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 B700 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 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).
Below you can see the front view size comparison of Olympus E-M10 IV and Nikon B700. Olympus E-M10 IV is clearly the smaller of the two cameras. Its body is 3mm narrower, 1mm shorter and 58mm thinner than Nikon B700. As you can tell, actually this is not a fair size comparison since Nikon B700 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 B700.
Now lets look at the top view comparison of Olympus E-M10 IV and Nikon B700.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus E-M10 IV is significantly lighter (182g ) 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-M10 IV, the total kit will weigh much higher.
Unfortunately neither Olympus OM-D E-M10 IV nor Nikon Coolpix B700 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
