The 'Elph' series is a line of extremely small cameras by Canon. Originally introduced based on the AFS film format, it now also includes Digital with the introduction of the Canon Digital Elph/Powershot S100! These are tiny metal body cameras, usually around 4-7 oz in weight, and less than 4 inches on their longest dimension...they're quite handy for toting around when walking, or just keeping on you for whatever embarrassing shots of your mates you can get. Outside of North America, this same line is called (I believe) the 'Ixus.'
