I bought this camera as a point-and-shoot replacement for my old Canon A540 Powershot.
I have had it for a month now and am delighted with it. The Auto setting does most of what I want and the P setting lets me do something a bit more special when I need it.
The f2.8 lens allows me to to do lots of indoor work without flash, giving more natural shots.
The 4x optical zoom range is fine for most practical purposes and with a total of 12.1 Mp the additional digital zoom is OK because there's still plenty of resolution for snapshots despite the reduced number of pixels.
There are loads of additional features - many a bit gimmicky in my opinion, but the ones that I use most are vivid and super-vivid colour that work really well for shots of flowers and scenery. The in-camera cropping feature allows me to crop images without having to use Photoshop or similar. The black and white alternative to colour images is also great for some kinds of arty shots.
The only thing I really miss about my old A450 Powershot is the possibility of using manual focus which can be indispensible for shallow depth-of-focus macro work or portraits.
I should perhaps point out that I also have a DSLR for more specialised work, like astrophotography for instance, but it is a chore to drag it around and this little camera is my constant companion these days.
