Sony’s DSC-P52 Cyber-shot® digital still camera proves that price is irrelevant where Sony quality is concerned. Providing great value, you’re getting a camera with functionality that rivals more sophisticated models. The DSC-P52 offers 3.2 megapixel effective resolution, 2x optical zoom, 0 to 3.2 Smart Zoom (at VGA size), and Sony features that make it easier than ever to take exciting digital photos with point-and-shoot ease.

From 16-frame multi-burst, MPEG movie modes, and smart auto-focus functions to an intelligent flash, multi-pattern measuring and voice memo and e-mail modes. The DSC-P52 also includes a USB 2.0 interface and convenient rechargeable NiMH batteries with included charger.

digital Zoom "zooms" as it sacrifices the resolution of the photo. Just like u select a part of photo with Photoshop and enlarge it.  So it will be seldomly used.

Digital zoom is something you've probably heard a lot of, especially on fixed lens digital cameras. Certain manufacturers are famous for silk screen printing "6x zoom" on the side of the camera when truly the camera is fitted with a 3x optical zoom lens and can optionally provide 2x digital zoom.

Optical zoom is produced by the lens system and is the magnification difference between minimum and maximum focal lengths. Depending on which side of the fence you stand digital zoom can be seen as a useful addition to a limited zoom capability or at worst a marketing ploy to sell limited zoom cameras.

The truth: Digital zoom is simply the cropping of a center part of the captured image. Imagine seeing the whole scene (as below) and then progressively shrinking a box into the center of the image, if you were to crop that box out of the image you would in effect have a "digital zoom".
