Fujifilm GFX100 II

The Fujifilm GFX100 II is a medium format mirrorless camera produced by Fujifilm with Fujifilm G-mount. It is the direct successor to the 2019 GFX100.

The GFX100 II was announced on 12 September 2023 at the X Summit Global 2023. Sales commenced in September 2023.

Camera body / battery
The GFX100 II has a noticeably smaller and slightly lighter body than the GFX100, mainly due to the fact that the vertical grip is now an optional add-on. Whereas the GFX100 supports two batteries, the GFX100 II provides space for only one NP-W235 Li-ion type battery (same type as GFX100S). The GFX100 II body thus weighs 1,030 g with its single battery, one of two memory cards and EVF attached. This is approximately 370 g lighter than the GFX100 body (1,400 g with two batteries, memory card and EVF).

Viewfinder
The enhanced electronic viewfinder (EVF) (9.44 MP) is detachable, as that of the GFX100, and may be supplemented with an optional tilt accessory.

Sensor
The Fujifilm GFX100 II uses a newly developed high-speed 43.8 x 32.9 mm medium format sensor with 100% phase-detection autofocus coverage. The 102 MP resolution is identical to that of its predecessor, Fujifilm GFX100. In combination with the enhanced image processing engine "X-Processor 5" the camera can deliver up to double the signal readout speed compared to the sensors employed by both predecessors (Fujifilm GFX100 and GFX100S).

Stabilizer
The GFX100 II contains an in-body image stabilization (IBIS) mechanism with 5-axis stabilization. The manufacturer claims a shake compensation effect of up to 8.0 stops.

Rear monitor / top screen
The 3.2 inch, 2.36 M pixel, three-way tilting, colour LCD, touch screen rear monitor is very similar to the GFX 100's. The 2.09 inch high-contrast monochrome top screen enables checking camera settings at a glance, even in bright sunlight, and may be customized to display display virtual dials (aperture, shutter speed, ISO), a live histogram, or other information.

Dust and weather resistance
The build quality is high-class with the manufacturer claiming enhanced dust and weather-resistant capabilities. The camera is fully operative at temperatures from a maximum 40 °C to as low as -10 °C.

Storage formats
Still images may now also be stored as HEIF format (4:2:2 10bit) besides JPEG, TIFF, and Raw (Fujifilm .RAF) formats.

Pixel shift / multiple exposure / bracketing
The camera is equipped with a Pixel shift multi-shot capability, which allows its sensor to move incrementally thus enabling both true-colour and ultra-high resolution images (400 MP). It enables taking multiple exposures (up to 9 frames with a variety of overlay modes) and also supports 6 different bracketing modes (AE bracketing, film simulation bracketing, dynamic range bracketing, ISO sensitivity bracketing, white balance bracketing, focus bracketing).

As opposed to the other straightforward bracketing modes focus bracketing comprises two distinct variants: manual and auto.
 * Manual focus bracketing: set time interval between shots, step size, number of frames, and nearest focus position.
 * Auto focus bracketing: set time interval between shots, define nearest focus point and then the most distant focus point. Step size and number of frames are calculated automatically.

Video
This camera is capable of recording 4K video using the full sensor and can also natively capture 8K video, albeit with a 1.53× crop, utilising a roughly 29 mm x 16 mm sized region of the sensor. Higher-quality codecs require either fast CFexpress Type B cards or that video output be directly routed via USB-C cable to an external SSD.
 * 4K video may be set to 16:9 or 17:9 output
 * 8K video may be set to 16:9, 17:9, or 2.76:1 output
 * Other intermediate and lower resolution modes available

As to be expected for a high resolution medium format sensor, rolling shutter is more pronounced in comparison to lower resolution full frame sensors.

Lenses
The native Fujifilm G-mount lenses manufactured by the Fujifilm company bear the official designation Fujinon GF, as inscribed on the perimeter of the lens barrel. This Fujifilm G-mount table lists not only Fujinon lenses, but also G-mount-compatible lenses presented by other manufacturers.
