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 Olympus 8010 and Olympus E-M10 II side-by-side from the front, back and top in their relative dimensions. Olympus 8010 has external dimensions of 98 x 64 x 24 mm (3.86 x 2.52 x 0.94″) and weighs 245 g (0.54 lb / 8.64 oz) (including batteries). Olympus E-M10 II has external dimensions of 120 x 83 x 47 mm (4.72 x 3.27 x 1.85″) and weighs 390 g (0.86 lb / 13.76 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus 8010 and the Olympus E-M10 II. Olympus 8010 is clearly the smaller of the two cameras. Its body is 22mm narrower, 19mm shorter and 23mm thinner than Olympus E-M10 II. As you can tell, actually this is not a fair size comparison since Olympus 8010 has a built-in lens but Olympus E-M10 II doesn't. Once you put a lens on E-M10 II, its thickness will increase significantly.
Now lets look at the top view comparison of Olympus 8010 and Olympus E-M10 II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus 8010 is significantly lighter (145g ) than the Olympus E-M10 II 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 II, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the 8010, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the E-M10 II.
LCD Screen Size and Features
Olympus E-M10 II's 3.00" LCD screen is slightly larger than Olympus 8010's 2.7" screen.
In addition to the size advantage, Olympus E-M10 II LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Olympus 8010 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 II.
