Canon 77D vs Olympus E-M1 Comparison Overview

Here we are comparing two cameras with different body types: Canon 77D is a Entry-Level DSLR camera with a 24.0MP APS-C sensor whereas Olympus E-M1 is a Pro Mirrorless camera with a 16.0MP Four Thirds sensor.
Despite some fundamental differences of these two body types, Mirrorless cameras are becoming serious altenatives to DSLR cameras thanks to their size/weight advantages and recent improvements in their focus speeds , which makes this comparison even more interesting.

Canon 77D vs Olympus E-M1 Detailed Size Comparison

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Olympus E-M1 is 43g lighter than the Canon 77D but we don't think this will make a significant difference.

Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Canon 77D has an APS-C sized sensor and Olympus E-M1 has a smaller Four Thirds sensor, Olympus E-M1's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon 77D lenses.

Canon 77D vs Olympus E-M1: Sensor Comparison

Canon 77D has a 24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Olympus E-M1 has a 16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features TruePIC VII processor.

Canon 77D's sensor provides 8MP more than Olympus E-M1's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely. On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.

Below you can see the 77D and E-M1 sensor size comparison.

Canon 77D vs Olympus E-M1 Sensor Size Comparison


As seen above, Canon 77D has a 1.5x Larger sensor area than Olympus E-M1. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.

Olympus E-M1 vs Canon 77D Comparison of Available Lenses
Which camera has more lenses?

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Canon 77D has an advantage over Olympus E-M1. There are 299 lenses for Canon 77D's Canon EF/EF-S mount, on the other hand there are only 92 lenses for Olympus E-M1's Micro Four Thirds lens mount.

Another important factor is the availability of image stabilization. Olympus E-M1 has a big advantage in this regard because it has a sensor based image stabilization which means that all the lenses mounted to this body will be stabilized. On the other hand, Canon 77D doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 91 lenses for Canon EF/EF-S mount with Optical Image Stabilization features.
