Olympus E-M10 IV vs Olympus E-M10 II: Physical Specs and Body features Comparison

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 Olympus E-M10 II 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). 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 Olympus E-M10 IV and Olympus E-M10 II. Olympus E-M10 II is clearly the smaller of the two cameras. Its body is 2mm narrower, 1mm shorter and 2mm thinner than Olympus E-M10 IV.

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 7g lighter than the Olympus E-M10 II 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 both Olympus E-M10 IV and Olympus E-M10 II 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.

Which camera has more lenses?

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. Olympus E-M10 IV and Olympus E-M10 II have the same Micro Four Thirds lens mount and currently there are 120 native lenses available for these cameras.

Another important factor is the availability of image stabilization.
