Big disappointment for the new compact Canon waterproof, I returned once received and tried. Despite its rugged appearance, from the first shooting photos prove very poor, very noisy, even with flash and outdoors ... What does this has to give by 20 meters background! Very disappointing and surprising for a 12 Mpix camera, the same as its big brother, the Canon PowerShot S110 which at equal resolution takes incomparably better pictures. In the end, the PowerShot D30 is therefore nothing but a gimmick (300 euros anyway). If you want to make beautiful pictures underwater the solution remains to invest in a good compact one hand and in a good underwater housing on the other.
