Canon PowerShot SD450Canon PowerShot SD450 Digital ELPH /Digital IXUS 55 ReviewSimon Joinson, February 2006

Review based on a production Canon Digital IXUS 55 Announced in August 2005, the SD450 (which goes by the name of Digital IXUS 55 in Europe) is the latest in a long line of ultra-compact ELPH or IXUS cameras stretching back to early 2000 (and a lot farther back than that in the film camera world). Essentially a fairly minor upgrade to the popular SD400 (Ixus 50), the SD450 incorporates two UA (Ultra-high Refractive Index Glass Molded (GMo) Aspherical lens) elements which has allowed Canon to produced its smallest cameras yet to feature a 3x zoom. New features include a larger wide viewing angle 2.5-inch monitor, a direct access ISO button, a nifty orientation sensor that rotates the display of images as you turn the camera round in playback mode and some fancy playback effects. It may be smaller than a credit card, but Canon has still managed to cram a fairly comprehensive range of features into the SD450;5.0 megapixel CCD2.5-inch color TFT monitor35-105mm (equiv.)

Conclusion / Recommendation / Ratings are based on the opinion of the reviewer, you should read the ENTIRE review before coming to your own conclusions.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 (typically VGA) image in a new window.To navigate the review simply use the next / previous page buttons, to jump to a particular section either pick the section from the drop down or select it from the navigation bar at the top.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.
