t4i screen also articulates and has a higher resolution. It doesn't have a a control whell or top LCD and uses an inferior viewfinder, and tops out at 1/4000 shutter speed. Shutter speed doesn't matter to me bc of my 1d2. The ergonomics matter, but I am wondering whether the touchscreen LCD makes up for the lack of control wheel. I am thinking it might. I figure IQ would be close or better for the t4i.
Also, I don't know whether t4i can control as many flash groups wirelessly. I am guessing no, but never use more than 2 anyway.
