It’s not easy shooting moving action with a small point and shoot camera, or any camera that doesn’t have a sophisticated autofocusing system. I’m too lazy to carry around my DSLR because of the burden of weight and space, so what can I do? Easy, I just zone or scale focus. It’s scary at first, but once you get the hang of it, it’s actually faster than autofocusing. Some of the greatest photographers who used old school Leica rangefinder cameras to shoot action depended on zone-scale focusing. This is how its done…

The first thing you do is figure out the distance you want to shoot from your subject. I find 2.5-5 meters is the best range with a fixed focal length wideangle lens, 28-35mm equiv angle of view. The wider the angle of view, the more background depth of field you will have. This is why its easier to zone focus with a wideangle lens versus a telephoto lens.

Choosing your aperture is easy enough, and if you stop down enough, you will see that often you have a 2-3 meter range that is in focus around the actual focus distance you choose. The problem is, your shutter speed starts to get slower, as you’re letting less light hit the sensor. I would recommend not shooting slower than 1/500th of a second, but over 1/1000th is ideal. Because of this, you have to choose a higher ISO to compensate for this, usually 1600-3200 for an APS-C sized sensor camera, and much less on a smaller sensored camera. Most of my Ricoh GR-D IV action images were shot at ISO 200 or less during the day, while the Leica X-VARIO was shot at ISO 1600, even though both were set at similar focal lengths, focal distance and equivalent depth of field. Another advantage to smaller sensored cameras!
