Sony Alpha 100 vs Sony Alpha 550 (noise)

One huge weak point of the Sony Alpha 100 is the noise. I was expecting the 550 and its CMOS sensor to provide a major improvement to this regard, and was not disappointed.

Here is quick illustration. It’s a typical lowlight situation. Even with an aperture of 2.8, if I want to keep a reasonable exposure time of 1/30, I need 1600 ISO. Here is how the 2 cameras handle the challenge. The pictures speak for themselves.
