Compared to...

Below you will find a studio comparison between the Canon PowerShot SD300 and the similarly specified Casio QV-R40. We have included samples for the lowest and highest ISO settings for each camera (50 and 400 for the SD300, 80 and 320 for the QV-R40).

Nice, clean shots from the SD300, with typical Canon color and a surprising amount of detail. It's nice to see noise so well controlled without the obvious use of heavy NR. It's also worth noting that even stopping down to F4.5 (admittedly not something you can actually do yourself as the SD300 is an auto only camera) reduces - though doesn't entirely remove - the edge softness seen at F2.8 The SD300 and QV-R40 are capturing roughly the same amount of detail (though the Canon does better in the center of the frame, the Casio does better at the edge), but the Casio's harsher in-camera sharpening is obvious, as is the slightly higher noise.
