DPReview is featuring a Japanese shoot-out between the two tiny digicams of the moment, the Sony CyberShot U and the Casio Exlim.
The actual report is in a foreign language of course, but the gallery of photo examples is interesting enough to go on with. For my money there’s not THAT much difference between the two, although the Sony does manage to edge out the Casio when it comes to sharpness.
