We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

Screen

Canon EOS 6D Mark II and Sony Alpha 7C II have 3.0" Fully Articulated screens with 1,040k dot and 1,037k dots resolutions respectively. Fully articulated screen makes cameras selfie and vlogger friendly and generally very useful for video shooting. Both models feature touchscreen which has advantages such as easy menu navigation, intuitive controls, quick setting adjustment and most importantly a Touch-to-Focus functionality allowing users to select a specific point on the screen where they want the camera to focus. This feature can be helpful for achieving precise focus in both photo and video recording.

Viewfinder

Canon EOS 6D Mark II has a built-in Optical (pentaprism) viewfinderSony Alpha 7C II has a built-in 0.39" Electronic (OLED) viewfinder with 2,359k dots resolution. Canon EOS 6D Mark II has 98% coverage with 0.71x magnification and Sony Alpha 7C II has 100% coverage with 0.7x magnification.

Canon EOS 6D Mark II features a 26.2 megapixel Full Frame CMOS sensor with dimensions of 35.9 x 24 mm and a total area of 861.6 mm². Its native ISO range is 100 - 40,000 and expands to 50 - 102,400 in boosted mode. Sony Alpha 7C II features a 33.0 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.9 x 23.9 mm and a total area of 571.2 mm². Its native ISO range is 100 - 51,200 and expands to 50 - 204,800 in boosted mode.

Sony Alpha 7C II has BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

Canon EOS 6D Mark II is equipped with DIGIC 7 processor and can take pictures up to 6240 x 4160 resolution. Sony Alpha 7C II is equipped with Bionz XR processor and can take pictures up to 7008 x 4672 resolution.

Lens Mount

Canon EOS 6D Mark II has Canon EF lens mount and Sony Alpha 7C II has Sony E lens mount. Due to their Full Frame sensor their crop factor (also called lens multiplier) is equal to 1x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length.

In-Body Image Stabilization on Sony Alpha 7C II

Sony Alpha 7C II has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 7 stops of compensation. This means that you are still getting vibration reduction when camera is paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

Built-in GPS on Canon EOS 6D Mark II

Canon EOS 6D Mark II has a built-in GPS (Global Positioning System) technology which allows you to automatically tag the location where you took your photos. You can later categorize, organize, and search for photos based on location. This is very useful for travel and outdoor photographers for documenting the locations where images were captured.
