I've had Many IXUS cameras and this one is the best - fantastic optical zoom, great picture quality. For the size of a cigarette packet ict brilliant.
Note: Its Slightly bigger than l'autre ixus' I've had, for the purpose 16x Optical lens, icts well worth it. Get some extra batteries N11 ... I did and I still need all 4 weeks for a holiday - a 32Gb card lasts much along than the batteries!
