenses (with varying degrees of compatibility). There is also a MOD called "Monster Adapter" that enhances the compatibility of the LA-EA4 adapter and utilizes on sensor autofocus. Monster adapter is available separately.
