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.

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.
