Sony's history of electronic innovation combines with legendary optics from Carl Zeiss to make phenomenal compact digital cameras. The 7.2MP camera has Carl Zeiss optics with a 3X optical zoom (plus a 2X digital zoom). The 1/2.5" Hole Accumulated Diode sensor allows more light to pass to each pixel for increased sensitivity and reduced noise.
Sony's Clear RAW Noise Reduction System aids in cleaning up the picture noise normally associated with high ISO photography. The High Sensitivity/ISO 1000 mode lets you take pictures in low light without a flash to preserve the mood and take great candid shots.
Multiple movie modes including VX Fine let you take 640x480 movies at up to 30fps limited in length only by the amount of available memory. Picture modes like snow and beach allow you get great shots no matter where you are.
