This tech-speak, says Chuck Westfall, Technical Advisor at Canon USA, adds up to the 50D performing better at higher ISO settings than the 40D, despite the new camera's smaller pixels (4.7µm for the 50D vs 5.7µm for the 40D). Purchasers of the 50D, says Westfall, can expect noise levels to be roughly 1 to 1.5 stops better in the high ISO range. For example, this means that a photo shot at ISO 3200 on the 50D is expected to have similar noise characteristics to one shot in the ISO 1100-1600 range on the 40D.
