Autofocus performance on modern cameras is impressive, but it's one of the areas where most photographers can't stand for anything less than the best they can get. So which of these three mirrorless bodies has the best subject tracking and autofocus for portraiture?
In our discipline, there are a few irritants that I can't abide; tripods that aren't sturdy, memory cards with slow write speeds, and sluggish recycle times on strobes are three that jump to mind straight away. However, poor autofocus performance easily tops the list, and whenever I encounter it, I am ready to shot put my camera into a canal.
I think most of us photographers have noticed it at some point. What's typically known as hunting is one of the most infuriating aspects of poor autofocus performance, where the camera cannot identify what the subject is and usually goes too close and then too far a few times before settling. If you're photographing products this is irritating, if you're photographing something that move, it could cost you a great shot.
In this video, Manny Ortiz compares the Nikon Z 6II, Canon EOS R5, and Sony a7 III for their autofocus performance when out on the street shooting portraiture. I'll let Ortiz present the information without coloring it any, but one takeaway for me is that the Nikon Z 6II is looking highly impressive on this front!
