The T3i uses a 63-zone, double layered metering system and has 4 metering modes. In Japan Canon markets the T3i as the Kiss x5 and elsewhere in the world it's known as the Canon EOS 600D. You can double your battery capacity and improve camera functionality when shooting in vertical "portrait" orientation. One of the other interesting accessories to consider is the Canon BG-E8 Battery Grip. If you like the idea of using an external flash, the rebel T3i lets you control flash units remotely. There are a ton of Canon Rebel Accessories available too. The Canon T3i also has 2 to 10 second self-timer modes and an infra-red (IR) remote control mode. That's not as good as a pro sports shooter might need, but it's pretty good for the average soccer mom or Little League baseball parent to get some good shots of their kid swinging the bat. The independent tests confirm that's about what you get. The Rebel T3i is rated at achieving 3.7 frames per second when set to continuous shooting mode.
