Sony LA-EA2 Mount Adapter
Description (from B&H): The black A-Mount to E-Mount Lens Adapter from Sony enables you to attach virtually any A-mount lens to an Alpha E-mount full-frame digital camera body. Teleconverters and Minolta XI lenses are not compatible. The adapter features a built-in AF motor, aperture-drive mechanism and Translucent Mirror Technology to enable full-time, continuous, TTL phase-detection autofocus. AF is supported with all A-mount lenses except STF models, and auto exposure will be enabled with all compatible lenses.
Translucent Mirror Technology effectively directs light to both the imaging and focus sensors simultaneously, enabling AF to work seamlessly even during video recording and continuous shooting. For video, aperture is fixed at the maximum f/stop of the lens or at f/3.5, whichever is lower.
