Like all of Sony's Cyber-shots, the DSC-S70 uses a long-life InfoLithium battery for power, and stores images on memory sticks. The camera's CCD sensor has an impressive 3.3-megapixel resolution and produces 2,048 x 1,536 images. To ensure the highest possible image quality, Sony has opted to use lenses made by Carl Zeiss, one of the most highly respected names in optics. Other useful features include a 3x optical/2x digital zoom lens with macro mode, USB image transfer, aperture priority and shutter priority modes, manual focus option, 60- second MPEG movie mode, and video output.
