Canon PowerShot S400
4.0 megapixels (effective); 3x optical zoom/3.6x digital zoom; autofocus only; program exposure only; JPEG format only; ISO range 50 - 400; proprietary Lithium-Ion battery; movie mode with sound
The immensely popular Canon PowerShot S400 packs 4 megapixels and a 3x optical zoom into a body little bigger than a deck of cards. Though it offers higher resolution than the other digital ELPH cameras, the S400 has fewer manual controls than its predecessor, the 3-megapixel S230. For photographers who value size over features, however, the top-notch images produced by this camera should more than make up for the limited manual controls.
