Canon R3 vs Olympus E-M1 II

Below is a extensive review of the Canon R3 versus Olympus E-M1 II, both Pro Mirrorless digital cameras by rivals Canon and Olympus. The sensor resolution of the R3 (24MP) and the E-M1 II (20MP) is very well matched but the R3 (Full frame) and E-M1 II (Four Thirds) offer different sensor size.

The R3 was introduced 5 years later than the E-M1 II and that is quite a big difference as far as tech is concerned. Both cameras have the same body design (SLR-style mirrorless).

Before we go into a detailed comparison, here is a brief introduction of how the R3 matches up against the E-M1 II when it comes to portability, imaging, features and an overall grade.

This is a sample of the gallery pics for Canon EOS R3 & Olympus OM-D E-M1 Mark II. The whole galleries are available at Canon R3 Gallery & Olympus E-M1 II Gallery.

If you are looking to lug around your camera regularly, you're going to have to factor in its weight and dimensions. The Canon R3 provides external dimensions of 150mm x 143mm x 87mm (5.9" x 5.6" x 3.4") having a weight of 1015 grams (2.24 lbs) whilst the Olympus E-M1 II has dimensions of 134mm x 91mm x 67mm (5.3" x 3.6" x 2.6") with a weight of 574 grams (1.27 lbs).

Remember that, the weight of an ILC will vary dependant on the lens you are using at that moment. Following is a front view size comparison of the R3 vs the E-M1 II.

Looking at size and weight, the portability grade of the R3 and E-M1 II is 52 and 68 respectively.

Oftentimes, it's tough to visualize the difference between sensor measurements merely by checking a spec sheet. The photograph below might offer you a more clear sense of the sensor dimensions in the R3 and E-M1 II.

Clearly, both of the cameras provide different megapixels and different sensor measurements. The R3 having a larger sensor is going to make achieving shallow depth of field simpler and the Canon R3 will resolve more detail using its extra 4 Megapixels. Greater resolution will also enable you to crop images more aggressively. The more modern R3 should have an advantage in sensor tech.
