Canon PowerShot A20 Review
At PMA 2001 this year Canon announced two new PowerShot cameras aimed at the entry level market, the A10 and A20, based on the same body, system, 3x zoom lens and body design, they differ only in their resolution (and price), the A10 has a 1.3 megapixel sensor and a retail price of US$400, the A20 has a 2.1 megapixel sensor and a retail price of US$500.
Canon PowerShot A20 vs. Canon Digital IXUS 300
Obvious comparisons will be made drawn between the Powershot A20 and it's more expensive brother the IXUS 300 which also features a 2.1 megapixel sensor and 3x optical zoom lens. Here's a specifications comparison table for the two.

As you can see the two are virtually identical, the IXUS 300 has a few advantages over the A20 which may justify its higher price, we can also expect the price difference (street price) between the two to be greater than US$100 by the time they hit the market.
NOTE: As the A20's onboard software is identical to the IXUS 300 we have re-used the LCD captures from that review (except the movie mode which doesn't exist on the A20).
If you're new to digital photography you may wish to read the Digital Photography Glossary before diving into this review (it may help you understand some of the terms used).
Photographs of the camera were taken with a Canon EOS-D30, images which can be viewed at a larger size have a small magnifying glass icon in the bottom right corner of the image, clicking on the image will display a larger (normally 960 x 720 or smaller if cropped) image in a new window.

DPReview calibrate their monitors using Color Vision OptiCal at the (fairly well accepted) PC normal gamma 2.2, this means that on our monitors we can make out the difference between all of the (computer generated) grayscale blocks below. We recommend to make the most of this review you should be able to see the difference (at least) between X,Y and Z and ideally A,B and C.
