Nikon Z7 vs Sony a7R III Eye AF Comparison by DPReview

At  CP+ 2019, Nikon introduced its Z6 and Z7 cameras running firmware with Eye AF. Dpreview tested Nikon full frame mirrorless cameras compare Nikon Z7 side-by-side with the Sony a7R III.

Mirrorless enthusiasts are familiar with Eye AF which is found on Sony mirrorless cameras, including the a7 III and a7R III against which the Z6 and Z7 compete.

Nikon’s upcoming firmware is planned that will add Eye-detection AF, CFexpress support and Raw video over HDMI to the Z6 and Z7, with AF and AE improvements also coming in May. Check more details here.

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. This recognition (and how quickly it re-acquires the eye) is key to the performance of eye-detect AF, as we’re already pretty confident about the Z7’s ability to focus when requested.
