Sony a7rII user here but this concerns all models.
Firmware update for EFCS to auto-disable past 1/2000 sec with any Sony camera (this would disable banding on most models)
Firmware update to make APS-C mode still and video independent e.g. have it enabled for video but disabled for still photographs
Firmware update to Split the focus screen so you can magnify focus & compose the shot at same time (useful for manual focus lenses) for all models e.g. have a small square in the centre of the frame 100% magnify
Firmware update to add "my menu" to all Sony cameras
Please upvote this. Sony gets criticised for not listening but not many people support each other.
