Canon PowerShot A640 Review
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...
- 10.0 million effective pixels
- 35-140mm (equiv.) 4x zoom lens

- Digital Tele-Converter and Safety Zoom
- 2.5-inch vari-angle LCD and real-image optical viewfinder
- 21 shooting modes

The size of the models at the top of the A series tree has been creeping up since the A95, and the A640 is a little wider than the camera it replaces. The biggest physical change (aside from the new paint job) is the larger screen, which has jostled all the main controls over to the right. To compare the A640 and A620 rear views just move your mouse over the image below.
