Today we released updated firmware for our αNEX E-mount cameras, more specifically firmware update 2.0v for Lens/Adapter. The firmware update applies to E-mount models launched prior to Oct 2011, so models getting the firmware update include the αNEX-3, NEX-5, NEX-C3 cameras, as well NEX-VG10 Handycam Camcorder and even a model in our professional camera line, the Sony NEX-FS100U.
In these cases, the new firmware provides compatibility with the recently launched LA-EA2 translucent mirror Lens Mount Adapter. Prior to this firmware update, the LA-EA2 only worked with the αNEX-5N , NEX-7 and NEX-VG20. We know owners of the previous models were eagerly asking for compatibility to enjoy phase detect autofocus when using one of Sony’s A-mount lenses.
The LA-EA2 is unique in that it replaces the Contrast AF of the E-mount camera with the Phase Detect AF of Sony’s Translucent Mirror DSLRs. The original LA-EA1 mount adaptor allows only contrast detect AF, with SSM and SAM series A-mount lenses, and no autofocus with others. Even with the AF capable lenses, autofocus wasn’t nearly as fast as with A-mount DSLRs because DSLR lenses aren’t really optimized for the Contrast AF found in all mirror-less cameras. With the LA-EA2, a microcomputer driven Phase Detect AF system is built directly into the adapter, which allows the camera to focus just as fast as a DSLR – and with all A-mount AF lenses! This firmware update lets the earlier cameras recognize the LA-EA2 adaptor when it’s attached, and prioritizes the adaptor’s AF system over the camera’s. The result? Super-fast Phase Detect AF functionality for all A-mount autofocus lenses when using LA-EA2 with earlier E-mount cameras.
So for owners, I’m guessing you’ve got your camera in hand ready to snag this firmware. Below are some quick links to get you there. Enjoy!
