Cons: Get flash and exposure compensation buttons mixed up, Batteries fall out when accessing SD card, No image stabilization

Cons: Some fringing, No image stabilisation, Poor battery life if using with alkaline cells
Summary: Canon PowerShot A640 verdict
Like many new compacts this year, the PowerShot A640 is basically an enhanced version of an earlier model. Since its predecessor was the award-winning A620 though, this is no bad thing.
Pros: Very high resolution images at low sensitivities, 4x optical zoom slightly longer than rivals, Large flip-out screen and optical viewfinder, Full manual controls and decent grip
Cons: Relatively large and heavy for a compact, Screen is low resolution for its size, No live histogram facility, Rechargeable batteries not included
Summary: The PowerShot A640 and digital cameras are equipped with high resolution 10.0 and 8.0 Megapixel CCDs respectively. Both cameras feature the same body design, high-quality Canon 4x Optical Zoom lens, optical viewfinder as well as a 2.5-inch Vari-Angle LCD screen.
Conclusion: My first digital camera came from the Powershot A series and I would be more than happy to own the Canon Powershot A640. The cameras in this range offer a lot of features and great photo quality for the price. The A640 upholds the reputation and is a fine camera. Recommended.
Pros: Sharpness of the photos, Indoor photo quality, Feature set at reasonable price, Angle of LCD screen can be varied
