Canon R100 vs OM System OM-1

Let's look a little more in depth at the Canon R100 vs OM System OM-1, one is a Entry-Level Mirrorless and the other is a Pro Mirrorless by companies Canon and Olympus. The sensor resolution of the R100 (24MP) and the OM System OM-1 (20MP) is fairly close but the R100 (APS-C) and OM System OM-1 (Four Thirds) use totally different sensor dimensions.

The R100 was brought out 16 months after the OM System OM-1 making the cameras a generation away from each other. Each of these cameras offer the identical body type (SLR-style mirrorless).

Before delving in to a more detailed comparison, below is a simple summation of how the R100 scores versus the OM System OM-1 for portability, imaging, features and an overall score.

Below is a sample of the gallery pictures for Canon EOS R100 and OM System OM-1. The entire galleries are provided at Canon R100 Gallery and OM System OM-1 Gallery.

For those who are looking to carry around your camera, you will need to factor its weight and proportions.

Oftentimes, it can be hard to see the difference in sensor sizes purely by looking through a spec sheet. The image here may give you a more clear sense of the sensor dimensions in the R100 and OM System OM-1.

Clearly, the 2 cameras offer different megapixel count and different sensor sizes. The R100 because of its larger sensor will make getting shallower depth of field easier and the Canon R100 will result in greater detail having its extra 4MP. Greater resolution can also let you crop images a little more aggressively. The more recent R100 will have an advantage in sensor tech.
