Canon EOS Rebel T3i has amazing video capabilities, images and video quality. This camera can be very frustration at times. It is hard to shoot fast things such as an impatient child when they're messing around or sports. It's good to take videos, but not as much pictures because it is hard to keep up. The T3 is about $450 but if you have more money to spend you should buy the T3i because of it's video capabilities. It has significantly better performance and photo quality than the T3, and you can get higher resolution, excellent video capture, and an articulated LCD. The Canon Rebel T3i takes the consumer level dSLR a couple steps closer to the mid-level Canon 60D with the addition of the rotating rear LCD screen, remote flash firing, and in-camera processing features. The T3i is heavier than the T2i because it has the rotating rear.
