Pentax Optio SV
Like others in the Optio S series, this five-megapixel model is packed. It squeezes in a 5X zoom with a focal length range equivalent to 36-180mm (f/2.8-4.7), yet the lens retracts so it's flush with the body-one that's just a bit too big to fit into an Altoids tin. A dozen scene modes include settings for subject matter like flowers, surf & snow, and even museums. And its 3-D mode gives you on-screen guides to shoot a stereo pair that will print on 4x6.
