On the other hand, we're a bit more skeptical about the Canon D-series link, if only because a 45x zoom makes almost zero sense in an underwater camera. As anyone who's shot underwater knows, light dropoff happens extremely fast, and anything beyond just a moderate zoom become almost impossible to see. However, a tough superzoom does make some degree of sense—as does using this folding optics to just shrink down the size of the superzoom all together. Think about the Sony T-line of cameras, which were incredibly thin. If Canon could squeeze a 45x zoom into a body the size of its current 20x compact zoom cameras, that would be a major selling point.
