Although the ISO 1600 setting is obviously a 'stop too far' the ISO 800 output - thanks to Canon's fairly light-handed approach to noise reduction - is surprisingly usable, and is better than a lot of competitors manage at ISO 400. You're not going to want to use ISO 800 for anything containing fine, low contrast detail, but for situations when you simply don't have an option it will produce something still recognizably photographic (as opposed to a fuzzy mess, which is where the ISO 1600 result is headed). As I've said before, the ISO 800 result above is an indication of how far sensor and noise reduction technology has come in the last couple of years, and whilst not a patch on the Fujifilm FinePix F30, it is at least usable at a pinch.
