Auto focus on DSLR: Nikon D7000 and Canon EOS 7D

In order to optimally use the autofocus system of DSLR cameras such as the Nikon D7000 or the Canon EOS 7D, you should use the various AF points.

Single point AF or focus on group of points?

• To do this, set your camera to »Single point AF« and use the directional pad or the joystick to select the field in front of your subject.
• Models like the Nikon D7000 or the Canon EOS 7D offer another useful function: With these SLRs it is possible to select a group of points in addition to a single point. This makes it easier to focus on moving objects even if they are not exactly in the desired section of the image.
• Under difficult lighting conditions, however, you should choose the middle focus field for entry-level SLRs, because this is often the only cross sensor of the camera.

Adapt autofocus to the subject: static or moving?

• Modern autofocus systems generally work very reliably. In order to always achieve the perfect result, you should adapt the AF mode to your subject. For static subjects (people and objects) use single-frame AF (Canon: »One Shot«, Nikon: »AF-S«). The best way to snap moving subjects is with the »Servo-AF« (Nikon: »AF-C«).
• Usually your camera will focus as soon as you press the shutter button halfway. However, if your object moves quickly, it is often not easy to bring focusing and triggering under one roof. In such situations, it makes more sense to focus on another button using the camera menu. Many models offer the option of placing the autofocus on the »AE Lock« button on the back of the camera. You can focus with your thumb and trigger with your index finger.
