On the Maxxum 70, the AF sensor count has been increased to nine for consistently reliable focusing over a wider area of the frame. Drawing on years of experience in auto focusing technology, the new Center-Cross 9-Point system's coverage extends not just vertically and horizontally from the center point, but diagonally into all four quadrants of the frame. The result is sharp focus even when your subject's position changes unexpectedly.Autofocusing speed is one of the Maxxum 70's greatest strengths, so you're always ready to capture those magic moments you want to preserve forever.As an added benefit of the Center-Cross 9-Point AF system, the Maxxum 70 boasts a remarkable new level of responsiveness and auto-tracking ability when subjects are moving toward or away from the camera even diagonally. In addition, a red mark is superimposed on the image in the viewfinder to provide you with visual confirmation of the auto-tracking focus point.The built-in flash has a guide number of 16, and provides powerful illumination with up to 28mm wide-angle coverage. It offers a choice of Auto Flash, Fill Flash and Flash Cancel modes, as well as a Red-Eye Reduction mode that's perfect for parties and indoor events. When used in combination with any of the (D) series lenses, ADI (Advanced Distance Integration) assures proper illumination of your subject even when shooting against a very dark or light background. High-quality materials and construction provide a solid feel with sure handling.
