Sony has announced the impending release of the LA-EA5, its newest A-mount to E-mount lens adapter. In addition to changing mounts, the new adapter provides autofocus support for Sony A-mount SSM (Super Sonic wave Motor) lenses, SAM (Smooth Autofocus Motor) lenses, and even non-motorized screw-drive lenses in still shooting modes.

Despite the ability to power non-motorized screw-drive lenses (limited to the a7R IV and a6600, at least for the time being), the LA-EA5 features a compact form factor, thanks to clever internal gear and motor positioning. Sony says the adapter provides ‘full support for focal plane phase-detection autofocus (stills only), wide-area focal phased detection autofocus (stills only), Real-time Eye AF for both humans and animals, Real-time Tracking and AF/AE (auto exposure) tracking for SSM/SAM lenses on nine most recently introduced E-mount cameras at up to 11 frames per second depending on the camera model. ’ The supported camera models, as of this press release, are as follows:
Sony a7 III
Sony a7R III
Sony a7R IV (up to 10 fps)
Sony a6100
Sony a6400
Sony a6600 (up to 11 fps)
Sony a9 (up to 10 fps)
Sony a9 II (up to 10 fps)
Sony a7S III
Sony says the LA-EA5 will be available in October 2020 for a suggested retail price of $250 / $330 CAD. You will be able to find a full compatibility list on Sony’s support page (currently shows ‘Coming Soon’ as of posting this article).
