# Fujifilm GFX100S II

The Fujifilm GFX100S II is a mirrorless medium format camera produced by Fujifilm with Fujifilm G-mount. It is the direct successor to the 2021 GFX100S.
The GFX100S II was announced by the Fujifilm corporation on 16 May 2024 at the X Summit Sydney 2024 together with the X-T50 and two new lenses. Sales are to commence in June 2024. The retail price is set to USD 4,999, which is USD 1,000 less than the initial retail price for its predecessor back in 2021.

## Camera body / battery

The size of the GFX100S II is the same as its predecessor. The new body weighs slightly less at 883 g (1.947 lb) including battery (versus 900 g (2.0 lb)) and it now sports the same BISHAMON-TEX finish as the GFX top model GFX 100 II announced in 2023.
The GFX100S II has retained the single NP-W235 battery of the GFX100S, but the service range has been extended:
* 530 images (CIPA) versus 460
* 80 min. of 4k video recording as opposed to 60 min.

## Processor

The GFX100S II has the latest X-Processor5, which provides enhanced shooting speed, improved autofocus, reduced rolling shutter, and a higher-quality video mode. The mechanical burst speed rises from 5 to 7 fps.

## Sensor

The Fujifilm GFX100S II uses the GMX series' 102MP 43.8 × 32.9 mm, 11648 × 8736 pixel medium format sensor with 100% phase-detection autofocus coverage. Compared to its predecessor some improvements have been added, such as redesigned microlenses for enhanced autofocus and better image quality at the extreme edges, a faster readout speed, and the standard sensitivity lowered to 80 ISO. The extended lower ISO value has been reduced to 40.

## Autofocus / Stabiliser

The autofocus system of the Fujifilm GFX100S II now offers subject recognition for insects and drones. The Fujifilm GFX100S II contains an enhanced in-body image stabilization (IBIS) mechanism with 5-axis stabilization. The manufacturer claims a shake compensation effect of up to 8.0 stops in combination with compatible lenses.

## Viewfinder

The fixed OLED electronic viewfinder (EVF) has now been upgraded to 5.76M dots and a magnification ration of 0.84×. Coverage of image: 100%.

## Rear monitor / top screen

The 3.2 inch, 2.36 M pixel, three-way tilting, colour LCD, touch screen rear monitor is identical to that of the GFX 100S. The 1.8 inch high-contrast monochrome e-ink 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.

## Film simulation modes

In keeping with all Fujifilm digital cameras, the GFX100S II offers a wide range of film simulations, including the newly introduced REALA ACE, thus totaling 20.

## Pixel shift

The Fujifilm GFX100S II is equipped with a Pixel shift multi-shot capability, which allows its sensor to move in half-pixel increments thus enabling both true-colour and ultra-high resolution images (400 MP).

## Multiple exposure / Bracketing

The multiple exposure and bracketing capabilities of the Fujifilm GFX100S II remain unchanged versus its predecessor. Multiple exposures may be taken with up to 9 frames combining a variety of overlay modes. Six different bracketing modes are provided:AE bracketing, film simulation bracketing, dynamic range bracketing, ISO sensitivity bracketing, white balance bracketing, focus bracketing.

## Storage formats (stills)

Still images may now also be stored as HEIF format (4:2:2 10-bit) besides the previously available JPEG (Exif v2.3), TIFF (8/16-bit), and Raw (Fujifilm .RAF) (14/16-bit RAF) formats.

## Video

As its predecessor, the Fujifilm GFX100S II is capable of recording 4K video at 25 or 30 fps using the full sensor width.
* 4K video may be set to 16:9 or 17:9 output
* Other intermediate and lower resolution modes available
Both Apple ProRes 422 footage and other video output may be directly routed via USB-C cable to an external SSD. Likewise a ProRes RAW or Blackmagic Raw encoded data stream may be transferred over its HDMI socket to a compatible Atomos or Blackmagic external recorder.
A faster sensor output in comparison to its predecessor reduces rolling shutter and the maximum attainable quality is now 4K / 30 fps video with 10-bit 4:2:2 options (for either H.264 or H.265 modes), thus extending video sampling up to 720 mbps (megabits per sec.).
The GFX100S II has gained not only a new F-Log2 profile but also both waveforms and vectorscope displays to assist with proper video exposure.
