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 Nikon P7700 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).

Now lets look at the top view comparison of Olympus SZ-30MR and Nikon P7700.
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 (166g ) than the Nikon P7700 which may become a big advantage especially on long walking trips.
Unfortunately neither Olympus SZ-30MR nor Nikon Coolpix P7700 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 Nikon P7700's LCD screens has the same diagonal size of 3".
On the other hand, Nikon P7700 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 P7700.
