And there you have it. Another Canon DSLR Camera release. The new Canon EOS Rebel T4i comes with everything we've already come to expect from a typical Canon Rebel camera including swivel LCD screen (it's now Touch Screen LCD with Swipe, Pinch, and Zoom support), but the stand out feature is the continuous Auto Focus in Video mode. That's a first for any Canon DSLR.
Although it can provide continuous Auto Focus to standard EF and EF-S lenses, the best performance happens when used with an STM Lens. With the Touch Screen you can actually drag your focus point around and the T4i will follow. Canon has available the 18-135mm STM Lens with the kit, or the Canon 40mm F/2.8 STM Lens is also available (found here).
