Nikon Z7 Autofocus Accuracy: Pinpoint AF vs Magnified Live View Reference Frame

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

NOTE: there is no internet where I am shooting for the next few days. It is tedious and troublesome, but I am making an effort most days to descent for internet service once per day, but there may be exceptions. Please be patient when subscribing.

My review of the Nikon Z7 is in full swing, though I’m spending a lot more time evaluating/publishing than enjoying the gorgeous fall season and weather.

This page evaluates the consistency of Nikon Z7 Pinpoint AF autofocus at f/4 using the Nikon NIKKOR Z 24-70mm f/4 S, comparing it against a reference image focused at f/4 in 100% magnified Live View. All of the conventional autofocus frames were off, and with varying focusing precision.

Discussion includes what to do about the errors that are shown and best practices for this type of shooting.

Below, numerous freak rock slides wiped out big chunks of aspen in Lundy Canyon, sometime in the winter of 2017/2018. Thick layers of large rocks with mud made a slurry that wiped out and buried things; this slide is one of the larger ones, the next image is one of the smaller! Having visited Lundy Canyon for 20 years, I’ve never seen anything remotely similar in scope and sheer destructive power. What was excellent topsoil (for this altitude) is now jumbled rocks.
