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 CCD
  • 2.5-inch color TFT monitor
  • 35-105mm (equiv.) F2.8 - 4.9, 3x optical zoom
  • 640 x 480 movies at 30fps
  • Print/Share button
  • Fast Frame Rate movies (320x240 pixels @ 60fps)
  • 'My Colors' feature
  • Seven special scene modes
  • Custom white balance
  • Spot, center-weighted and evaluative metering
  • DIGIC II processor & iSAPS
  • 9-point AiAF
