The camera works flawlessly in its Smart Auto mode. Most of the target audience of this camera would prefer use in this mode and Canon does not disappoint at all. The camera more often than not sets itself up quite accurately and takes sharp photos. The camera still allows flash control in its full-auto mode too, which is quite commendable as well as very useful.
I must mention the Colour Accent mode, wherein one can choose to accentuate a single colour and have the rest of the photo in Black and White. Do try it out and you'll be amazed at the fun results it offers. As with all its cameras, the colour is sharp, deep, vivid and quite accurate without too much digital processing.
The use of Digic 4 processor shows in its agility and response time, which is quite impressive.
Initially, the 4X zoom might seem as too less for a camera of such calibre, with rival companies offering up to 8X. But I promise you it'll only be an initial reaction. The lens is so perfect it offers fantastic image quality right through its zoom range, making it an extremely usable one. Far better than to have more zoom which is not usable in real conditions.
The Image stabilization, needless to say, works flawlessly, as we've come to expect from every Canon. Noise is evident at ISOs higher than 400, again, as expected from this segment of tiny sensor cameras. But I guess one can get away with it upto ISO200, which is again quite good.
Colour reproduction is punchy and aperture of up to f/2.8 can be used at wide angle.
