Olympus E-M10 IV vs Olympus E-M10 III: 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 III 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 III has external dimensions of 122 x 84 x 50 mm (4.8 x 3.31 x 1.97″) and weighs 410 g (0.90 lb / 14.46 oz) (including batteries).

Below you can see the front view size comparison of Olympus E-M10 IV and Olympus E-M10 III. Olympus E-M10 IV has the same height and width with Olympus E-M10 III. On the other hand, with a thickness of 49mm, it is 1mm thinner.

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 27g lighter than the Olympus E-M10 III 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 III 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.

Sensor Size and Resolution Comparison image of Olympus E-M10 IV and Olympus E-M10 III Cameras


Olympus E-M10 IV and Olympus E-M10 III have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Olympus E-M10 III has 26% larger pixel area (14.20µm2 vs 11.22µm2) compared to Olympus E-M10 IV, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.

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 III 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. Both Olympus E-M10 IV and Olympus E-M10 III has Sensor based Image stabilization which means that all the lenses will be stabilized in these bodies.
