Canon R100 vs Olympus E-M10 III

Here is a in-depth comparison of the Canon R100 and Olympus E-M10 III, both Entry-Level Mirrorless cameras by rivals Canon and Olympus. There is a significant difference among the image resolutions of the R100 (24MP) and E-M10 III (16MP) and the R100 (APS-C) and E-M10 III (Four Thirds) possess totally different sensor sizes.

Keep in mind, the weight of an Interchangeable Lens Camera will differ depending on the lens you have during that time. Below is the front view overall size comparison of the R100 against the E-M10 III.

Looking at size and weight, the portability grade of the R100 and E-M10 III is 76 and 80 respectively.

Generally, it is hard to envision the contrast in sensor sizing just by checking out technical specs. The graphic underneath should provide you a better sense of the sensor measurements in the R100 and E-M10 III.

As you have seen, the two cameras enjoy different megapixels and different sensor sizing. The R100 having a bigger sensor will make achieving shallower DOF easier and the Canon R100 will produce greater detail having an extra 8 Megapixels. Higher resolution will also help you crop photographs far more aggressively. The newer R100 is going to have an edge in sensor technology.
