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 SX30 IS and Olympus SP-810 UZ 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 SP-810 UZ has external dimensions of 106 x 76 x 74 mm (4.17 x 2.99 x 2.91″) and weighs 413 g (0.91 lb / 14.57 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX30 IS and the Olympus SP-810 UZ. Olympus SP-810 UZ is clearly the smaller of the two cameras. Its body is 17mm narrower, 16mm shorter and 34mm 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 SP-810 UZ is significantly lighter (188g ) than the Canon SX30 IS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot SX30 IS nor Olympus SP-810 UZ 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
Olympus SP-810 UZ's 3.00" 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 SP-810 UZ has a fixed type screen which provides almost no flexibility in shooting positions compared to SX30 IS.
