Canon PowerShot SD450 / Digital IXUS 55 – Review @ PhotographyBlog

Mark Goldstein jus posted his review of the Canon PowerShot SD450 / Digital IXUS 55, a 5.0 megapixel point-and-shoot digital camera with 3x optical zoom and 2.5″ LCD screen. He’re what he said about image quality;


“The Canon Digital IXUS 55 produced images of slightly above average quality during the review period. The 5 megapixel images were a little soft straight out of the camera and ideally require some further sharpening in an application like Adobe Photoshop. The Canon Digital IXUS 55 dealt well with chromatic aberrations, which only appeared a few of the test shots – limited purple fringing effects could only be seen in high contrast situations. Macro performance is above average, allowing you to focus as close as 3 cms away from the subject. The built-in flash worked well indoors with virtually no red-eye and good overall exposure.

The Canon Digital IXUS 55’s main drawback in terms of image quality, however, is noise. The 1/2.5 inch, 5 megapixel sensor used in the Canon Digital IXUS 55 produces noisy images even at the slower ISO settings. ISO 50 and ISO 100 look fine, but there’s already a lot of noise at ISO 200, which isn’t exactly a quick speed, and ISO 400 is virtually unusable.”
