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.
Sony a7R IV Forum & Facebook Group
If you are looking for further help and advice on the a7r IV or would simply like to share your photos, then please head over to our friendly Sony a7R IV Forum. If you prefer Facebook then I also run the Sony a7R IV Shooters Group.
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.

New to Sony, cannot find anywhere bulb mode on a7r4. If it is suppose to be like A 3 it does not turn orange and say bulb mode one click past 30 seconds. It does not go past 30seconds. It just keeps staying on 30 no matter how many times you click past it.I just got back from a 20 day trip everyone had threes and no 4s that I met along the way. No one knew on the 4.
Hi David. Are you using perhaps using the silent/electronic shutter? Bulb mode will only work with the mechanical shutter, you also need to be in M (manual exposure) mode.
Hi, On March the 8th Worls Womans Day I brought my Sony ILCE A7RM4. Since thenI have had two updates. Honestly it`s the best Camera one can buy & a luxury of 4 Sony G Prime Lenses 12-24 F2.8; 23-70 F2.8; 70-200 F2.8 & to top it 200-600 F5.5. I am on cloud 9. Thanks Sony’
