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

Sony Alpha 6100 has a 3.0" screen with 922k dot resolution and Fujifilm GFX 100 II has a 3.2" screen with 2,360k dots resolution. Both have Tilting screens. Tilting screen makes cameras 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

Sony Alpha 6100 has a built-in 0.39" Electronic (OLED) viewfinder with 1,440k dot resolution and Fujifilm GFX 100 II has a built-in 0.64" Electronic (OLED) viewfinder with 9,440k dots resolution. They both have 100% coverage.

Sony Alpha 6100 features a 24.2 megapixel APS-C CMOS sensor with dimensions of 23.5 x 15.6 mm and a total area of 366.6 mm². Its native ISO range is 100 - 32,000 and expands to 100 - 51,200 in boosted mode. Fujifilm GFX 100 II 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 Still: 80 - 12,800
Movie: 100 - 12,800 and expands to Still: 40 - 102,800
Movie: 100 - 25,600 in boosted mode.

Fujifilm GFX 100 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.

Sony Alpha 6100 is equipped with BIONZ X processor and can take pictures up to 6000 x 4000 resolution. Fujifilm GFX 100 II is equipped with X-Processor 5 processor and can take pictures up to 11648 x 8736 resolution.

Lens Mount

Sony Alpha 6100 has Sony E lens mount and Fujifilm GFX 100 II has Fujifilm G lens mount. Due to APS-C sensor in Sony Alpha 6100 its crop factor is equal to 1.5x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5. Due to Medium Format sensor in Fujifilm GFX 100 II 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.

No Low-Pass Filter on Fujifilm GFX 100 II

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Fujifilm GFX 100 II. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization on Fujifilm GFX 100 II

Fujifilm GFX 100 II has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 8 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 Sony Alpha 6100, Wi-Fi 5 802.11ac/b/g/n 2.4/5 GHz on Fujifilm GFX 100 II) 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.
