Fujifilm unveils medium format GFX100S: 102 MP, 5-axis IBIS, $ 6,000



Fujifilm has announced the GFX100S, a camera that takes the “breakthrough ideas” of the GFX100 and rethinks them with an emphasis on portability. The result is a compact, high-performance medium-format camera that is similar in size to full-frame equivalents and weighs just 1.9 pounds.

Fujifilm claims the GFX100S is more advanced than any camera in the GFX system to date and combines the best of Fujifilm imaging technology in a compact body.

102 megapixels

Fujifilm claims that the back-illuminated 102-megapixel sensor is powered by its high-performance quad-core X-Processor 4 processor. It should be noted that Fujifilm still insists on calling it a “large format” sensor, but it is actually a medium format sensor.

The GFX100S medium format sensor is about 1.7 times the size, and Fujifilm claims it is “enhanced” to be incredibly sensitive to light. The company claims that this gives it a significant advantage over smaller sensors when it comes to producing images with a shallow depth of field, dynamic range, faithful color reproduction and high ISO performance.

Fujifilm also incorporates 19 “exclusive” Fujifilm film simulation modes into the GFX100S, including the new “Nostalgic Neg”.

Recalling the new American color photography that appeared in the 1970s, Nostalgic Neg continues this movement by allowing image makers to explore the limits of photographic creativity through the deliberate use of color.

High performance autofocus

Fujifilm claims that the phase detection pixels on the sensor cover almost 100% of the GFX100S sensor and can acquire focus in as little as 0.16 seconds, even in low light levels down to -5, 5EV (tested specifically with the FUJINON GF80mmF1. 7 R WR lens). Moreover, thanks to the aforementioned X-Processor 4 processor, the GFX100S also has an updated focus tracking algorithm when using AF Tracking and Face / Eye AF.

Integrated 5-axis image stabilization

The GFX100S implements a newly designed IBIS system which the company claims significantly expands the capability of the camera in portable situations. Compared to the unit of the FUJIFILM GFX100, the IBIS mechanism inside the GFX100S is 20% smaller and 10% lighter. Despite this reduction of
size, the five-axis system provides 6 stops of CIPA image stabilization, an improvement of 0.5 stops over the GFX100.

Compact size and intuitive controls

The body of the GFX100S is 5.9 inches wide, 4.09 inches high, and 3.4 inches deep, which Fujifilm says is comparable to many full-frame cameras (although they stop before to say “mirrorless” full frame cameras). That said, it’s compact enough for a camera with a sensor of this size and an IBIS system behind it, which deserves praise. The GFX100S weighs 1.1 pounds less than the GFX100, but Fujifilm says it maintains the same level of still image and video performance despite the weight reduction.

The GFX100S is designed to operate in temperatures as low as 14 ° F (-10 ° C) and also to be resistant to dust and moisture. It is constructed with a magnesium alloy body which is purposefully 1mm denser around the lens mount compared to the GFX100, which provides additional support for G-mount lenses.

The camera features the classic PASM dial with six programmable custom options as well as an easy-to-access switch located next to the model’s dial to quickly switch between photo and video modes. The rear of the camera has a tilting 3.2-inch touchscreen LCD with 2.36 million dots.

Medium format video

The GFX100S can capture 4K video at up to 30 frames per second in 16: 9 format as well as 17: 9 in H.264 or H.265 format. Footage can be recorded at bit rates up to 400 Mbps to a 10-bit 4: 2: 0 F log recorded internally to an SD card, or transmitted to an external recording device via the camera’s HDMI port .

Speaking of HDMI output, when using an Atomos Ninja V monitor recorder, the GFX100S is capable of outputting 4Kp30 images through its HDMI port in 10-bit 4: 2: 2 F-Log or 12-bit Apple ProRes. RAW. Simultaneous output of RAW footage and F-Log or Hybrid Log Gamma (HLG) footage with a film simulation mode applied is also possible.

The GFX100S is expected to be available from March 2021 for $ 5,999.95, and an optional grip attachment will be available around the same time for $ 149.
