Phase-Detection AF support for A-mount lenses.

    IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.

    The ILCE-7M2 offers Phase-Detection AF that provides better AF response compared to conventional Contrast AF, even when using an A-mount lens connected via adapter LA-EA3 or LA-EA1 that is not equipped with a dedicated phase-detection AF system. As a result, wider AF coverage area, higher number and higher density of AF points can be used.

    Phase-detection AF 2


    • Fast Hybrid AF is not supported when using Contrast AF.
    • Full-frame shooting is not possible with the LA-EA1 or LA-EA2 (shooting becomes equivalent to using APS-C size image sensor).
    • Make sure to update the camera firmware to the latest version. Downloads are posted on your model support page.
