Phase-detection AF support for A-mount lenses.

Applicable Products and Categories of This Article

IMPORTANT: A firmware update (Ver.2.0) of the camera is required for using Phase Detection AF.

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 adaptor 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.



  • Fast Hybrid AF is not supported when using Contrast AF
  • Full-frame shooting is not possible with the LA-EA1/LA-EA2 (shooting becomes equivalent to using APS-C size image sensor).
