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 W300 and Olympus E-M10 III side-by-side from the front, back and top in their relative dimensions. Nikon W300 has external dimensions of 112 x 66 x 29 mm (4.41 x 2.6 x 1.14″) and weighs 231 g (0.51 lb / 8.15 oz) (including batteries). Olympus E-M10 III has external dimensions of 122 x 84 x 50 mm (4.8 x 3.31 x 1.97″) and weighs 410 g (0.90 lb / 14.46 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon W300 and the Olympus E-M10 III. Nikon W300 is clearly the smaller of the two cameras. Its body is 10mm narrower, 18mm shorter and 21mm thinner than Olympus E-M10 III. As you can tell, actually this is not a fair size comparison since Nikon W300 has a built-in lens but Olympus E-M10 III doesn't. Once you put a lens on E-M10 III, its thickness will increase significantly.
Here is the back view size comparison of the Nikon W300 and Olympus E-M10 III.
Now lets look at the top view comparison of Nikon W300 and Olympus E-M10 III.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon W300 is significantly lighter (179g ) than the Olympus E-M10 III 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-M10 III, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the W300, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the E-M10 III.
LCD Screen Size and Features
Nikon W300 and Olympus E-M10 III's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-M10 III features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Nikon W300 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 III.
