When it comes to focusing in street photography, zone focusing is arguably the best way to ensure that you get your subject sharply in focus the first time and every time. The reason for this is because generally autofocusing algorithms won’t be able to keep up with you making a split second decision, lifting the camera to your eye, analyzing the scene to figure out what to focus on and then releasing the shutter. In the entire moment that it took you to read that sentence the moment is simply gone.
YouTube user Tim Heubeck recently did a video on how to zone focus a street scene by using his Fujifilm X Pro 1 and the 23mm f1.4. It more or less requires that you use the distance scale, depth of field scale, and aperture scale altogether in order to nail the photos sharply in focus. This is much better demonstrated in a video–which is after the jump.
