Sony A7 III / A7RIII firmware

Last month, Sony released firmware version 2.00 for the a7 III and the a7R III, and it brings a huge update for photographers using adapted lenses.

The new firmware allows all autofocus modes using adapted lenses. Sony specifies that this new functionality is specifically enabled with the LA-EA3 adapter, but I just tested it with my Metabones V and can confirm all AF modes were available. DPReview also tested it with both Sigma and Metabones adapters and saw the same results. This brings modes like Lock-on AF (for subject tracking) to adapted Canon lenses as well. With so many Sony shooters using adapted lenses, this is definitely huge news and another draw to Sony bodies. While you can expect a bit of a performance hit with some lenses, I’ve seen good results with many of my Canon lenses, good enough for all but the most demanding situations, and it’s made the decision to switch bodies far easier, as I didn’t have to immediately dump all my glass at a loss and buy an entirely new lineup. You can see the full list of changes and download the updates below.
