Manufacturer's description

The PowerShot A640 bursts with creative options. Use its 10.0 Megapixels to shoot poster size prints with fine detail. Discover new possibilities with the vari-angle LCD and optional accessories.

Print high quality poster size images with all the incredible detail of 10.0 Megapixels. Crop and trim to create new compositions while keeping your photos extra large and razor sharp.

A 4x optical zoom lens gives you the flexibility to frame shots up close or at a distance without sacrificing quality.

The large 2.5" Vari-angle LCD twists in all directions - ideal for self-portraits and creative shots at unusual angles. Night Display mode aids visibility in low light while a selectable Grid Line display helps with composition. A useful 3: 2 ratio overlay indicates the printable area for standard photo prints.

Canon's DIGIC II image processor manages all camera functions and processes images at high speed for excellent responsiveness and extended battery life. iSAPS is a built-in assistant that uses scene information to optimize camera settings before the shot is taken.

Rely on 9-point AiAF to keep even off-center subjects sharply in focus or use FlexiZone AF/AE to manually select a focus point.

21 shooting modes include a full creative zone for manual control and 10 Special Scene modes for tricky lighting conditions including Snow, Beach and Underwater. My Colors allows color effects to be applied to images and movies.

A high-speed ISO 800 setting allows you to shoot correctly exposed images in low light conditions without using a flash. ISO 800 also enables shooting at higher shutter speeds reducing the risk of image blur.

Safety Zoom offers extra zoom magnification without affecting image quality. Use the Digital Tele-Converter for extra reach on every shot - just like adding a teleconverter lens to the camera.

Focus as close as 1cm and capture all the intricate detail of tiny subjects.

Shoot extra long 30fps VGA quality movies with full audio. View them on the camera's LCD screen or connect to a TV or PC for full screen playback.
