The latest entry-level PowerShot model from Canon (as of 8/2004), the A400 is a 3.2 megapixel camera that features a 2.2x optical zoom and DIGIC processor for superb image quality. It also includes a high performance 9-point AiAF autofocus system, Intelligent Orientation Sensor, and 12 shooting modes to ensure that it’s easy to take great images, even under challenging conditions. The high quality 2.2x optical zoom lens has a focal length of 45-100mm (35mm equivalent), making the A400 especially suitable for portrait photography. Taking close-ups is also simple with its 2 in. (5cm) macro function.

Review

The A400 (which is available in 4 attractive colors) features the same technology found in Canon’s professional digital compact cameras like Canon's DIGIC processor and iSAPS technology, which enables users to capture high-quality images. The purpose built DIGIC processor integrates all image processing algorithms onto a single chip to deliver fast write times, minimal shutter lag, optimal image definition and consistently precise and natural color reproduction. iSAPS, a built-in photographer's assistant, analyses composition factors such as zoom position and luminosity in order to predict the type of photo being taken.
