Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon G12 and Fujifilm XQ1 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). Fujifilm XQ1 has external dimensions of 100 x 59 x 33 mm (3.94 x 2.32 x 1.3″) and weighs 206 g (0.45 lb / 7.27 oz) (including batteries).
Below you can see the front view size comparison of Canon G12 and Fujifilm XQ1. Fujifilm XQ1 is clearly the smaller of the two cameras. Its body is 12mm narrower, 17mm shorter and 15mm thinner than Canon G12.
Here is the back view size comparison of Canon G12 and Fujifilm XQ1.
Now lets look at the top view comparison of Canon G12 and Fujifilm XQ1.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm XQ1 is significantly lighter (195g ) than the Canon G12 which may become a big advantage especially on long walking trips.
Unfortunately neither Canon PowerShot G12 nor Fujifilm XQ1 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Fujifilm XQ1's 3" 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, Fujifilm XQ1 has a fixed type screen which provides almost no flexibility in shooting positions compared to G12.
