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 70D has a 3.0" Fully Articulated screen with 1,040k dot resolution and Fujifilm GFX 100S has a 3.2" Tilting screen with 2,360k dot resolution. Fully articulated screen makes Canon EOS 70D selfie and vlogger friendly and generally very useful for video shooting. Tilting screen makes Fujifilm GFX 100S very useful for photography purposes but not so 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 70D has a built-in Optical (pentaprism) viewfinderFujifilm GFX 100S has a built-in 0.5" Electronic (OLED) viewfinder with 3,690k dot resolution. Canon EOS 70D has 98% coverage with 0.95x (0.59x 35mm equivalent) magnification and Fujifilm GFX 100S has 100% coverage with 0.61x (0.77x 35mm equivalent) magnification.

Canon EOS 70D features a 20.2 megapixel APS-C CMOS sensor with dimensions of 22.5 x 15 mm and a total area of 337.5 mm². Its native ISO range is 100 - 12,800 and expands to 100 - 25,600 in boosted mode. Fujifilm GFX 100S features a 102 megapixel Medium format BSI-CMOS sensor with dimensions of 43.8 x 32.9 mm and a total area of 1082.4 mm². Its native ISO range is 100 - 12,800 and expands to 50 - 102,400 in boosted mode.

Fujifilm GFX 100S 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 70D is equipped with DIGIC 5+ processor and can take pictures up to 5472 x 3648 resolution. It can also take pictures with lower resolution like 3468x2432, 2736x1824, 1920x1280, 720x480, 4864x3648, 3248x2432, 2432x1824, 1696x1280, 640x480,5472x3072, 3468x2048, 2736x1536, 1920x1080, 720x408, 3648x3648, 2432x2432, 1824x1824, 1280x1280, 480x480 with 1:1, 4:3, 3:2, 16:9 aspect ratios. Fujifilm GFX 100S is equipped with X-Processor 4 processor and can take pictures up to 11648 x 8736 resolution.

Lens Mount

Canon EOS 70D has Canon EF/EF-S lens mount and Fujifilm GFX 100S has Fujifilm G lens mount. Due to APS-C sensor in Canon EOS 70D its crop factor is equal to 1.6x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.6. Due to Medium format sensor in Fujifilm GFX 100S its crop factor is equal to 0.79x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 0.79.

In-Body Image Stabilization on Fujifilm GFX 100S

Fujifilm GFX 100S has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 6 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 Wi-Fi

Cameras have built-in Wi-Fi (802.11b/g/n 2.4 GHz on Fujifilm GFX 100S) which allows to easily transfer photos and videos from the camera to other Wi-Fi-enabled devices, such as smartphones, tablets, printers, or computers. This eliminates the need for cables and allows for quick and convenient media sharing and social media integration. It gives you the ability to control your camera remotely using a smartphone or tablet. This is particularly useful for taking self-portraits, group shots, or capturing images in challenging conditions without having to touch the camera. Firmware updates can also be downloaded and installed wirelessly.
