Optics and Resolution
With the high-level imaging power of 4.0 effective megapixels (2304 x 1728 pixels), the Optio S4 captures everything from macro shots to distant scenery with exceptional sharpness and accuracy. Other resolution modes include 1600 x 1200, 1024 x 768, and 640 x 480.

Equivalent to a 35–105mm lens in 35mm format, the 3x optical zoom allows a full range of shooting from expansive scenery to telephoto shots. All elements are crafted entirely from glass and two of the lenses are aspherical on each side. Combined with 4x digital zoom, the Optio S4 offers 12x combined zoom capability.

Movie Mode
In addition to taking still photos, the Optio S4 can also record movie clips of up to 60 seconds with audio at 12 frames per second. The limited resolution of your movies guarantees that this feature won't replace your camcorder, but it's perfect for when you just want to capture a quick movie and e-mail it to a friend or relative.

The time-lapse movie function allows a sequential set of shots to be run as a short film. This can be used for impressive effects, such as scenes of clouds rushing across the sky, for example, and offers a selection of recording speeds--X2, X5, X10, X20, X50, and X100.

More Features
With a shutter release time lag of just 0.01 seconds, the Optio S4 allows switching from viewing to shooting with a single touch of the shutter or playback button at any time.

The built-in flash on the Optio S4 can be set to fire automatically when shooting in low-light conditions. For greater control,
