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 P1000 and Olympus E-M5 II side-by-side from the front, back and top in their relative dimensions. Nikon P1000 has external dimensions of 146 x 119 x 181 mm (5.75 x 4.69 x 7.13″) and weighs 1415 g (3.12 lb / 49.91 oz) (including batteries). Olympus E-M5 II has external dimensions of 124 x 85 x 45 mm (4.88 x 3.35 x 1.77″) and weighs 469 g (1.03 lb / 16.54 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon P1000 and the Olympus E-M5 II. Olympus E-M5 II is clearly the smaller of the two cameras. Its body is 22mm narrower, 34mm shorter and 136mm thinner than Nikon P1000. As you can tell, actually this is not a fair size comparison since Nikon P1000 has a built-in lens but Olympus E-M5 II doesn't. Once you put a lens on E-M5 Mark II, its thickness will increase significantly.
Here is the back view size comparison of the Nikon P1000 and Olympus E-M5 II.
Now lets look at the top view comparison of Nikon P1000 and Olympus E-M5 II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-M5 II is significantly lighter (946g ) than the Nikon P1000 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 II, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the E-M5 Mark II, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the P1000.
