Olympus E-M10 IV vs Canon M100: 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 Canon M100 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).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Canon M100 is significantly lighter (81g ) than the Olympus E-M10 IV 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 Canon M100 has an APS-C sized sensor and Olympus E-M10 IV has a smaller Four Thirds sensor, Olympus E-M10 IV's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon M100 lenses.

Olympus E-M10 IV vs Canon M100 Comparison of Available Lenses
Which camera has more lenses?

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Olympus E-M10 IV has an advantage over Canon M100. There are 120 lenses for Olympus E-M10 IV's Micro Four Thirds mount, on the other hand there are only 29 lenses for Canon M100's Canon EF-M lens mount.

Another important factor is the availability of image stabilization. Olympus E-M10 IV has a big advantage in this regard because it has a sensor based image stabilization (IS) which means that all the lenses mounted to this body will be stabilized. E-M10 IV's built-in Image stabilization system is effective to compensate vibration up to 4.5-stops according to CIPA standards.
On the other hand, Canon M100 doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 6 lenses for Canon EF-M mount with Optical Image Stabilization features.
