Sony firmware update 3.10 for a7 cameras, a6000, a5100 now available
Sony has released firmware update 3.10 for the a7R II, a7R, a7S, a7 II, a7, a6000 and a5100 camera models. The update primarily brings new lens support and is available to download now from Sony’s support website.
All updates bring the ability to use AF with the Sony FE 85mm F1.4 GM while recording movies. The changelogs for the a6000, a7, a7 II, a5100, and a7R II all mention ‘Phase-detection AF is supported,’ which we’ve asked Sony for some clarification on.
Update from Sony: ‘The firmware update enables the on-sensor Phase Detection AF – for those cameras that include on-sensor Phase Detection AF – to operate properly with G Master lenses.’ This means the a7, a7 II, a7R II, a6000, a5100, but not the a7R, a7S, a7S II (which lack on-sensor phase-detect). The Sony a6300 is not included, as it already has the firmware update required for phase detect with G Master lenses.
Additionally, updates for all but the a7R II enable the correct lens data to be recorded in EXIF.
