CP+ 2019: Nikon Z7 Eye AF side-by-side with Sony a7R III

Nikon's booth at CP+ includes Z6 and Z7 cameras running firmware with Eye AF. We tried it out, side-by-side with the Sony a7R III, to see how they compare. Both cameras do a good job of recognizing the subject's eye and sticking with it, even when she covers her face for a period of time. They're similarly fast to find the eye again, afterward. We weren't able to keep the images from the Nikon but will put it to the test as soon as we have the new firmware.
