I just opened my XMAS present. I upgrdaded from the original Digital Rebel to a 30D. One thing I noticed right off the bat which I have never seen mentioned is the speed of the AUTOFOCUS. I always thought this was up to the lens but the 30D definitely makes a difference over the Rebel. Definitely worth the upgrade. I am using a Tamron 24-135 lens and it is working better than ever before.
