Reviews Word on the street

Rebel T4i  vs EOS 5D Mark II 

It is essentially a simplified Aperture Priority mode, giving you the options to choose between a blurred and sharp background and a darker or brighter image.
EOS 5D Mark II

It has a 24.6-megapixel CMOS sensor, built-in sensor-shift image stabilisation and sensor cleaning, 5fps shooting in Raw+JPEG mode, a tough weatherproof body and what is widely acclaimed as the best viewfinder on the market.
EOS 5D Mark II

Many of the new capabilities definitely target pros: a pair of low-resolution raw formats (10 and 5.2 megapixels), more interchangeable focusing-screen options, in-camera peripheral-illumination correction to compensate for brightness nonuniformity across the image, and a silent Live View mode.
