can be selected.

Using the AF point selection screen, you can manually choose a focus point.

When you’ve highlighted the point you want, either press the AF Point Selection

button again, or half-press the shutter button.

If you want to return to autoselect, continue to rotate the Main dial until all

points are selected.

When to Manually Choose a Focus Point

As I mentioned earlier, when using autofocus point selection (which is the only

option in Full Auto mode and the default in Program mode), you must pay atten-

point choices, as can shots of still lifes, such as a picture of a product that you

want to post on eBay. Manual focus point selection can quickly solve all of these
