The GFX Series’ use of 55mm diagonal length large format sensor (43.8 x 32.9mm) has paved the way for ultra high image resolution. The GFX100 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.

Processor

Image Processing Engine

The GFX100 uses the X-Processor 4, FUJIFILM’s latest image processing engine to quickly optimize the data from the 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 color 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.

Shutter

  • Focal Plane Shutter

    The GFX focal plane shutter is specifically designed for 55mm diagonal length large format mirrorless digital cameras. With a durability performance over 150,000 shutter actuations *1, it combines an electronic front curtain shutter with an exceptionally quiet mechanical shutter which has a maximum speed of 1/4000sec. The shutter system has been redesigned for the GFX100 to support the new large format CMOS sensor 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.

  • Shock Absorber

    The GFX100’s shutter has a shock absorption mechanism ideal for landscape photography, studio shooting and commercial photography, all of which are unforgiving to even the slightest of camera shakes. The shutter unit is suspended at the top, bottom, right and left and is able to absorb subtle shakes caused when the mechanical shutter is used. It also enables quicker shutter response, which is useful in a variety of shooting situations.

Synchronized shutter speed for flash
1/125sec. or slower

*1According to Fujifilm internal testing.*2The Electronic Shutter may not be suitable for fast-moving objects or hand-held shooting. Flash cannot be used.*3When using the electronic front-curtain shutter, the continuous shooting speed supports CL only, and using a high-speed shutter, the shutter switches to mechanical shutter. (Faster than 1/1250sec. to 1/4000sec.)

Image Stabilization

Image Stabilization

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

*4Based on CIPA standard. Pitch/yaw shake only. With GF63mmF2.8 R WR lens mounted.
