In this section we present pros and cons of Fujifilm GFX 100S.

Tilting Touchscreen

Fujifilm GFX 100S has a 3.2" Tilting touchscreen with 2,360k dot resolution which is quite high by today's standards. Tilting screen makes this camera very useful for photography purposes but not so useful for video shooting.

Electronic (OLED) Viewfinder

Camera has a built-in 0.5" Electronic (OLED) viewfinder with 3,690k dot resolution. It has a 100% coverage and 0.61x (0.77x 35mm equivalent) magnification.

BSI-CMOS Sensor

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 1441 mm². Its native ISO range is 100 - 12,800 and expands to 50 - 102,400 in boosted mode.

The camera 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.

Camera is equipped with X-Processor 4 processor and can take pictures up to 11648 x 8736 resolution.

Lens Mount

Fujifilm GFX 100S has Fujifilm G lens mount. Due to Medium format sensor its crop factor (also called lens multiplier) is 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

The camera 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

Camera has a built-in Wi-Fi (802.11b/g/n, 2.4 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

Camera 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.
