Category: Beginner to Serious Amateur

The Canon PowerShot A640 features 10MP resolution on a 1/1.8 in. image sensor, 4x optical zoom, which covers a 35mm film equivalent focal length ranging from 35 mm (Wide Angle) to 140 mm (Telephoto). It is also one of the few digital camera that still provides a real-image optical viewfinder that works with the 4x zoom.

A High ISO Auto mode will automatically increase the sensitivity (up to ISO 800) so the camera can use a high enough shutter speed to reduce blurring caused by camera shake and subject movement.

The large 2.5-in. Vari-angle LCD monitor swivels to permit shooting from all kinds of different angles, and is especially convenient when doing close-to-the-ground macro photography; it also has a wide viewing angle for comfortable Playback viewing.

Movies can be recorded at VGA 640 x 480 pixels @ 30 fps and can be taken continuously until the clip size reaches 1GB or the clip length reaches 1 hour. Macro mode allows you to shoot a subject when the distance from the front of the lens to the subject is 1 cm (0.39 in.).

FlexiZone allows you to move the AF frame manually to the desired position. This is convenient for focusing accurately on an off-center subject.

The Canon PowerShot A640 has full exposure flexibility and is feature-packed. It will grow with you as you learn more about digital photography.
