Pro Continuous AF for video
750D uses 19-point cross-type autofocus and 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. It performs well with set AF points for tracking, less so using subject tracking.
Con Dynamic range could be better
According to tests performed by DxOmark 750D has 11.96 stops of dynamic range in print and 11.17 stops on screen for images taken at 100 ISO while cameras in this price range commonly push 14 in print and 13 on screen.
Dynamic range is the range of brightness that a camera can capture. Detail in parts of the scene that are outside of the camera's dynamic range will be lost.
