Of all the features I’ve read about regarding the Sony A7RIII, this is the one that’s probably impressed me the most. I don’t often shoot tethered, but when I do, it’s often quickly. Usually, I’ve got animals in front of the camera, and they tend not to take direction very well. So, I’m shooting fast, then waiting for the computer to catch up.
According to this video from photographer Evan Guttman, that waiting all goes away with the new A7RIII. In burst mode, it manages to transfer shots from the camera to Capture One in under a second each over USB3. And yes, he’s shooting raw, not jpg.
