Noise 550D vs 500D
Mar 1, 2010

I just got my 550D, and did a few quick test shots of Neat Image calibration target using various ISOs. I shot RAW, converted using DPP 3.80 with all noise reduction turned off, so that sensor noise characteristics are displayed rather than processing done by the JPEG engine. The results are at

The images are out of focus on purpose, so you can concentrate on the noise. I included 500D's results as well (ISO 1600 and 3200) for comparison. It seems 550D is maybe half a stop better (or maybe 2/3 stops, according to noise profile values of Neat Image).
