Despite featuring a sensor which is 1.7 times larger than a 35mm full frame sensor, the GFX100’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).
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 color reproduction unique to FUJIFILM and the ultra sharp “FUJINON GF lenses.”
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 large format sensor which gives up to 5.5 stops of image stabilization.
Finder / Monitor
The GFX100 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 GFX100 high definition EVF
Colors / 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.
4K Movie / 10bit Color Depth
The full potential of the 55mm diagonal length large format sensor in the GFX can be seen when shooting both 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 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. You are 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), compression codecs such as H.265 and H.264, and a bit rate of up to 400Mbps.
Phase Detection AF System
The GFX 100 is the first GFX that features a phase detection AF system on 55mm diagonal length large format sensor. The GFX100 has phase detection pixels across the entire sensor and using 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 or in low light.
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.
Face Detection / Eye Detection
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.
EXIF / VOICE MEMO
Use the touchscreen panel to enter “Author” and “Copyright” to your file’s EXIF data. Record your voice for up to 30 seconds to make notes about the images you are shooting to keep track of your shoots.
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.
Interface for External Connections
The GFX100’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.
