We use Media Composer 5 here with t2i cameras and yes you can import the native files, but we prefer to transcode all our t2i footage to uncompressed DNxHD using Mpeg streamclip. Also that is the only time consuming step, since we link to the footage using AMA, (avid media access) which is instantaneous. The avid workflow is solid for the DSLR.
By the way, you can get Media Composer 5 for $295 as a student or educator. Try find Final Cut for that price. :)
