At ISO 400, where most compacts start to run into trouble, both Canons are looking considerably less refined. Overall the images still look okay but a close look at any of the detail shows that luminance noise is starting to add a slightly grainy appearance to things. There isn't much in the way of chroma noise (the black areas have remained neutral, for instance. However, the level of detail is considerably lower than in the ISO 80 shots, showing that the low levels of chroma noise are the result of noise reduction averaging and smudging the colors to avoid odd patches of aberrant color. That said, the A720 IS would produce a perfectly decent print at ISO 400 as long as light levels hadn't dropped too far.

The A720 IS improves, albeit marginally, on its predecessor, in spite of each pixel being that tiny bit smaller and hence receiving slightly less light.
