When you're shooting a moving subjectsuch as a person moving toward you or a flower moving in the wind3D AF keeps it sharp by tracking movement along three dimensions (x, y, and z axes). Then, when you press the shutter, 3D AF compensates for shutter lag with predictive focus control. Autofocusing is ultrafast so you don't miss the momentin Fulltime AF, focusing starts just 0.18 seconds after you touch the grip sensor and Super Fine EVF. As for Single-shot AF, the DiMAGE A2 delivers enhanced precision, even in tricky lighting conditions, with its wide 11-point AF area and advanced subject detection algorithm.

The DiMAGE A2 turns on the speed when you need itto capture a dynamic moment at a sporting event or the fleeting expression of a child, for example. You can shoot 8 megapixel images at a rate of 1.9 fps while 3D AF keeps the subject in focus. For even faster shooting, UHS (ultra high-speed) mode boosts your rate by almost 5 timesat 7 fps, you can capture images in VGA resolution (640 x 480). Anti-Shake stabilizes shooting in UHS mode.

		There are two autofocus modes to choose from. The Single-shot AF mode puts a focus lock into effect once your subject is in focus. Alternatively, the Continuous AF mode tracks a moving subject as you press the shutter-release button halfway. Manual focus can also be selected. With the DiMAGE A2, the camera's CCD automatically turns up the gain in dark conditions.
