Sony has just released firmware v1.20 for the Sony a7R IV.
This firmware addresses autofocus performance when recording movies with the Sony FE 12-24mm F2.8 GM lens (* B&H Photo) and improves the overall stability of the camera.
There is no mention of improving autofocus performance with the a7R IV + 200-600 which some shooters are having issues with, although there are many including myself that have no issues.
If you do have autofocus issues with the a7R IV + 200-600 and after installing this firmware notice an improvement, please do drop a comment below. Thanks!
Firmware v1.20 Benefits and Improvements
- The Auto Focus (AF) performance is improved when recording movies with the FE 12-24mm F2.8 GM (SEL1224GM) lens
- Improves the overall stability of the camera
Firmware v1.20 Known Issues
Please note that one member in our Sony a7R IV Shooters Facebook Group has reported that their Commlite apdater no longer works after installing the v1.20 firmware and they can no longer auto focus with any of their Nikon lenses. They tried with the 70-200 2.8 200-500 5.6 and nifty fifty. So if you use this adapter I would recommend not upgrading until Commlite updates their firmware to address this, Sony will not do anything for third-party adapters I’m afraid.
