Focus shift shooting feature
Nikon Z7

Evaluated: Nikon Z7 Automated Focus Stacking aka Nikon “Focus Shift” Feature

For how-to on focus stacking see the focus stacking section in Making Sharp Images.

See also Configuring the Focus Stacking aka “Focus Shift” Feature on Nikon Z7.

This page shows two focus highly-complex focus stacking examples using the Nikon Z7 (ill-named) “focus shift” feature. The “focus shift” feature automates taking a series of images shifted in focus, starting at a closest point.

The Nikon D850 has performed brilliantly with this feature. What I wanted to know was whether the Nikon Z7 works equally well.

These images “pop” beautifully on a Retina display like the iMac 5K.
