Yes. The XTi has 25% more pixels, effectively minimizing noise. Plus, the sensor is a generation newer than the 30D so it should have better noise-reduction technology. Unfortunately, we didn't do a pro review of the 30D so I can't pull up back-to-back studio tests. But I bought the XTi over the 30D because of the price and the extra resolution. I think it was a good decision.Originally Posted by Anbesol
