A review of the Canon PowerShot SD450 digital camera, also known as the Canon Ixus 55, is available at PhotographyBlog.

The review conclusion:
“On paper it doesn’t seem to offer anything different to a lot of other, cheaper cameras - 3x optical zoom lens, 7 megapixel sensor, large 2.5 inch LCD screen - but pick the IXUS 55 up and there is an undeniable sense of quality which far exceeds the competition. Just as impressively, Canon have managed to include a large LCD screen and small optical viewfinder despite the tiny dimensions of the IXUS 55.
Unfortunately image quality isn’t quite up to the high standards set by the rest of the camera. Due to the small 1/2.5 inch CCD, the 5 megapixel images are noisy at ISO 200 and 400, and they are also a little soft out of the camera with no option for increasing the sharpness level. If you want a camera with similar build quality that is also pocketable but with better image quality, I would suggest that you take a look at the slightly bigger and more expensive IXUS 750.”
