Just Posted: Our review of the Canon PowerShot S100. The S100 is the latest in Canon’s range of pocketable photographer’s compacts, building on the success of the popular S90 and S95. This most recent model offers a more ambitious 24-120mm equivalent, f2.0-5.9 zoom in front of a Canon-made 12MP 1/1.7″ type CMOS sensor, marking a much bigger advance than in the last update. Is it another step towards the perfect pocket shooter or has the camera giant over-reached itself? Find out in our review.
