Sony LA-EA4 Mount Adapter
Sony LA-EA4 is an A-mount to E-mount lens adapter with built-in phase-detect autofocus and a translucent mirror. It lets many Sony A-mount and older Minolta AF lenses work on E-mount cameras while retaining autofocus, aperture control and automatic exposure, making it a practical bridge for owners of legacy glass. The adapter contains its own 15-point AF system, including 3 cross-type points, and uses a semi-transparent mirror to divert light to the dedicated AF module, so focusing is generally faster and more confident than simple passive adapters, especially with screw-drive lenses. In use it adds some bulk and a little light loss compared with a direct mount, but it is sturdily built and feels like a proper Sony accessory rather than a temporary converter. Real-world compatibility is strongest with many full-frame and APS-C E-mount bodies, though performance and feature support can vary by camera and lens combination. It is best suited to photographers who already own A-mount lenses and want to keep using them on E-mount bodies without giving up autofocus. On the used market, check the bayonet mounts for wear, make sure the aperture lever and contacts are clean, confirm the AF mechanism drives smoothly, and inspect the translucent mirror and internal surfaces for dust, haze or damage.
