Eye-detection autofocus, often referred to as Eye AF, is fast becoming a must-have feature. It works in a similar way to Face-detection-AF but of course, it homes in on a smaller target.
The big question everyone wants answering about Nikon Eye AF is does it work? Happily, the answer is yes, it does a pretty good job.
We wanted to see how a working photographer got on with it so we asked him to report back after using it.
Paul tested it in AF-C mode on his kids playing in the woods, as well as on posed-portraits in AF-S mode.
With a portrait subject quite large in the frame he found it locked on to the eye quickly and tracked accurately. Even when the subject turned a little side on, or was squinting in bright light, the focus box followed the eye well. However, the subject has to be quite close for it to find the eye.
When the subject is at around three-quarter length or further back, the Nikon Z7 usually finds the face, not the eye.
In the woods with the kids turning and dropping out of frame, it struggled a little more. Occasionally it locked onto something in the background and it was a little slow to reacquire focus when the subject can back into frame.
When it isn’t behaving you can quickly switch to normal tracking mode though. Paul found this pretty useful as it means you have a bit more control over what the camera is focusing on without having to come out of auto-area AF.
You can also switch between which eye the camera focuses on. When multiple eyes are detected, a yellow arrow appears at the side of the autofocus box. You can toggle between eyes using the camera’s joystick or D-Pad. With a single portrait this lets you select the left or right eye. With a group shots you can choose the best eye or person to focus on.
From what we’ve seen, we think that Eye-detection AF is a great additional feature for the Nikon Z series, and the Z6 and Z7 are among the best cameras with AF that you can currently buy.
You can get the Nikon Z7 from Wex Photo Video and Park Cameras in the UK, and from Adorama and B&H Photo Video in the US.
