FUJIFILM has packed some of the world’s most advanced imaging technology inside a weather-sealed, portable body. The result is a camera that goes as far as you do to get the shot, from the studio to the Sierras.

Body & Build

Despite featuring a sensor which is 1.7 times larger than a 35mm full frame sensor, the GFX 100’s body is equivalent to that of a flagship 35mm full frame DSLR camera in terms of dimensions (156.2mm (W) x 163.6mm (H) x 102.9mm (D), measuring 48.9mm at the thinnest part) and weight (approx. 1400g including two batteries, memory card and EVF).

The camera body is made of magnesium alloy, making it lightweight and very robust. The inner frame directly couples the sensor and IBIS unit with lens and lens mount to provide complete rigidity from the lens to the sensor. The engagement area between the front and rear panels has been maximized to achieve ultimate durability against external force.

The camera body is weather sealed at 95 points (including the electronic viewfinder) helping it withstand extreme conditions of dust, moisture and low temperatures. This means that the camera can comfortably handle a wide variety of shooting situations, be it shooting stills or video. This means the GFX 100 is perfectly suited to being used in a studio but also outdoors in harsher environments.

The GFX 100 camera body has a built in vertical grip, it is the first FUJIFILM camera to have this integrated design. This allows the camera to be thinner and lighter than before while still housing a large sensor, shutter mechanism, IBIS and two batteries. This balanced design of the camera allows the user to instantly switch from landscape to portrait orientation.

Sensor / Processor / Mount

The new sensor, specifically developed for this camera, measures 55mm diagonally and boasts an effective pixel count of approx. 102 million. When combined with the fourth generation “X-Processor 4” processor, it delivers the world’s highest level of image quality with exceptional colour reproduction unique to FUJIFILM and the ultra sharp “FUJINON GF lenses.”

55mm diagonal length large format

The GFX Series' use of 55mm diagonal length large format (43.8 x 32.9mm) has paved the way for ultra high image resolution. The GFX 100 delivers smooth gradation and image sharpness with the high resolution sensor. This is made possible thanks to FUJIFILM's expertise in medium format which has been gained since the days of film cameras. Experience the astonishing photographic potential possible with the 100MP+ sensor.

The GFX 100 uses the X-Processor 4, FUJIFILM's latest image processing engine to quickly optimize the data from the fast, high resolution image sensor. Despite the massive amount of data involved, the processor handles it at a speed. You can also apply the Film Simulation modes to 100MP+ image data to achieve FUJIFILM's unique styles of colour and tone reproduction.

FUJIFILM G Mount

The G Mount, was designed to accommodate GF lenses with 100MP+ sensors in mind. Taking maximum advantage of the mirrorless system, the G Mount has a short flange focal distance which contributes to the camera's compact form and mirrors GF lenses' design and advanced performance. When combined with a large CMOS sensor, the system prevents peripheral light fall-off to achieve stunning edge to edge sharpness.

Stabilization

Generally speaking, the higher the pixel count an image sensor has, the higher the likelihood of camera shake. To avoid this threat to image quality, FUJIFILM has designed an IBIS system specifically for the new 102MP 55mm diagonal length large format which gives up to 5.5 stops* of image stabilization.

The GFX focal plane shutter is specifically designed for 55mm large format, mirrorless digital cameras. With a durability performance over 150,000 shutter actuations*, it combines an electronic front curtain shutter with an exceptionally quiet mechanical shutter which has a maximum speed of up to 1/4000sec. The shutter system has been redesigned for the GFX 100 to support the new 55mm diagonal length large format with continuous shooting of up to 5.0fps. You can select from three types of shutters, including an electronic shutter, according to your shooting conditions.
The GFX 100 is a first mirrorless digital camera equipped with an in-body image stabilization (IBIS) mechanism for a 55mm diagonal length large format in GFX series. It provides precision control for the high definition images produced by the camera's 55mm diagonal length large format, which is approx. 1.7 times the size of a 35mm format sensor. This feature revolutionizes the 55mm large format camera system, unleashing its advanced performance with greater flexibility in a wider variety of shooting conditions.

Finder / Monitor
The GFX 100 inherits GFX 50S’s popular detachable EVF system that can be adjusted to various angles when using the EVF Tilting Adapter EVF-TL1. The world’s highest class resolution 5.76 million dot OEL panel has been used to develop the GFX 100 high definition EVF unit. The viewfinder has a magnification of 0.86x and contains five optical glass elements including aspherical elements and has been specifically designed for the 102MP sensor, which requires extreme focusing accuracy.

The GFX 100 comes with a detachable 5.76M dot EVF with approx. 100% coverage. Resolution priority, frame rate priority and AF priority can be selected in boost mode for live view depending on the subject.

Attach the optional EVF Tilting Adapter EVF-TL1 between the camera body and the EVF will enable vertical tilt (0°-90° / 5 steps) and horizontal rotation (±45°). This allows you to shoot from waist level or aids shooting in portrait orientation.

The rear panel features a sub monitor, which can be configured to display various data previously displayed on the main LCD monitor. Minimizing the amount of data that has to be displayed on the main LCD monitor makes it easy to check the overall framing and concentrate on the composition. You can choose to display the exposure compensation gauge and histogram on the sub monitor to enable exposure adjustment whilst checking the exposure level.

The top panel features a clear, 1.8-inch B/W sub LCD monitor that displays the main shooting settings such as shutter speed, aperture, ISO sensitivity and exposure compensation, as well as function icons, remaining number of frames (stills) and remaining filming time (video). This display can be configured according to what information you want to be displayed. When you switch between stills and video modes, all the settings shown on this sub monitor also change accordingly, ensuring that all relevant data is available at hand.

Colours / Image setting

The combination of the newly developed image sensor and the fourth generation “X-Processor 4” processing engine means the camera also supports “16-bit RAW” mode, requested by many professional photographers. The GFX 100 also supports 16-bit TIFF in camera file conversion. The ultra high 100MP+ resolution and rich colour and tonal reproduction found in our FILM SIMULATION modes, significantly boosts photo data’s post processing tolerance, meeting the diverse needs of professional photographers.

Fujifilm's Original Colour Reproduction

As a manufacturer of cameras and photographic films for many years, Fujifilm has developed the Film Simulation modes to digitally replicate the image quality of film. The GFX 100 allows users reproduce these colours and tones, despite its large image resolution, adding an artistic flair to images with exceptional quality.

Movie recording

The combination of the new image sensor with high speed readout and the high performance fourth generation “X-Processor 4” engine has given the camera the ability to record 4K30p video (10bit 4:2:2 externally and 10bit 4:2:0 internally), a world’s first amongst Large Format.

4K Movie / 10bit Colour Depth

The full potential of the 55mm diagonal length large format in the GFX can be seen in stills and in video. The combination of the latest sensor and the "X-Processor 4" enables support for 4K/30P video. The camera's sensor, which is larger than that of cinema cameras, produces a shallow depth-of-field, enhanced tonal gradient in 10-bit output, and greater ISO sensitivity. The 55mm large format size produces video footage with more detailed textures while reproducing three-dimensional definitions and is able to capture the atmosphere of the scene unlike anything before. All the Film Simulation modes can be applied to video as well, including "Eterna," which replicates the look of FUJIFILM's cinema film of the same name. Furthermore, the camera supports the digital cinema aspect ratio (17:9) and compression codecs such as H.265 and H.264. You can also select the bit rate of up to 400Mbps.

Movie recording format

With its 55mm diagonal length large format, the GFX 100 demonstrates its appeal in video recording. It uses full sensor width to record video in 4K digital cinema format in the aspect ratios of 16:9 / 17:9. The sensor area used is greater than that of cinema cameras that support a large format sensor. You can use GF lenses and adaptors to achieve a variety of videographic expressions that only large sensors can deliver, and record them in high-resolution 4K video.

Simultaneous Output to HDMI and SD card

The high speed image processing engine, X-Processor 4, can read and output condensed video data, feeding 4K/30P 4:2:2 10bit data to the HDMI port and recording 4K/30P 4:2:0 10bit data to an SD card (when H.265 is selected) up to 400Mbps***. You can also choose All-Intra*4 / Long-GOP, etc. The processor's enhanced capability means video footage can be viewed on the camera's LCD screen as well as on an external monitor whilst you film, while feeding uncompressed data straight to a recorder.

F-Log / HLG Support

The GFX 100 is capable of recording F-Log, characterized by a gamma curve with a wide dynamic range, and capturing video in HLG (Hybrid Log Gamma), one of the formats defined in the ITU-R BT.2100 international standards. Coupled with colour information attained in 10-bit colour depth, the camera records premium quality footage faithfully depicting scenes even with a large brightness range or subjects with high colour saturation.

Focusing / Continuous shooting

The GFX 100 is the first model in the GFX System that uses our phase detection AF algorithm, adopted from the fourth generation X Series cameras (X-T3 and X-T30), and which is praised for its precision and speed. The algorithm makes full use of 3.76 million phase detection pixels, placed across the entire sensor, to set a new standard in AF speed and precision for Large Format performing the standard “Single Point” AF as well as “Zone” and “Wide Tracking” AF. The effect is particularly noticeable when using prime lenses with a heavy set of focus lens elements, achieving speed improvement of up to 210% over the conventional contrast AF system.

Phase Detection AF System

The GFX 100 is the first GFX that features a phase detection AF system on 55mm diagonal length large format. The GFX 100 has phase detection pixels across the entire sensor and with the X-Processor 4 engine coupled with the latest AF algorithm, is able to focus on a subject at high speed with accuracy even when the subject is away from the center of the frame, even in low light.

Six AF Modes and AF-C Customization

The GFX 100 has six AF modes that cater for all types of subject movement. The AF-S locks focus while the AF-C focuses continuously on a moving subject. These can be combined with focus area options, namely "Single Point," "Zone" and "Wide / Tracking." You can also keep six custom settings for AF-C to adjust “Tracking Sensitivity”, “Speed Tracking Sensitivity” and “Zone Area Switching” according to the characteristics of subject movement.

Leaf Spring Switch Shutter

The GFX 100 is equipped with a feather touch shutter button that responds to delicate shutter release actions. The button reacts to the subtlest movements of the finger when gripping the camera body firmly in both portrait and landscape orientations. The use of the electronic front-curtain shutter minimizes release time lag to give even greater confidence in shutter operation.

Face/Eye Tracking and Auto Focus

Using the new sensor in conjunction with the X-Processor 4, gives an advanced level of face tracking performance. The photographer has the ability to identify and capture even easier than before, difficult subjects like a person inside profile. In the Eye AF mode, you can even specify which of the subject's eyes you want the camera to prioritize. This is particularly useful in portraiture, which commands focusing accuracy with a very shallow depth of field. The touchscreen panel or Focus Lever can be used to select which of a crowd of faces detected you want the camera to track, focus and adjust exposure to.

Burst Mode

Continuous shooting is available in two frame rates, i.e. high speed burst at 5.0fps (CH) and low speed burst at 2.0fps, which can be checked in Live View. When the AF-C is selected, the GFX 100 combines it with various phase detection AF modes and face detection to shoot in bursts while tracking and focusing on a moving subject.

Various functions

The GFX 100 can accommodate two NP-T125 batteries, extending the number of frames per charge to approx. 800 when the rear LCD is used. The camera can also be powered and charged through the USB-C connection. Connecting an external battery that supports USB Power Delivery enables even longer continuous shooting and simultaneous charging of the two batteries in the camera.

Switch P / S / A / M Mode

The shooting mode button (Fn2) on the top panel allows you to switch between "Program (P)" and "Shutter Speed Priority (S)" (when the aperture is set to Auto) and between "Aperture Priority (A)" and "Manual (M)" (when the aperture is set to Manual). These selections can be assigned to a function button of your choice in Function (Fn) Setting.

Still / Multi / Movie mode switch

Rotate the Drive Mode Dial to switch between the Still, Multi and Movie modes. Selecting the Still or Movie mode restores the respective settings so that you can start shooting as soon as you switch, without having to adjust settings. The Drive Button allows you to adjust burst speed and video frame rate. The Dial Lock Release Button prevents any accidental use.

Buttons / Menu Customization

Numerous function (Fn) buttons are provided at various points on the camera body allowing you to assign your preferred settings for easy access. The 16 items shown in the Q (Quick) menu and C1 - C7 can also be reconfigured to instantly access your favorite Film Simulation modes or image quality settings. The camera also supports "My Menu," where your most frequently-used items can be stored.

Accessories / Workflow

Similarly to previous GFX models, the GFX 100 is compatible with “Tether Shooting Plug-in PRO for Adobe® Photoshop® L ghtroom®” and “Capture One Pro FUJIFILM” for RAW processing and tethered shooting to accommodate the workflow of any professional photographers.

Interface for External Connections

The GFX 100’s terminal for external connections features a USB-C port for high speed image transfer, a micro-HDMI port to connect to an external monitor, a microphone input, a headphone jack and a remote shutter release connection. The camera can be powered and charged by connecting an AC power adapter (optional) to the power plug input connector or a USB Power Delivery device to the USB-C port. The camera comes with a cable protector for holding cables in place.
