Tirei agora de um grupo de discussão da Z6/Z7.
“I went to the Photography Show in the UK, and Nikon has a couple of Z7 with the May firmware with eye-af. I was lucky enough to play with one!
Impression on the show floor is that it's very accurate. Using the 50mm 1.8s and 85mm 1.8G it has always nailed the eyes. This is even when the person are wearing glasses. The eye af is fast, responsive and the function to switch eyes are great. It only operates in Auto-AF mode on the camera we have. Unfortunately we were not able to test on 1.4 glass. What we have seen looks great!
We were not able to save results on cards, but was able to zoom in to see the results at 100% at the back of the screen.”
