The Canon Digital IXUS 90 IS is in the middle of the latest trio to join the ever-popular and ever-stylish IXUS range. The question is, as ever, whether these cool kids of the compact camera world are just a severe case of style over substance.

Our first impressions of the classy exterior are good, but how long will they last when we take the 10-megapixel camera out to test?

Design

As always, Canon doesn't disappoint us on the styling front. The IXUS 90 has a retro, boxy feel, but with angled elements to give it a modern twist. The inflexible metal frame and clean lines radiate understated élan. The lens is flush-folding, and the rear of the camera sports a large 76mm (3-inch) screen. If we had a quibble with the design, it's that the symbols on the controls look cluttered.

The controls themselves are unusual. Instead of buttons, areas of the frame flex when pressed. There isn't quite enough flex to give satisfying tactile feedback, but it's still interesting.

The IXUS 90 uses a scroll wheel that also functions as a clickpad. The action, initially at least, is stiff. The similar-sized wheel on some Nikon Coolpix models has ridges that are easier for the thumb to push against, while the IXUS 90's tiny raised goosepimples afford less traction. We like scroll wheels as it is a quick and easy method to switch modes, as well as providing access functions like panorama stitch assist and color filters. But Canon needs to tweak the design slightly.

Features

Again, the IXUS range is more about good design than ground-breaking photographic innovation. True to form, the specs and feature set of the IXUS 90 aren't particularly exciting. The lens has a distinctly average 35-105mm-equivalent focal length, with a 3x optical zoom. The usual compact whistles and bells are included, such as face detection, a self-timer and video recording. We don't mind Canon leaving out an internal memory: They're usually so meager as to be pointless.

One big plus is the inclusion of optical image stabilization to combat image blur caused by shaky hands. It's possible to check focus before and after an image is captured, with the center of the image enlarged in shooting mode and the option to zoom in on the resulting image in playback mode.

While in playback mode, images can be resized and cropped in 2-megapixel increments down to VGA size. Images can be tagged with the "My Categories" function. This offers preset tags like People, Events, Sport or three generic tags. Sadly, these blank tags cannot be customized by the user.

Performance

We found the autofocus on the IXUS 90 to be fast and decisive. The onscreen focus zoom, which magnifies the center of the screen, really helps in this regard even if it does take some getting used to.

The IXUS 90's speed is adequate. Startup is close to instantaneous once you disable the Canon-branded startup screen, but shot-to-shot time is an uninspiring 3 seconds. The burst mode ticked along at a steady if underwhelming shade over one frame per second, but that kept up for a worthy 15 minutes with no sign of stopping. With more than 1,200 images and counting, the IXUS 90 looked set to fill the 16GB Kingston SDHC card we were using, although the battery indicator was flashing rather urgently by that point.

Image Quality

Images come out generally crisp and colors are accurate. Predictably, image noise is a big problem in high ISO mode, completely negating its usefulness for low-light shooting--and best avoided. Noise at ISO 1,600 isn't much better, but at a sensitivity of 800 and below, you'll find it's well-controlled without too much smearing of detail.

The Canon Digital IXUS 90 IS is a worthy addition to the IXUS lineup in that it's every bit as stylish as the brand requires. Despite a paucity of features, the IXUS 90 feels substantial, thanks to its sturdy build, quirky controls, large screen and respectable picture quality. Still, it doesn't do much to shake our nagging feeling that the IXUS range demands a price premium for style and branding rather than outstanding qualities. There are other point-and-shoots around with extra attributes that give them the edge, like the Sony Cyber-shot DSC-W130's longer lens or the Samsung L830's manual controls. Still, there's something about an IXUS that's hard to resist.
