Hey! You should know that Canon has released a newer version of this product: the Canon EOS Rebel T5i.
At first glance, Canon's latest highest-end Rebel is a modest ugprade to the T3i, but there are a few subtle improvements under the hood that make this a worthy upgrade. The sensor is still 18 megapixels, but Canon has added crucial phase detection autofocus pixels that will allow the camera to focus full-time in live view and video modes. These abilities are augmented by the release of two new step-focus lenses, the 40mm pancake and 18-135mm kit, that promise fast and quiet focusing. Canon has also upgraded the autofocus to include 9 cross-type sensors, which should offer more accurate focusing, as well as a multi-touch display that borrows the pinch and swipe gestures pioneered by Apple. You don't have to use the touchscreen due to the number of external controls, thankfully, but it's there if you prefer to. Other, smaller changes include a boost to 5 fps burst shooting, the addition of multi-exposure modes like HDR, a stereo mic, and automatic lens correction for Canon lenses. While the new live view yields faster autofocus than the T3i, reviews have found that it still doesn't compare to the mirrorless competition. This is a real blow to Canon, who relied on this new feature to differentiate the T4i from the competition. It's still a great DSLR, but mirrorless is beginning to feel like the inevitable future.
