There has been a lot of hype around Sony's a9 III announcement and the presence of a global shutter image sensor. Everything about the camera body seems to be marketed around speed, which fits the technology built into the camera. Almost immediate, there was some chatter if Canon would go the same route in their next line of EOS R cameras.
December last year, Canon showed off a couple of full-frame global shutter sensors, however they don't appear to be intended for consumer photography gear. Both the LI5030SAI and LI5030SAN sensors are 19mp, with a 12-bit readout at 57.99fps. Though, both are intended for industrial applications.
Canon did have a global shutter in the discontinued Canon EOS C700 GS cinema camera. We do expect to see more global shutter equipped cinema cameras in 2024.
We have been told by an extremely reliable source, that Canon will not be bringing a global shutter to either the EOS R5 Mark II or EOS R1. It was suggested that readout speeds will be good enough to make the advantages of a global shutter less prominent, while maintaining the expected image quality in the next generation prosumer and flagship camera bodies. The same source claims that Canon's next image sensors will have bigger advancements in performance than we're used to from a new generation of Canon consumer sensors.
We'll have to wait and see if Sony has solved some of the challenges with global shutters once the camera's final version gets into the hands of photographers and videographers. We imagine that they have.
