The EOS 50D has a new Creative Auto mode and a quick control screen that helps novice users narrow the gap between fully automatic and manual control. While the camera will remain by default in fully automatic mode, frequently changed settings like flash, exposure compensation, image quality and more are all accessible through one easy screen interface designed for intuitive, quick action. A provided shooting guide serves as a quick reference for on-the-fly operation.
