Cameratown did an in depth comparison of Canon T2i and Canon 7D.

As a matter of fact, Canon rebel T2i is an entry level digital SLR and it is not in the same league as Canon 7D, Canon’s best APS-C sensor digital SLR.

In early posts, Canon T2i was compared with Canon T1i, Canon EOS 50D, and Nikon D90.  I think these three cameras are closer in features and true rivals.
