Canon 77D vs Sony A77 II: Physical Specs and Body features Comparison

Size and weight is a big decision factor when you are trying to find the ideal camera for your needs. In this section, We are going to illustrate Canon 77D and Sony A77 II side-by-side from the front, back and top in their relative dimensions. Canon 77D has external dimensions of 131 x 100 x 76 mm (5.16 x 3.94 x 2.99″) and weighs 540 g (1.19 lb / 19.05 oz) (including batteries).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Canon 77D is significantly lighter (107g ) than the Sony A77 II which may become a big advantage especially on long walking trips.

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 both Canon 77D and Sony A77 II have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.

DxOMark Sensor Scores

DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Canon 77D and Sony A77 II sensors have been tested by DxO and the results show that A77 II has a better overall score of 82, 4 points higher compared to 77D's score of 78.

Model Overall Color Depth Dynamic Range Low-light ISO
Canon 77D 78 23.6 bits 13.3 Evs 971 ISO
Sony A77 II 82 24.4 bits 13.4 Evs 1013 ISO
Canon 77D vs Sony A77 II 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 Sony A77 II. There are 333 lenses for Canon 77D's Canon EF/EF-S mount, on the other hand there are only 143 lenses for Sony A77 II's Sony/Minolta Alpha lens mount.

Another important factor is the availability of image stabilization. Sony A77 II 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 113 lenses for Canon EF/EF-S mount with Optical Image Stabilization features.
