Nikon Z7
Nikon NIKKOR Z 35mm f/1.8 S

Aperture Series: Twisted Aspen Trunks, Evaluating Focus Accuracy in Dim Light

Under most conditions the Nikon Z7 does a superb job of accurate focus in which the depth of field is centered around the focus point (though not always).

This series evaluates the ability of the Nikon Z7 to center the zone of focus at f/1.8, f/2.8, f/4 and beyond, a challenge harder than it sounds in dim light, what with the pronounced focus shift of the Nikon NIKKOR Z 35mm f/1.8 S.

* See the comments on compensating for focus shift in Sage, Aspen, and Waterfall.
