Sony’s reign as the king of full-frame mirrorless cameras is coming under fire. It has more experience than anyone else, so you’d hope it will come up with something special to take on the competition from Panasonic, Canon and Nikon.
The most likely camera to turn up next is the A7S III, the video-focused sibling of the Sony A7R III and A7 III. There’s quite a lot of chatter online about both this camera and the follow-ups to the current models, the A7 IV and A7R IV. These are expected in 2020-2021, though, and with Panasonic’s full-frame models on the way, Sony’s S-series model is the most pressing issue.
The current Sony A7S II can only shoot 4K video at up to 30fps, which Panasonic will beat in 2019. 60fps 4K is expected in the A7S III, and some even suggest 8K (30fps) capture is a possibility.
Sony has said “it will take some time” to prepare the A7S III, though. There’s every chance it may slip into 2020 along with the A7 IV, but we remain hopeful of seeing it in 2019.
