The 5D was announced 15 years earlier than the E-M1 III and that is a fairly sizable gap as far as camera tech is concerned. The two cameras offer different body type with the Canon 5D being a Mid-size SLR camera and the Olympus E-M1 III being a SLR-style mirrorless camera.

Before getting through a thorough comparison, below is a quick introduction of how the 5D matches up vs the E-M1 III in the way of portability, imaging, features and an overall rating.

Following is a preview of the gallery images for Canon EOS 5D and Olympus OM-D E-M1 Mark III. The whole galleries are viewable at Canon 5D Gallery and Olympus E-M1 III Gallery.

If you're looking to carry your camera frequently, you should factor in its weight and proportions. The Canon 5D enjoys outer measurements of 152mm x 113mm x 75mm (6.0" x 4.4" x 3.0") and a weight of 895 grams (1.97 lbs) and the Olympus E-M1 III has measurements of 134mm x 91mm x 69mm (5.3" x 3.6" x 2.7") with a weight of 580 grams (1.28 lbs).

In many cases, it can be difficult to visualize the contrast in sensor sizing merely by going through technical specs. The photograph underneath may provide you a stronger sense of the sensor sizing in the 5D and E-M1 III.

As you have seen, the 2 cameras offer different resolutions and different sensor sizing. The 5D using its bigger sensor is going to make getting bokeh simpler and the Olympus E-M1 III will provide more detail with its extra 7MP. Higher resolution will also allow you to crop photographs a little more aggressively. The older 5D will be disadvantaged with regard to sensor technology.
