Optics
A 3x, 6.4-19.2mm optical zoom lens is built into the P30, the equivalent of a 41-123mm lens on a 35mm camera. In normal shooting mode, focus ranges from 20.4 inches (50cm) to infinity. The Macro mode focuses from 1.2 to 20.4 inches (3-50cm). The P30 offers both automatic and manual focus control, with "manual" focus referring to a series of fixed focal distances accessible through the Record settings menu. Available distances are 0.5m, 1.0m, 3.0m, 7.0m, and infinity. We were especially pleased with the inclusion of an AF assist light, which can be turned off through the Setup menu. The AF assist light is extremely valuable in low-light shooting situations where the camera may normally have trouble focusing. We found it to be very effective in our testing. A set of 37mm filter threads line the inside lip of the lens barrel, accommodating Sony's line of accessory lenses, which can extend the camera's wide angle, telephoto, and macro capabilities even further. Aperture is automatically controlled, with an available range from f/3.8 to f/11.

In addition to the 3x optical zoom, the P30 offers a 2x digital zoom, increasing the P30's zoom capabilities to 6x. The P30 takes advantage of Sony's Precision Digital Zoom technology, which does a nice job of digitally enlarging the image without affecting the quality too much. Regardless, we always like to point out that digital zoom in no way takes the place of true optical zoom, as digital telephoto simply enlarges the center portion of the CCD. This often compromises image quality in the form of softer resolution or higher noise. The P30's digital zoom is turned on (or off) through the Setup menu, and is accessed by zooming past the normal zoom range.
