Aut­o­fo­cus points

Andy says… “Ev­ery cam­era has a fo­cus point in the cen­tre of the frame. It also has any num­ber of ex­tra points built around this. Most cam­eras are weighted to us­ing the cen­tre point be­cause the sub­ject is usu­ally in the cen­tre. This is, of course, true, but you should also add ex­tra ex­pand­ing points so that when your sub­ject moves off-cen­tre the fo­cal point moves with it. This cus­tomi­sa­tion is down to the in­di­vid­ual cam­era and pho­tog­ra­pher.

“It’s not al­ways how you have the AF set up that mat­ters most. It’s also about how you fol­low the sub­ject with the AF points. Al­ways fol­low the ac­tion, an­tic­i­pat­ing when you are go­ing to re­lease the shut­ter.

“Se­condly, set your D-SLR up so that the aut­o­fo­cus sys­tem is ac­ti­vated by the back but­ton rather than the shut­ter but­ton. This will give you more con­trol as you can use your thumb to con­trol the AF and your in­dex fin­ger to con­trol the shut­ter re­lease.”
