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 YI M1 and Sony A6500 side-by-side from the front, back and top in their relative dimensions. YI M1 has external dimensions of 114 x 64 x 34 mm (4.49 x 2.52 x 1.34″) and weighs 350 (including batteries). Sony A6500 has external dimensions of 120 x 67 x 53 mm (4.72 x 2.64 x 2.09″) and weighs 453 g (1.00 lb / 15.98 oz) (including batteries).
Below you can see the front view size comparison of YI M1 and Sony A6500. YI M1 is clearly the smaller of the two cameras. Its body is 6mm narrower, 3mm shorter and 19mm thinner than Sony A6500.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
YI M1 is 453g lighter than the Sony A6500 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Sony A6500 has an APS-C sized sensor and YI M1 has a smaller Four Thirds sensor, YI M1's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A6500 lenses.
Thanks to the weather sealed body of A6500, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to M1.
LCD Screen Size and Features
YI M1 and Sony A6500's LCD screens has the same diagonal size of 3".
On the other hand, Sony A6500 features a Tilting screen
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the YI M1 has a fixed type screen which provides less flexibility in shooting positions compared to A6500.
