Good first review for the T4i.
The T4i has been reviewed by digitalcamerainfo.com, and it's quite favourable. It looks like Canon has upped their game for the Rebel line.
From Digital Camera Info
In shooting with the T4i, it’s clear that the sum of all those spec upgrades is a camera that truly feels new. That’s a good step for Canon, as we felt the T3i was a lackluster, marginal improvement on the massively successful T2i that preceded it. With the T3i staying in the line as a mid-level option (above the T3 and below the T4i, for now), that separation was necessary for the T4i to be relevant.
