Do’s and Don’ts Aut­o­fo­cus

Aut­o­fo­cus can be swift and ac­cu­rate – but it can also do with a help­ing hand

DO Try to pre­fo­cus

Pre-fo­cus­ing the lens at a dis­tance near the sub­ject of your photo can slash the amount of time it takes the cam­era to aut­o­fo­cus.

DON’T Miss the point

You’ll need to keep the ac­tive AF points over a mov­ing sub­ject in or­der to keep them in fo­cus. Get some prac­tice in!

DO Limit the dis­tance

Some lenses have a fo­cus dis­tance switch that al­lows you to limit the fo­cus­ing range, and this can speed up fo­cus ac­qui­si­tion.

DON’T For­get the drive mode

If you’re pho­tograph­ing ac­tion, set the drive mode as well as aut­o­fo­cus to con­tin­u­ous, to en­able you to shoot se­quences of shots.
