This camera is compact, light but feels good quality build.
It has easy to use manual functions and a good ISO range of 80-800.
I have taken shots in a variety of lighting conditions and it performs very well.
The depth of field is excellent, which you would expect with compact lenses, but compared to other cameras i have the Canon is sharper and retains excellent contrast and colouring in your backgrounds when shooting in good outdoor light.
Shots taken indoors without flash, on Auto ISO setting,were excellent. It fits nicely in the hand and all the controls are accessible when you get used to them without taking your eye off the subject. On a 2GB SD Card, on full resolution, the camera will take 647 shots, which should be ample for most people.
The 2" LCD screen is also very good and is viewable in all but the brightest light. The 4x Optical zoom is a good feature, but forget about the digital zoom, as it reduces the quality of the shots significantly (as with most cameras) and is a waste of time.
The video capture function has 3 settings, fast capture for sports and action (60fps), standard for normal conditions (30fps) and compact, for sending as an e-mail file or viewing on a small screen (15 fps).
The sports mode is good, but disables the zoom function. Standard mode is best and still allows you to zoom in and out from your subject. The compact mode is around the quality you would expect from the average mobile phone and is a little pixelated when your subject starts moving.
Sound is recorded in mono but is good quality and the camera picks up sound well, even when used outside.
The movie capture in standard mode is the best compromise and provides good quality (similar to the old 8mm camcorders) which is viewable on full screen when played back on your PC screen at good quality, and acceptable quality on a normal TV when played back using the lead provided (just be sure to change the settings to PAL not NTSC if playing througha standard UK TV).
I understand there are a number of teleconverter and telewide converter lenses for this camera which will increase the zoom or give a wider angle of view respectively. The ones i have looked at though, made by Canon are expensive at £100+. I expect that they will be of superior quality though, but if you are to spend that sort of money it would be better to look further up the powershot range for something to take serious hobby shots without having to lump an SLR or large bridge camera about.
At between £100-£150 to buy, i think this camera is a bargain, and is ideal for either the keen amateur / pro user as a convenient, great quality pocketable compact, or for the novice user who just wants to point and press and achieve good results. Highly recommended.
