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 SX120 IS and Canon G1 X II side-by-side from the front, back and top in their relative dimensions. Canon SX120 IS has external dimensions of 111 x 71 x 45 mm (4.37 x 2.8 x 1.77″) and weighs 285 g (0.63 lb / 10.05 oz) (including batteries). Canon G1 X II has external dimensions of 116 x 74 x 66 mm (4.57 x 2.91 x 2.6″) and weighs 553 g (1.22 lb / 19.51 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX120 IS and the Canon G1 X II. Canon SX120 IS is clearly the smaller of the two cameras. Its body is 5mm narrower, 3mm shorter and 21mm thinner than Canon G1 X II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX120 IS is significantly lighter (268g ) than the Canon G1 X II which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot SX120 IS nor Canon PowerShot G1 X Mark II 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 SX120 IS and Canon G1 X II's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon G1 X II features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon SX120 IS has a fixed type screen which provides less flexibility in shooting positions compared to G1 X MII.
