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 E-M10 IV and Nikon AW130 side-by-side from the front, back and top in their relative dimensions. Olympus E-M10 IV has external dimensions of 122 x 84 x 49 mm (4.8 x 3.31 x 1.93″) and weighs 383 g (0.84 lb / 13.51 oz) (including batteries). Nikon AW130 has external dimensions of 110 x 66 x 27 mm (4.33 x 2.6 x 1.06″) and weighs 221 g (0.49 lb / 7.80 oz) (including batteries).
Below you can see the front view size comparison of Olympus E-M10 IV and Nikon AW130. Nikon AW130 is clearly the smaller of the two cameras. Its body is 12mm narrower, 18mm shorter and 22mm thinner than Olympus E-M10 IV. As you can tell, actually this is not a fair size comparison since Nikon AW130 has a built-in lens but Olympus E-M10 IV doesn't. Once you put a lens on E-M10 IV, its thickness will increase significantly.
Here is the back view size comparison of Olympus E-M10 IV and Nikon AW130.
Now lets look at the top view comparison of Olympus E-M10 IV and Nikon AW130.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon AW130 is significantly lighter (162g ) than the Olympus E-M10 IV 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 IV, the total kit will weigh much higher.
Thanks to the weather sealed body of AW130, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to E-M10 IV.
LCD Screen Size and Features
Olympus E-M10 IV and Nikon AW130's LCD screens has the same diagonal size of 3.00".
On the other hand, Olympus E-M10 IV 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 AW130 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 IV.
