How to Set the Autofocus Area on a Nikon D40x

The D40x supports the use of interchangeable Nikkor lenses.

Although the Nikon D40x has been discontinued by the manufacturer in favor of newer models, it is still used by many amateur and professional photographers around the world. In a camera as advanced as the D40x, however, the sheer volume of features can be difficult for a new user to navigate. The advanced focus capabilities of the D40x include three individual focus areas.

Instructions

1. Choose how the camera selects which objects to focus on. You can choose closest subject, dynamic area or single area. Closest subject mode will simply select the object nearest to the camera. Dynamic area is best for moving subjects, while single area is best for static scenes.

2. Enter your selection by pressing the "Info" button, highlighting the focus icon and choosing the appropriate mode. The menu will read "AF-area mode."

3. Select one of the three autofocus areas you would like to use; the options are left, middle and right. In closest subject mode, your choice will not affect how the camera focuses. In either of the other two modes, however, your selection will choose the focus area priority.

4. Enter your selection by pressing the arrow keys until the appropriate focus area is selected. Frame your photo and the autofocus will choose the subject closest to the area you have selected.

Tips & Warnings

• You can lock the focus by keeping the shutter button pressed halfway, even if you reframe the shot while it is held.

• None of the selections you make will affect focus if you are in manual focus mode.
