The PowerShot A640, launched in August, just before Photokina 06, replaces the popular A620 at the top of Canon's increasingly well-specified 'budget' A series range. The new model gets a bit of a facelift (and a new coat of black paint) as well as a bigger screen, major pixel boost (up from 7MP to 10MP) and a few feature tweaks. Otherwise it offers pretty much everything the A620 did; 4x zoom lens, tilt and swivel LCD, full photographic control and optional converter lenses. And like its predecessor, the A640 was launched with an almost identical twin, the A630, the only major difference being the sensor (8MP as opposed to 10MP). Therefore much of what is said in this review will also be applicable to the A630 (we will be adding A630 IQ results in the new year). The A620 was one of our favorite cameras of the last 12 months, and is a tough act to follow. So is the A640 up to the job? Let's find out, starting with the headline features...

The PowerShot A640 is an excellent all round advanced camera. While its features aren't quite as robust as some more expensive models, for this price tag, it's a good buy.

What Digital Camera test review of the Canon PowerShot A640
The A640 has some high-powered tricks up its sleeves
It's not great in low light, but the A640 has plenty of features photographers will love.
The versatile A640 caters to the auteur and amateur alike by cramming DSLR features into a point-and-shoot body. Continuous shooting, manual aperture and shutter speed settings, and the option to add wide and telephoto lenses will help satisfy the pros. But it’s also equipped to guide a budding Diane Arbus with a super-intuitive menus and […]
