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 Olympus SZ-30MR and Canon G1 X side-by-side from the front, back and top in their relative dimensions. Olympus SZ-30MR has external dimensions of 106 x 69 x 40 mm (4.17 x 2.72 x 1.57″) and weighs 226 g (0.50 lb / 7.97 oz) (including batteries). Canon G1 X has external dimensions of 117 x 81 x 65 mm (4.61 x 3.19 x 2.56″) and weighs 534 g (1.18 lb / 18.84 oz) (including batteries).
Below you can see the front view size comparison of Olympus SZ-30MR and Canon G1 X. Olympus SZ-30MR is clearly the smaller of the two cameras. Its body is 11mm narrower, 12mm shorter and 25mm thinner than Canon G1 X.
Now lets look at the top view comparison of Olympus SZ-30MR and Canon G1 X.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus SZ-30MR is significantly lighter (308g ) than the Canon G1 X which may become a big advantage especially on long walking trips.
Unfortunately neither Olympus SZ-30MR nor Canon PowerShot G1 X provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Olympus SZ-30MR and Canon G1 X's LCD screens has the same diagonal size of 3".
On the other hand, Canon G1 X 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. Olympus SZ-30MR's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G1 X.
