To fix his choice, there are a number of points, in addition to the price on which to consider:
Size, do you prefer a compact "jewels" or a full-size, bigger but can be
be better in hand.

The possible settings, the number of scenes mode, the manual settings, disabling and
specific flash settings.

Zooming, as a rule, are compact wide angle, ie their purpose allows
to shoot wide shots (landscapes, groups of people, etc.).

So the zoom level that will make the difference. It will be sure to check the amplitude of
Optical zoom (x10 x5 etc., the higher the number, the more you can shoot things
distant). Why focus on the optical zoom? Because it is a clever game with lentils
superimposed on each other within the lens that what we want to photograph far
seems very close. The magnification is mechanical, so there is no loss of image quality.
Digital zoom, it means that the unit will grow each point of the image artificially. such as
a magnifying glass. The picture taken with digital zoom so often present a pixelation effect ("noise").
In any case, if you want to buy your camera online, I suggest you go see
shop front. To go the fiddle, the weighing, the grind. See if the size is right for you, if you
well in hand, if the wheels are easy to access.

The race to the number of megapixels is not a selection criterion. From the moment you can print
no picture beyond 20x30 (A4), 6 megapixels is plenty.
