While video is probably the main application for the SL1’s improved Hybrid AF, I was pleasantly surprised by how well it worked when composing and shooting casual snapshots.

Ironically, this design is more suited to pros who plan to use the camera as a cheap video dSLR and never take it off the video setting than to the consumers at whom it's ostensibly targeted.

Another significant addition is the Wireless Flash option, which allows the camera's pop-up flash to be used as the master for other Speedlite flashguns.
