'Burst shooting is possible at up to 8.4 frames per second, the fastest of any PowerShot Digital ELPH camera to date.'
'The Canon PowerShot SD4000 IS Digital ELPH sports an f/2.0 aperture, perfect for creating enticing portraits, by drawing attention to the face and blurring the background with its impressively shallow depth-of-field. 720p HD movie shooting capability plus HDMI output.'
'Excellent high ISO performance'
'Being the top of Canon's style compact range, the SD4000 IS also has a selection of extra shooting modes such as fisheye and miniature (mock tilt/shift) modes. '
'the Canon PowerShot S3 IS's combination of features, performance, and relatively compact design certainly gives megazoomers a compelling alternative.'
'S3 shooters have a fast, accurate, and very quiet ultra-zoom digital camera that's capable of capturing reasonably sharp handheld shots at shutter speeds that are beyond the ability of other (non IS) long zoom digital cameras.'
'It offers just about everything you want in a camera, from a big zoom lens to optical image stabilization to manual controls to a fancy movie mode.'
'The S3 IS fit well in my hand and felt sturdy, though it's light and fairly compact.'
