It’s time to clear out the myths and mysteries regarding AF speed. If you want a higher keeper rate with any lens, you’ll love this one!

In this video, we’ll answer these questions:

A great post as always! This and your Nikon Autofocus book has most all of my questions answered except for one I could not find in either. Perhaps this would be of interest to other BIF photographers well. Assuming a BIF is coming directly or even at an angle at you, what effect if any does the frames per second have on the focus being able to keep up? Specifically dealing with the D500 at 10 frames per second. Is the system fast enough to record the setting for the lens elements between each and every exposure/mirror cycle? Or will… Read more »

Great tutorial as always. Your videos are so professionally done. Do you do all the graphics and what gear are you using? Thanks, April. Hope you are well.

Hello Steve,
What a great video! Tremendously helpful as always.
One takeaway. At the 9:11 mark in the video there is a viewfinder capture that shows the bar indicating focus distance. Right above the bar the focus distance of 40 meters is indicated numerically. If this numerical focus distance is accurate, it would be tremendously helpful for landscape work. My Z8, as currently set up, displays the bar, but not the numerical distance. For the life of me, I can’t figure out how to turn this numerical display on. Any guidance would be appreciated!
