The iA function includes an AF/AE Tracking feature that tracks a moving subject to make sure that it continues to be recorded in optimal image quality. A new Intelligent Contrast Control, which automatically adjusts brightness to maintain the best possible contrast, has also been added to the five advanced functions from previous models, including Face Detection, Advanced O.I.S., and Intelligent Scene Selector, and each is activated as required by simply pressing the iA button to capture beautiful images under virtually all shooting situations.
