Sorry folks for yet another Nikon Z 9 review but this camera is too cool…
How Good Is Nikon Z 6/Z 7 Eye AF and Can it Compare with Canon and Sony?
Jared Polin analyses the eye AF of the Nikon Z 6 (added via firmware update) in this 27 minutes video.
The Nikon Z 6’s Eye AF performance is compared with Canon and Soy full frame mirrorless systems (i.e. EOS R and Sony a7III)
The first video is the full review, the second one (4 min) shows only the side-by-side comparison with Canon and Sony.
