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

Fujifilm GFX 100 has a 3.2" Tilting screen with 2,360k dot resolution and Leica S2 has a 3.0" Fixed screen with 460k dot resolution. Tilting screen makes Fujifilm GFX 100 very useful for photography purposes but not so useful for video shooting. Fujifilm GFX 100 also features 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

Fujifilm GFX 100 has a built-in 0.5" Electronic (OLED) viewfinder with 5,760k dot resolution and Leica S2 has a built-in Optical (pentaprism) viewfinder. Fujifilm GFX 100 has 100% coverage with 0.68x (0.86x 35mm equivalent) magnification and Leica S2 has 96% coverage with 0.86x magnification.

Fujifilm GFX 100 features a 102 megapixel Medium format BSI-CMOS sensor with dimensions of 43.8 x 32.9 mm and a total area of 1441 mm². Its native ISO range is 100 - 12,800 and expands to 50 - 102,400 in boosted mode. Leica S2 features a 38 megapixel Medium format CCD sensor with dimensions of 45 x 30 mm and a total area of 900 mm². Its native ISO range is 80 - 1,250.

Fujifilm GFX 100 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.

Here is a sensor size comparison chart where you can see how different sensors compare with each other:

Fujifilm GFX 100 is equipped with X-Processor 4 processor and can take pictures up to 11648 x 8736 resolution. Leica S2 can take pictures up to 7500 x 5000 resolution.

Lens Mount

Fujifilm GFX 100 has Fujifilm G lens mount and Leica S2 has Leica S lens mount. Due to their Medium format sensor their crop factor (also called lens multiplier) 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 100

Fujifilm GFX 100 has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 5.5 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 on Fujifilm GFX 100

Fujifilm GFX 100 has a built-in Wi-Fi (Wi-Fi 5, 802.11ac/b/g/n, 2.4/5 GHz) 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.

Bluetooth on Fujifilm GFX 100

Fujifilm GFX 100 has a built-in Bluetooth (version 4.2 LE) which lets you to connect the camera to a smartphone or a dedicated remote control device. This allows you to remotely trigger the camera, adjust settings and controls remotely through a paired mobile app. While Wi-Fi is generally faster for transferring larger files, Bluetooth can be used for small, selective transfers, it can provide real-time information about your camera's battery status, memory card capacity, and other key settings directly on your paired smartphone or smartwatch.
