Sony A57 VS Canon T4i (650D)

I compare the Sony SLT-A57 to the Canon Rebel T4i (650D). Both cameras are very similar in terms of still capabilities, the Sony is 16 MP and the Canon is 18 MP. Both cameras have an ISO range of 100 to 25,600 ISO. The T4i (650D) is the first Canon to offer full autofocus in video mode, while this tech works well with existing lenses it works best with STM lenses. For my test I used the 18-135 IS STM, I was not able to detect any noise from the lens during focusing in video mode. It however did not match the speed of the Sony, the Sony however was louder during AF operation.
