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 B700 and Olympus E-M5 III side-by-side from the front, back and top in their relative dimensions. Nikon B700 has external dimensions of 125 x 85 x 107 mm (4.92 x 3.35 x 4.21″) and weighs 565 g (1.25 lb / 19.93 oz) (including batteries). Olympus E-M5 III has external dimensions of 125 x 85 x 50 mm (4.92 x 3.35 x 1.97″) and weighs 414 g (0.91 lb / 14.60 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon B700 and the Olympus E-M5 III. Nikon B700 has the same height and width with Olympus E-M5 III. On the other hand, with a thickness of 107mm, it is 57mm thicker. As you can tell, actually this is not a fair size comparison since Nikon B700 has a built-in lens but Olympus E-M5 III doesn't. Once you put a lens on E-M5 Mark III, its thickness will increase significantly.
Here is the back view size comparison of the Nikon B700 and Olympus E-M5 III.
Now lets look at the top view comparison of Nikon B700 and Olympus E-M5 III.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-M5 III is significantly lighter (151g ) than the Nikon B700 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-M5 Mark III, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the E-M5 Mark III, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the B700.
