The SX1's noise supression profile is pretty typical: sharpness remains OK through ISO 200 followed by some detail degradation at ISO 400 and general mushiness at ISO 800 and above. However, like most Canons, color noise remains very low across the range.

We rarely get the chance to do an apples-to-apples comparison of different sensors in the same camera as we do with the SX1 and SX10. And it came as quite a surprise that the SX10's color is actually slightly better than the SX1's: the differences in the oranges, yellows, and purples are especially striking.
