You can select either a single AF point or a cluster of AF points, or make all of the AF points active. The way in which you access AF Area mode varies between camera models, but the options available are largely the same. While the choice of AF mode dictates how the lens will be focused, the AF Area mode determines where the camera will focus. What's the difference between AF mode and AF Area mode?

This automatically detects whether the subject is stationary or moving, and switches the autofocus accordingly. Many cameras offer a third AF mode: AI Focus AF (Canon) or Auto AF (Nikon). By default, the camera will let you take a picture at any time, even if the subject isn't in focus. Once the autofocus system has achieved focus, it locks that setting in: you can take a picture, knowing that the subject will be sharply focused.Īs the name suggests, AI Servo/Continuous-Servo focuses the lens continuously, making it a good choice for tracking a moving subject. The One-Shot/Single-Servo option is the best choice for stationary subjects. These are One-Shot AF (Canon)/Single-Servo AF (Nikon), and AI Servo AF (Canon)/Continuous-Servo AF (Nikon). Let's assume you're sticking with autofocus for now, in which case double-check the switch on the lens is set to AF and not MF.Īutofocus offers two distinct modes, which you need to set on the camera.
#FULL SENSOR CAMERA TO VRAY SETTINGS MANUAL#
There are some situations where manual focus is the better option, which we'll come onto later. The first thing to decide is whether you want to use autofocus or switch to manual focus. So which focus modes should I be using, and when? SEE MORE: 9 situations when autofocus will fail you You need to make that you've selected the right focus mode in order to stand a fighting chance of getting a sharp action shot. Moving subjects can present a significant challenge to an AF system too. If there's anything in front of the subject, such as a window or the bars of a cage, chances are the camera will focus on that instead. In these situations, the lens will focus back and forth, hunting for something to lock onto. There won't be any clear edge for the AF system to find. Your camera can struggle to autofocus when there's not enough light or when it's faced with a low-contrast or uniformly coloured scene, such as a brown dog in a muddy field. In what sort of conditions is autofocus likely to get it wrong?

Don't get us wrong: today's DSLRs and lenses can focus faster and more accurately than they ever could but, as with metering and exposure, you need to be actively involved in the process to get the best results.
