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 D30 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 D30 has external dimensions of 109 x 68 x 28 mm (4.29 x 2.68 x 1.1″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G12 and the Canon D30. Canon D30 is clearly the smaller of the two cameras. Its body is 3mm narrower, 8mm shorter and 20mm thinner than Canon G12.
Here is the back view size comparison of the Canon G12 and Canon D30.
Now lets look at the top view comparison of Canon G12 and Canon D30.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon D30 is significantly lighter (183g ) than the Canon G12 which may become a big advantage especially on long walking trips.
Weather Sealing
Thanks to the weather-sealed body of the D30, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the G12.
LCD Screen Size and Features
Canon D30's 3.00" LCD screen is slightly larger than Canon G12's 2.8 screen.
On the other hand, Canon G12 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Canon D30 has a fixed type screen which provides almost no flexibility in shooting positions compared to G12.
