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 E-M1X and YI M1 side-by-side from the front, back and top in their relative dimensions. Olympus E-M1X has external dimensions of 144 x 147 x 75 mm (5.67 x 5.79 x 2.95″) and weighs 997 g (2.20 lb / 35.17 oz) (including batteries). YI M1 has external dimensions of 114 x 64 x 34 mm (4.49 x 2.52 x 1.34″) and weighs 350 g (including batteries).
Below you can see the front-view size comparison of the Olympus E-M1X and the YI M1. YI M1 is clearly the smaller of the two cameras. Its body is 30mm narrower, 83mm shorter and 41mm thinner than Olympus E-M1X.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
YI M1 is significantly lighter (647g ) than the Olympus E-M1X which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Olympus E-M1X and YI M1 have the same Micro Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
With its weather-sealed body, we believe that the E-M1X has a big advantage over the M1 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Olympus E-M1X and YI M1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-M1X sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. YI M1's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to E-M1X.
