Two months ago, Sony released a major firmware version for its popular a7 III and a7R III mirrorless cameras. Version 2.0 brought new features and improvements… including the ability for a wide range of adapted lenses to make use of all the camera’s autofocus modes.
The update “Adds support for Zone, Expand Flexible Spot, and Lock-on AF focus areas when using the LA-EA3 mount adaptor,” Sony writes.
Sony specifically mentioned the LA-EA3 mount adapter, which is designed to let photographers use Sony A-mount lenses on E-mount cameras. But it seems the new feature goes well beyond that use case and includes all lenses, according to DPReview.
