![]() This can be really disconcerting, because the focus point will seem to move by itself-and usually at the wrong time. There have been times when I have changed the focus point by mistake with my cheek as it pressed against the back of the camera. On some cameras, you can also lock the AF point selection control so that it doesn’t move inadvertently, as illustrated on the Nikon D750 in Figure 4.6. Some higher-end professional models feature a dedicated AF point control that acts like a miniature joystick, enabling you to quickly change focus points, but you can still use the four-way rocker switch on these models as well. ![]() Figure 4.5 shows the rocker switch on the consumer-level Nikon D3200.įigure 4.5 The Nikon D3200 rocker switch on the rear of the camera controls the focus point. For example, if you keep pressing to move the point right, it will go across the viewfinder to the right edge, then reappear on the left edge to start over again. Press the switch to move the selected AF point up, down, left, or right, and you can even set it to make the point wrap around. The active, selected point will be highlighted in red. Nikon positioned it where your right thumb would naturally rest when holding the camera, making it easy for you to move the focus point while looking through the viewfinder. On the Nikon DSLRs, you control which focus point is used via a rocker switch on the back of the camera. For right now, however, set your camera to use a single AF point and practice changing which AF point is selected. In the next chapter, I cover using AF groups, which use one or more of the autofocus points. Read the camera manual for your camera on how to select which is the active point. To be a better photographer, you must be able to select the focus point you want, so you need to practice controlling which AF point is active. There will be a control on the back of the camera that will allow you to change which AF point is active. All you need to do now is place any of the AF points over your subject, make sure that the AF point is active, then press the shutter release halfway down to activate the autofocus.Įach camera model has a different way of moving the selected AF point, but the basics are the same. Having multiple focus points allows the photographer options in composition. Photographer's Guide to Focus and Autofocus, A: From Snapshots to Great Shots
