Sony's new A6700 may have the best autofocus ever in a consumer camera.

The A6700 is a $1,399 camera that has the exact same autofocus system as Sony’s top-end $3,900 A7R V, an AI-enhanced version of Sony’s already legendary autofocus system, capable of identifying people and animals, and even planes, trains, and automobiles. Focus is clearly a really important part of photography, and one that we take for granted with our camera phones, but why is it such a big deal?

"This year we bought an A7R5, which I believe has the same AI autofocus system as the A6700, and it's absolutely incredible," aerial photographer Steven Holtzman told Lifewire via email. "One thing I've learned is that as long as you can see your subject in the frame, the autofocus system will lock focus every time. It's rare that I get a blurry photo because the AI autofocus system wasn't functioning as it should. You don't have to worry about missing the moment."

Just like our eyes, a camera has to shift the elements that make up the lens to get something in focus. If something far away is sharp, the foreground is blurred and vice versa. Our eyes do this automatically. The same goes for modern cameras, although you usually have to indicate what you want to focus on by moving a small square around the viewfinder with a d-pad.
