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 Nikon S800c and Olympus E-PL6 side-by-side from the front, back and top in their relative dimensions. Nikon S800c has external dimensions of 111 x 60 x 27 mm (4.37 x 2.36 x 1.06″) and weighs 184 g (0.41 lb / 6.49 oz) (including batteries). Olympus E-PL6 has external dimensions of 111 x 64 x 38 mm (4.37 x 2.52 x 1.5″) and weighs 325 g (0.72 lb / 11.46 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S800c and the Olympus E-PL6. Nikon S800c has the same height with Olympus E-PL6. On the other hand, with a width of 60mm, it is 4 narrower and also with a thickness of 27mm, it is 11mm thinner than Olympus E-PL6. As you can tell, actually this is not a fair size comparison since Nikon S800c has a built-in lens but Olympus E-PL6 doesn't. Once you put a lens on E-PL6, its thickness will increase significantly.
Here is the back view size comparison of the Nikon S800c and Olympus E-PL6.
Now lets look at the top view comparison of Nikon S800c and Olympus E-PL6.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S800c is significantly lighter (141g ) than the Olympus E-PL6 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on E-PL6, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Nikon Coolpix S800c nor Olympus PEN E-PL6 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
