|For smooth operation and flexibility needed for creative expression, the EOS 400D DIGITAL has a 9-point AF sensor that enables fast and high-precision focus detection plus enlarged subject coverage. Convenient cross keys provide fast and easy AF point selection. For more accurate shooting and additional flexibility, focusing points are in a diamond-shaped layout with a central AF point offering cross-type focusing, regardless of lens brightness. In addition, higher precision focusing is possible when using lenses brighter than f/2.8. Such variable focusing enables quick adjustment for a variety of compositions and shooting situations.
