Fujifilm Goes Big with Medium Format the Mirrorless FUJIFILM GFX100

FUJIFILM Corporation announced today the release of the FUJIFILM GFX100 mirrorless digital camera (“GFX100”) available in late June 2019, incorporating an image sensor with the world’s highest* 102 million pixels resolution and unique color reproduction technology.
The GFX100 is a flagship model of the GFX Series of mirrorless digital cameras, which have won strong praise from professional photographers and photo enthusiasts alike for the use of a large image sensor, boasting approximately 1.7 times the size of the 35mm full-frame sensor. Among digital cameras equipped with a sensor larger than the 35mm full-frame format, this is the world’s first** model that offers (1) a back-illuminated sensor with phase detection pixels, (2) in-body image stabilization (IBIS) mechanism and (3) 4K/30P video recording capability. The innovative mirrorless digital camera fulfills photography’s intrinsic mission of “capturing and recording precious moments that are never to be repeated again.”

The world’s highest 102 million pixels resolution delivers the world-leading image quality
With the features of the GFX series image sensor which has a diagonal length of about 55 mm (43.8 mm x 32.9 mm) and is approx. 1.7 times bigger than a 35 mm full-frame format, GFX100 has double the number of pixels compared to the current model***. Combining with the unique color reproduction technology, it achieves the world-leading image quality.

The GFX100 supports 4K/30P video recording, capturing smooth motions at 30fps in ultra-high-definition 4K video. The camera allows users to enjoy beautiful bokeh with shallow depth-of-field and wide tonal reproducibility, enabling premium video production while reproducing detailed textures, three-dimensional definitions and even capturing the atmosphere of the scene.

Carrying a newly-developed 102 million pixels image sensor to reach the world-leading image quality
The GFX100 carries the large format sensor, a newly-developed large image sensor with 102 million pixels resolution. It produces the world-leading photographic image quality when combined with the latest fourth-generation “X-Processor 4” high-speed image processing engine, ultra-sharp FUJINON GF lenses and color reproduction technology nurtured through the photographic film business over many years.

The image sensor has a back-illuminated structure with excellent light-receiving performance. The sensor takes advantage of its wide dynamic range to achieve rich tonal reproduction and low noise, while also achieving high-speed readout of image data despite the massive pixel count.
(2) Fast and high-precision phase detection AF

The GFX100 boasts highly accurate AF with exceptional ability to track a moving subject at a speed up to twice that of current models. This equates to the level of mobility that sets a new standard for digital cameras using an image sensor larger than the 35mm full-frame format.

As many as 3.78 million phase detection pixels are placed across the image sensor (approx. 100% coverage), quickly focusing on the subject regardless of where the subject is within the frame. Furthermore, the GFX Series adopts the latest phase detection AF algorithm, already popular with FUJIFILM X-T3 and FUJIFILM X-T30 in the X Series of Fujifilm’s mirrorless digital cameras, to achieve high-speed and high-precision AF in the “Single Point” as well as “Zone” and “Wide Tracking” of focus area.

The GFX100 boasts dramatic improvement in the accuracy of Face and Eye Detection AF, which has become an essential function in fashion photography and portrait photography. The Face Detection now works with a greater shooting distance and shows amazing tracking performance even for the side profile of a person or a subject that is partially blocked by an obstacle.

Powerful support for hand-held shooting with 5.5-stop five-axis in-body image stabilization
The GFX100 is equipped with a five-axis IBIS mechanism that delivers image stabilization of up to 5.5 stops.

Taking advantage of its sensor-shift structure, the IBIS stabilizes images not only against pitch and yaw movements (up / down and right / left tilting) but also against shift (vertical / horizontal) and roll (rotational) movements. The GFX100 is a first mirrorless digital camera equipped with an in-body image stabilization (IBIS) mechanism for a large format sensor in GFX series. It provides precision control for the high definition images produced by the camera’s large format sensor, which is approx. 1.7 times the size of a 35mm format sensor. This feature revolutionizes the large format camera system, unleashing its advanced performance with greater flexibility in a wider variety of shooting conditions.
Specification: three-axis accelerometer, three-axis gyro sensor, dedicated dual processor
Image stabilizer mechanism: Image sensor shift mechanism with 5-axis compensation
Compensation Effect: 5.5 stops *4

The entire shutter unit is suspended with four springs to minimize the effect of shutter shock. This dramatically broadens the scope of situations where users can hand-hold the camera and still enjoy the world of ultra-high 102 million pixels resolution.

4K/30P video recording capability to meet the needs of premium video production
The combination of the new image sensor with high-speed readout and the high-performance “X-Processor 4” image-processing engine has given the camera a capability of capturing smooth motions at 30fps in 4K video*5.

When the DCI (aspect ratio of 17:9), a standard format for digital cinema cameras, is selected, the GFX100 records video with a sensor area measuring about 49.5mm diagonally*6. The size, bigger than that of large sensors increasingly adopted by high-end cinema cameras*7, results in outstanding high ISO performance, shallow depth-of-field capability, and wide tonal reproducibility.

This makes it easier than ever before to produce premium-quality video footage with more detailed textures and three-dimensional definitions while even capturing the atmosphere of the scene.

The GFX100 uses oversampling with the amount of data equivalent to approx. 50.5 million pixels to render video with exceptionally high resolution. It also supports the highly efficient H.265/HEVC compression codec as well as the “F-Log” mode that reproduces rich tonal gradation and the “Hybrid Log Gamma (HLG)” for recording HDR (high dynamic range) footage with ease.

For the first time in the GFX Series, GFX100’s Film Simulation options, which allow users to enjoy a variety of color and tonal reproductions, include “ETERNA” for simulating the colors and tones of Fujifilm’s cinema film. This enables faithful reflection of videographers’ artistic intentions to video production.

Video is recorded on an SD card at 4K 30P 10bit 4:2:0 and on external media via HDMI at 4K 30P 10bit 4:2:2.
The full potential of the 55mm diagonal length large format sensor in the GFX can be seen when shooting both stills and in video.

ISO Sensitivity

The standard ISO sensitivity range is ISO100-12800, with extended sensitivities of ISO50, ISO25600, ISO51200 and ISO102400. RAW format is supported at all ISO settings. The AUTO function allows you to set the standard ISO, low shutter speed limit and upper ISO limit, and configure AUTO 1 – 3 settings according to shooting conditions.
  • Still: Standard Output: AUTO1 / AUTO2 / AUTO3 (up to ISO12800) / ISO100 to 12800 (1/3 step)
    Extended Output: ISO50 / 25600 / 51200 / 102400
  • Movie: Standard Output: AUTO (up to ISO12800) / ISO100 to 12800 (1/3 step)
    Extended Output: ISO25600

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 most cinema cameras, produces a shallow depth of field, enhanced tonal gradient in 10-bit output, and greater ISO sensitivity.

The large format size produces video footage with more detailed textures while reproducing three-dimensional definition. 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), compression codecs such as H.265 and H.264, and a bit rate of up to 400Mbps.

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.
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 *3. 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.
The GFX100 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 color information attained in 10-bit color depth, the camera records premium quality footage faithfully depicting scenes even with a large brightness range or subjects with high color saturation.

Despite featuring the large format image sensor and IBIS, the GFX100’s camera body is compact and lightweight measuring just 48.9mm at the thinnest part and weighing approx. 1,400g*8. The compact form factor, equivalent to that of digital single-lens reflex cameras with a 35mm full-frame format sensor, ensures excellent mobility.
The camera body is highly robust due to the use of magnesium alloy and the “inner frame” structure of coupling the image sensor, IBIS and lens mount into an integrated unit. Weather-sealing is applied to 95 locations to make the body highly resistant to dust, moisture and low temperatures, catering to the tough shooting conditions of professional photography.

For the first time in Fujifilm cameras, a vertical grip is built into the camera body, making it stable and comfortable to hold.
Ability to display diverse shooting data for added comfort in camera operation
The GFX100 has a new 2.05-inch sub monitor on the rear panel in addition to the main 3.2-inch LCD monitor that can be tilted to three directions. Exposure settings and various other shooting data can be assigned to the rear-panel sub monitor so that the main monitor can be dedicated to checking frame, allowing you to concentrate on composition.

The top panel now features another new 1.80-inch sub LCD monitor, which can be set to the “Virtual Dial Mode,” displaying a virtual dial for simulated operation. This is a perfect function for users who prefer dial-based operations, adopted in GFX Series’ current models.

The number of dials, buttons, and levers on the camera body has been kept to the minimum for simplicity in camera operation. The top panel features the Drive Mode Dial, which enables instantaneous switchover between the Still Image, Video and Multiple Exposure modes. Each of these modes can store settings such as exposure settings, white balance and Film Simulation selection. That means it only requires just single dial action to recall optimum camera settings, ensuring ease of camera operation.

Featuring the world’s top-class ultra-high definition electronic viewfinder (EVF) with more than 5.76M million dots for accurate focusing
The GFX100 features an ultra-high definition EVF, newly-developed for this model using the world’s top-class 5.76 million-dot OLED panel and five optical glass elements including aspherical elements. With the viewfinder magnification of 0.86x and 100% viewfinder coverage, the EVF enables accurate focusing for the 102 million pixels sensor, which requires extreme focusing accuracy.
The GFX100 inherits FUJIFILM GFX50S’s popular detachable EVF system. When the optional EVF Tilting Adapter EVF-TL1 is attached, the EVF can be tilted to variable angles to provide flexibility accommodating user preference.
The EVF can be set to the “Frame Rate Priority,” “Resolution Priority” or “AF Speed Priority” mode according to subject characteristics.
Support for “16bit RAW” and “16bit TIFF” to cater to the needs of professional photography
The GFX100 has responded to requests by many professional photographers by allowing photos to be saved in “16bit RAW” and “16bit TIFF”, significantly improving photo data’s tolerance to post-processing*9. This means the camera’s rich tonal gradation and Fujifilm’s unique color reproduction modes can be effectively utilized at the forefront of professional photography.
The GFX100 also features the newly-developed “Smooth Skin Effect” function, which automatically smooths the skin tone. It reduces the amount of post-processing work in portraiture so that images can be finished at an advanced level of perfection much quicker than ever before.
*9 Tolerance to image degradation caused by post-processing
Accommodating two batteries and supporting USB charging / powering for enhanced user convenience
The GFX100 can accommodate two GFX Series batteries (NP-T125), 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 USB 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.

This is the first GFX Series model that has a supporting IEEE802.11ac 5GHz, enabling even faster wireless image transfer. For RAW processing and tethered shooting, similarly to previous GFX Series models, the GFX100 is compatible with “Tether Shooting Plug-in PRO for Adobe® Photoshop® Lightroom®” and “Capture One Pro FUJIFILM” to accommodate the diverse workflow of professional photographers.
