The EOS Rebel XSi has a high-precision 9-point wide area AF sensor for fast, accurate focus even in dim lighting. It has a number of focus modes, including One-Shot AF, AI Focus AF, AI Servo AF and Manual. In Live View Function, the EOS Rebel XSi has two AF modes: Quick mode, which uses the camera’s standard 9-point AF system, and Live mode, which is a contrast-based AF system that reads the sharpness of subjects right from the imaging sensor, and can be overridden by pressing the AF mode selection button. A familiar feature in PowerShot cameras, Live mode AF uses similar technologies to achieve focus, while Quick mode is more appropriate for capturing action or for shooting in low light.

I absolutely love this camera. This is my first SLR camera and I have learned so much experimenting with it. I am amazed at the quality of photos that even a novice like myself can obtain with it. Very user friendly. Only thing it is missing in my opinion is not video capable.
