Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Canon G12 and Canon N100 side-by-side from the front, back and top in their relative dimensions. Canon G12 has external dimensions of 112 x 76 x 48 mm (4.41 x 2.99 x 1.89″) and weighs 401 g (0.88 lb / 14.14 oz) (including batteries). Canon N100 has external dimensions of 105 x 68 x 36 mm (4.13 x 2.68 x 1.42″) and weighs 289 g (0.64 lb / 10.19 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G12 and the Canon N100. Canon N100 is clearly the smaller of the two cameras. Its body is 7mm narrower, 8mm shorter and 12mm thinner than Canon G12.
Here is the back view size comparison of the Canon G12 and Canon N100.
Now lets look at the top view comparison of Canon G12 and Canon N100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon N100 is significantly lighter (112g ) than the Canon G12 which may become a big advantage especially on long walking trips.
