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 SP-610UZ and Nikon P7800 side-by-side from the front, back and top in their relative dimensions. Olympus SP-610UZ has external dimensions of 107 x 73 x 73 mm (4.21 x 2.87 x 2.87″) and weighs 405 g (0.89 lb / 14.29 oz) (including batteries). Nikon P7800 has external dimensions of 119 x 78 x 50 mm (4.69 x 3.07 x 1.97″) and weighs 399 g (0.88 lb / 14.07 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SP-610UZ and the Nikon P7800. Olympus SP-610UZ is 12mm narrower and 5mm shorter than Nikon P7800 but it is also 23mm thicker.
Here is the back view size comparison of the Olympus SP-610UZ and Nikon P7800.
Now lets look at the top view comparison of Olympus SP-610UZ and Nikon P7800.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P7800 is 6g lighter than the Olympus SP-610UZ but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus SP-610UZ nor Nikon Coolpix P7800 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-610UZ and Nikon P7800's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon P7800 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 SP-610UZ's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P7800.
