Now who hasn’t been in this situation before… you spot a photo worthy moment, you run for the camera, frame the shot… and the camera keeps attempting to focus on something other than your chosen subject. It’s so frustrating!
But you can control it, and it’s a total game changer! This simple technique is one of the “a-ha” moments that our students rave about during our Enthusiast Photography Course as really improving their images.
The camera insists on focusing on the same thing – the wrong thing – every single time. See below for a perfect example I prepared earlier!!
The problem lies in the fact the focus point system is set to auto select… which means the camera will decide for you.
You do you have the ability to control which object you want to focus on, by telling the camera which point to use.
Most cameras offer a range of focus points in an arrangement similar to this. Some cameras have more, or less.. but essentially you can use one of those single points rather than just the centre point, or rather than letting the camera choose.
Firstly, you can’t control this when you’re shooting in auto… so select either TV, AV or Manual mode to start with.

Switch then camera to manual focus point selection. As cameras vary from model to model, you’ll need to check your user guide to find out how to switch over.
Then, locate your AF point selection control button/dial. It’s usually the scroll dial or the control arrows on the back of your camera, but if you can’t locate it, once again check your user guide.
Once you’ve done that, you’re ready to scroll around your AF points and choose one. Half depress the shutter button, and you will see the grid of AF points appear on the LCD screen and through the viewfinder. You can then scroll through those points either on the LCD screen, or whilst you’re looking through the viewfinder and choose the AF point you want to use.
You should choose the one that is on or nearest to the point in your frame you want to focus on.
This does take practice, so don’t get frustrated if you don’t master it straight away.
Spend a few minutes playing and becoming familiar with how it works, because once you are able to do this you’ll find you have a lot more creative control over your compositions. And you won’t be missing shots because you can’t get the focus you want!
Once you get used to how to change it, you’ll be able to do it quickly as you shoot with your eyes closed. Or preferably, with your one eye open and looking through the viewfinder as you frame your subject, choose your AF point, and shoot!
You may have noticed your camera offering a choice of AF Drive Modes, these are simply different ways the camera obtains focus.
One Shot (Canon) or Single Servo (Nikon). This drive mode is best suited for subjects that are stationary. When you press the shutter button halfway, the camera locks focus and the AF point will light up and beep. You can use this mode to focus and recompose (see below).
This is the setting I leave my camera on, because it works for most situations.
AI Servo (Canon) or Continuous Servo (Nikon). This drive mode is used for shooting fast moving subjects when the distance between lens and subject keeps changing. Whilst pressing the shutter button halfway, as long as your subject remains covered by a point, the camera will continuously work to bring your subject into focus as it moves. When using this mode, you will not see a point light up or hear a confirmation beep.
AI Focus (Canon – Nikon doesn’t have this). This drive mode is best suited for subjects that may move a little. Once you focus on your subject, if it moves toward you or further away from you, the movement will be detected and AI Servo will kick in. You will hear a low continuous beeping as the camera attempts to refocus. The confirmed AF point will not light up again once focus is achieved. When this occurs be sure to check focus has locked on your subject and not elsewhere. I find this drive mode a little unreliable and requires monitoring.
This is an alternative to toggling around your AF selection points, and one that I use myself quite a bit myself. You would use this when:
Only use this when your subject is not moving at all.
Focus should remain locked on your chosen location. However…
It’s critical at this point to ensure you and your subject do not change focal planes. That means that neither move either forward or backward, and this is especially important when shooting at shallow apertures as you have such a small area of focus in front of and behind your subject.
Another way to control focus is by using back button focus. This is the same as focus recompose, but allows you to lock your AF point use a button other than the shutter release.
