Performance
Performance is mixed with the IXUS 980 IS, but
respectable overall and generally better than its predecessor. From off
to first shot takes nearly 2 seconds, which isn't great and slower than
before. At between 0.5 and 0.6 seconds under most conditions, shutter
lag is pretty good, and its typical shot-to-shot time is on par with
the category at 1.9 seconds. Turn on the flash though, and you'll be
waiting 3.6 seconds between photos. Continuous shooting averaged a
decent 1.3 frames per second.
Photo quality is consistent with other Canon IXUS-series cameras: excellent. Colours are accurate and well saturated, and exposures tend to be accurate, even in some tough situations. Canon does an excellent job of keeping ISO noise under control through ISO 200. At ISO 400, noise becomes noticeable on monitors, but shouldn't cause problems with prints and doesn't cause any noticeable loss of shadow or fine detail. At ISO 800, noise becomes much more noticeable and some, though not all, shadow detail is lost while most fine detail remains. You should still be able to get decent prints, especially at smaller sizes.
At ISO 1,600, however, noise becomes very heavy and most shadow and fine detail is lost. Our problem is that, again, the IXUS 870 IS produces equally excellent photos with its 12-megapixel resolution. The 15-megapixel sensor doesn't seem to be offering up any added value. Also, the lens exhibits noticeable barrel distortion on the left side.

Conclusion
In the end, there's nothing seriously
wrong with the 980 IS, particularly if you're buying it for the photo
quality and its compact design. On the other hand, most, if not all,
the Digital IXUSs offer similar quality. The Quick Shot mode turned out
to be more useful than we initially thought -- you just have to be
aware that the viewfinder isn't giving you nearly 100 per cent of the
picture. And unless you really want the limited manual options and a
viewfinder, the 870 IS is a better option.
