Sony A1 and A7sIII firmware update will bring many more features than you expect!
Two sources now told me that we can expect a lot more features to be implemented than previously disclosed by Sony. This should bring both the Sony A1 and Sony A7sIII on par or ahead of the competition.
The bad news of this rumor is that it might means that the A1II (and A7sIV) might not going to be released any time soon.
