There wasn't much reason to upgrade with last year's T3i, but that's certainly not the case with the Canon EOS Rebel T4i. This new entry-level DSLR packs a redesigned 18-megapixel APS-C CMOS sensor with brand-new focus capabilities, enabling the camera to use both phase- and contrast-detection autofocus when paired with one of two new STM lenses. The center portion of the sensor uses traditional phase-detection technology, while points nearer to the perimeter aid by recognizing contrast in a scene, enabling a more accurate autofocus technique for both stills and video shooting.
