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 Olympus SZ-30MR and Nikon P520 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). Nikon P520 has external dimensions of 125 x 84 x 102 mm (4.92 x 3.31 x 4.02″) and weighs 550 g (1.21 lb / 19.40 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SZ-30MR and the Nikon P520. Olympus SZ-30MR is clearly the smaller of the two cameras. Its body is 19mm narrower, 15mm shorter and 62mm thinner than Nikon P520.
Now lets look at the top view comparison of Olympus SZ-30MR and Nikon P520.
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 (324g ) than the Nikon P520 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Olympus SZ-30MR nor Nikon Coolpix P520 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
Nikon P520's 3.20" LCD screen is slightly larger than Olympus SZ-30MR's 3" screen.
Moreover, Nikon P520 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 SZ-30MR has a fixed type screen which provides almost no flexibility in shooting positions compared to P520.
