Pros
Pro Continuous AF for video
650D has a hybrid sensor that combines contrast detection autofocus and phase detection autofocus. For continuous AF tracking while filming the camera first approximates the focus using phase detection, then uses contrast detection to more accurately adjust the focus.
Pro Magic Lantern support
Magic Lantern is a firmware add-on that extends camera's functionality by adding a wide variety of features including the ability to adjust white balance by Kelvin scale, Zebras for over and under exposed areas, focus peaking, RGB histogram, and many, many, many others. The software is open source and available for free.
