“In the year or so since the SD400 arrived the ultra-compact market has inevitably moved on, with features such as image stabilization and high ISO starting to appear (though it must be said the latter is rarely any good), pixel counts increasing and prices falling, so can the little Ixus/Elph still compete? It’s a little cheaper than the SD400 was (averaging around $320), and it’s a little better (though the changes are hardly ground breaking), but there are definitely better cameras out there. This is certainly true if you want more manual control or more pixels, and for a similar price the Fuji F10 offers usable high ISO performance. But at the end of the day everything that made the SD400 so attractive as a package is also true for the SD450 - and then some. It’s a beautifully made and reliable point-and-snaper that is easy and fun to use, and one that produces surprisingly good results where it counts, and one that - even with the niggles mentioned above - is perfectly designed to satisfy its target market. And so, despite the tougher competition, the SD450 retains its Recommended tag, albeit with more reservations than the rating given to the SD400.”

The words of Phil Askey at DPReview in his Canon PowerShot SD450 Review.

The Canon Powershot SD450 is an ultracompact, 5.0-megapixel snapshot camera. It has a unique starburst design radiating from the lens ring, and is finished in silver-white palladium plating on stainless steel. As ever, the functionality behind this new Powershot model is as stunning as the camera itself. The cameras leverages DIGIC II processing, and a large 2.5-inch LCD. The Powershot SD450 comes with 3x optical zoom, and offers the same strong performance, unrelenting burst capabilities, and great battery life. If you’re looking for an ultracompact snapshot camera and don’t need manual controls, lots of scene modes, or a powerful electronic flash, this model may lure you into the Canon fold.
