Must Read: Nikon Z7 Aperture/Lens Diaphragm Behavior While Viewing/Focusing vs Focus Shift in Lenses

See my Nikon mirrorless wishlist and Sony mirrorless wishlist and and Canon mirrorless wishlist.

This page discusses how the Nikon Z7 behaves with respect to aperture behavior when viewing vs when focusing vs when shooting, including perspective on the Nikon D850 along with best practices for Nikon NIKKOR Z lenses vs model-citizen Zeiss Milvus and Zeiss Otus lenses.

Nikon Z7 Aperture/Lens Diaphragm Behavior While Viewing/Focusing

This is a must read for anyone shooting Nikon NIKKOR Z lenses. Includes a best practices discussion.

The Nikon NIKKOR Z lenses are a big disappointing to me because of poor performance at the wide end (24-70) and because of absurd amounts of focus shift (35/1.8). I don’t have high hopes for the Nikon NIKKOR Z 50mm f/1.8 which I have not yet tested.

I cannot reconcile that marketing hype with the 35/1.8 actual performance. In my view, focus shift and field curvature are the #1 and #2 lens performance bugaboos, but apparently Nikon thinks otherwise.

...every S-Line lens achieves new-dimensional optical performance including outstanding resolution that can keep pace with future imaging demands...

How bad is the focus shift of the Nikon NIKKOR Z 35mm f/1.8 S? And what to do about it?

Putting the behavior to comparative analysis (show-and-tell):
