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 Casio EX-Z16 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). Casio EX-Z16 has external dimensions of 101 x 59 x 20 mm (3.98 x 2.32 x 0.79″) and weighs (including batteries).
Below you can see the front-view size comparison of the Canon G12 and the Casio EX-Z16. Casio EX-Z16 is clearly the smaller of the two cameras. Its body is 11mm narrower, 17mm shorter and 28mm thinner than Canon G12.
Here is the back view size comparison of the Canon G12 and Casio EX-Z16.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Casio EX-Z16 is 401g lighter than the Canon G12 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot G12 nor Casio Exilim EX-Z16 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G12's 2.80" LCD screen is slightly larger than Casio EX-Z16's screen.
Moreover, 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, Casio EX-Z16 has a fixed type screen which provides almost no flexibility in shooting positions compared to G12.
