Beginning Nov. 18, Sony will offer a free firmware update for the A7 Mark II that gives the year-old camera a decided facelift. The update adds uncompressed 14-bit RAW image capture — a great feature for those who shoot RAW. More importantly, the download activates phase detection autofocusing so the mirrorless camera can use a wider selection of lenses — including select Canon glass with an optional adapter. (See our A7R II review for more details). Another great enhancement is that you can choose between phase detection AF or contrast detect, right from the menu.

The A7 II is the latest Sony full-frame camera, along with A7S II, A7R II, and RX1R II to offer uncompressed RAW capture, which becomes a selectable feature (uncompressed/compressed RAW) within the menu system. A much-requested feature from users, it delivers even better image quality.

It is now the second Sony camera, along with the A7R II, to offer fully functional phase detection AF with E-mount lenses. The firmware update also activates the 117-point focal plane phase detection AF sensor for non-Sony FE lenses, such as select Canon glass with an optional third-party adapter, as well as Sony’s extensive collection of A-mount lenses, via Sony’s LA-EA3 mount adapter.

In addition to these upgrades, the Movie button can now be assigned to a custom button, making this function more easily accessible. Users have complained about this for years, so it’s good to see the company is listening.

The new firmware, version 2.0, will be available for download through Sony’s e-support site, on the product page for model ILCE-7M2.
