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 SX30 IS and Olympus TG-810 side-by-side from the front, back and top in their relative dimensions. Canon SX30 IS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 601 g (1.32 lb / 21.20 oz) (including batteries). Olympus TG-810 has external dimensions of 100 x 65 x 26 mm (3.94 x 2.56 x 1.02″) and weighs 215 g (0.47 lb / 7.58 oz) (including batteries).
Below you can see the front view size comparison of Canon SX30 IS and Olympus TG-810. Olympus TG-810 is clearly the smaller of the two cameras. Its body is 23mm narrower, 27mm shorter and 82mm thinner than Canon SX30 IS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus TG-810 is significantly lighter (386g ) than the Canon SX30 IS which may become a big advantage especially on long walking trips.
LCD Screen Size and Features
Olympus TG-810's 3" LCD screen is slightly larger than Canon SX30 IS's 2.7" screen.
On the other hand, Canon SX30 IS 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, Olympus TG-810 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX30 IS.
