Bij DPReview is een uitgebreide review verschenen over de Canon Digital Ixus 400 camera (ook bekend onder de naam Powershot S400 in Amerika). Deze ultracompacte camera meet 87x57x28mm en weegt inclusief batterij slechts 222 gram. De camera is uitgerust met een vier megapixel CCD-sensor en een 3x optische zoom. De reviewer is erg positief over het ontwerp van de camera, de resolutie en kleuren van de foto's. Een paar kleine minpuntjes zijn er wel, maar geen van allen noemenswaardig. Phil Askey geeft de camera dan ook de felbegeerde "Highly Recommended"-waardering:
The PowerShot S400 is a stylish ultra-compact, it follows in the tradition of previous ultra-compact PowerShots in being functional, of very good build quality and producing excellent images. The new 'Cerabrite' material used for the S400's case is a bit of a revelation, it looks far brighter and cleaner than the older stainless steel, doesn't show finger prints and is harder to scratch. It will I'm sure look great on the shelves and in the shop windows.
The S400 has a very fast startup time for this kind of camera (extending lens) once you're used to the one second power button 'hold' before it recognizes the power on. Operationally the camera feels responsive and is always ready to shoot, auto focus times are improved if you stick to a single AF area (disable AiAF). Features wise it's good for an ultra-compact although others are coming into the market with more for less money.
