Olympus E-M10 IV vs Olympus E-M1 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-M1 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-M1 III has external dimensions of 134 x 91 x 69 mm (5.28 x 3.58 x 2.72″) and weighs 580 g (1.28 lb / 20.46 oz) (including batteries).

Below you can see the front view size comparison of Olympus E-M10 IV and Olympus E-M1 III. Olympus E-M10 IV is clearly the smaller of the two cameras. Its body is 12mm narrower, 7mm shorter and 20mm thinner than Olympus E-M1 III.

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 significantly lighter (197g ) than the Olympus E-M1 III 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 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-M1 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.

Olympus E-M10 IV vs Olympus E-M1 III: Sensor Comparison

Both Olympus E-M10 IV and Olympus E-M1 III have Four Thirds sized 20.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.

One other difference between these two cameras that is worth mentioning is that Olympus E-M1 III's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

Below you can see the E-M10 IV and E-M1 III sensor size comparison.

Olympus E-M10 IV vs Olympus E-M1 III Comparison of Available Lenses
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-M1 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-M1 III has Sensor based Image stabilization which means that all the lenses will be stabilized in these bodies. E-M10 IV's built-in Image stabilization system is effective to compensate vibration up to 4.5-stops according to CIPA standards whereas E-M1 III's IS system is rated upto 7.0-stops.
