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 Panasonic Lumix DMC-GF1 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 Panasonic Lumix DMC-GF1 has a built-in Electronic (Optional) viewfinder. Fujifilm GFX 100 has 100% coverage with 0.68x (0.86x 35mm equivalent) magnification and 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. Panasonic Lumix DMC-GF1 features a 12 megapixel Micro Four Thirds CMOS sensor with dimensions of 17.3 x 13 mm and a total area of 169 mm². Its native ISO range is 100 - 3,200.

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.

Lens Mount

Fujifilm GFX 100 has Fujifilm G lens mount and Panasonic Lumix DMC-GF1 has Micro Four Thirds lens mount. Due to Medium format sensor in Fujifilm GFX 100 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. Due to Micro Four Thirds sensor in Panasonic Lumix DMC-GF1 its crop factor is equal to 2x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 2.

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.
