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 L120 and Olympus E-M1 side-by-side from the front, back and top in their relative dimensions. Nikon L120 has external dimensions of 110 x 77 x 78 mm (4.33 x 3.03 x 3.07″) and weighs 431 g (0.95 lb / 15.20 oz) (including batteries). Olympus E-M1 has external dimensions of 130 x 94 x 63 mm (5.13 x 3.68 x 2.48″) and weighs 497 g (1.10 lb / 17.53 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L120 and the Olympus E-M1. Nikon L120 is 20mm narrower and 17mm shorter than Olympus E-M1 but it is also 15mm thicker. As you can tell, actually this is not a fair size comparison since Nikon L120 has a built-in lens but Olympus E-M1 doesn't. Once you put a lens on E-M1, its thickness will increase significantly.
Here is the back view size comparison of the Nikon L120 and Olympus E-M1.
Now lets look at the top view comparison of Nikon L120 and Olympus E-M1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L120 is 66g lighter than the Olympus E-M1 but we don't think this will make a significant difference.
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-M1, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the E-M1, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the L120.
LCD Screen Size and Features
Nikon L120 and Olympus E-M1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-M1 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 L120 has a fixed type screen which provides less flexibility in shooting positions compared to E-M1.
