Our friends over at Popular Photography got a hands-on look at the new Canon EOS Rebel T4i, the sequel to the fantastic entry-level T3i DSLR. It's not wildly different from its predecessor, but with a more powerful processor, a better autofocus (including continuous autofocus in video mode, a great feature), and, most importantly, a very flashy touchscreen interface (including touch to focus and navigation), it's definitely worth a look for anyone considering an entry-level (or even intermediate-level) DSLR. Check out the report (with video of the new interface) over at Pop Photo.
