The Ixus i7 is an update of the original miniature Ixus known as the ‘i’. As you'd expect, during this review of the Canon Ixus i7 we found that the i7 features a handful of upgrades to bring it up to date – including face detection and a resolution bump to 7.1Mp.
The sensor increase means that the continuous burst has slowed from 1.8fps (frames per second) to 1.6fps, but the i7 still doesn’t place a limit on how many images it can capture in one sitting. Plus, it now records movie clips of unlimited length, right up to a resolution of 640x480. So it’s just as well that one of the other welcome upgrades includes support for higher capacity SDHC (secure digital high capacity) media, for cards greater than 2GB.
While there are some worthwhile upgrades on the inside, the i7's exterior remains unchanged. And this is good news. The Canon is beautifully constructed – its looks will seduce you across a crowded camera shop. Unfortunately, recycling the same exterior means you still get the same small 1.8in LCD, and the same restricted 2.4x optical zoom range, complete with an uninspiring f3.2-f5.4 aperture spread.
When it comes to image quality, the i7 can't compete with its bigger siblings. The main problem is picture noise but, providing the ISO is kept to conservative levels, images stay clean with good detail and balanced colours.
