Canon M5 vs Olympus E-M1 III

Its time to look a bit more in depth at the Canon M5 and Olympus E-M1 III, one is a Advanced Mirrorless and the latter is a Pro Mirrorless by manufacturers Canon and Olympus. The image resolution of the M5 (24MP) and the E-M1 III (20MP) is relatively close but the M5 (APS-C) and E-M1 III (Four Thirds) feature totally different sensor sizing.

The M5 was manufactured 4 years earlier than the E-M1 III which is a fairly serious gap as far as camera tech is concerned. The two cameras come with the identical body type (SLR-style mirrorless).

Before going through a thorough comparison, below is a brief view of how the M5 grades versus the E-M1 III when considering portability, imaging, features and an overall score.

If you're aiming to carry around your camera often, you are going to need to factor its weight and dimensions. The Canon M5 provides outside measurements of 116mm x 89mm x 61mm (4.6" x 3.5" x 2.4") having a weight of 427 grams (0.94 lbs) whilst the Olympus E-M1 III has dimensions of 134mm x 91mm x 69mm (5.3" x 3.6" x 2.7") along with a weight of 580 grams (1.28 lbs).

Remember that, the weight of an Interchangeable Lens Camera will differ dependant on the lens you use at that moment. Below is the front view dimension comparison of the M5 vs the E-M1 III.

Looking at size and weight, the portability score of the M5 and E-M1 III is 77 and 67 respectively.

In many cases, it is very tough to visualise the gap in sensor sizes merely by looking through specs. The image below might provide you a far better sense of the sensor sizing in the M5 and E-M1 III.

All in all, both cameras have got different megapixel count and different sensor sizes. The M5 because of its bigger sensor will make shooting shallower depth of field less difficult and the Canon M5 will provide you with extra detail due to its extra 4 Megapixels. Higher resolution can also let you crop pictures much more aggressively. The more aged M5 will be behind in sensor innovation.
