Fujifilm has recently announced the new GFX100S medium format camera. It is a compact variant of the original GFX100 model, significantly reducing the overall size to a common mirrorless shooter, while also featuring the brand’s more advanced imaging technology.
The Fujifilm GFX100S measures 5.9-inches wide, 4.09-inches tall, 3.4-inches deep, and weighs approximately 900 grams with battery and SD card included. Additionally, it is constructed with a magnesium alloy casing and is made to operate in temperatures as low as -10 Celcius. The camera is also claimed to be dust and water resistant, but no rating was provided.
In terms of framing assistance, the GFX100S comes with an eye sensor-equipped 0.5-inch OLED electronic viewfinder with a resolution of approximately 3.69 million dots, 23mm eyepoint, 0.77x magnification and 38-degree view angle. On its back is a tiltable 3.2-inch LCD touchscreen with 2.36 million-dot resolution.
The new camera is equipped with the same back-illuminated 102MP sensor as the original, which is enhanced by the high-performance quad-core Fujifilm X-Processor 4 CPU. It has a standard ISO range of 100 – 12,800 (1/3 step) for both stills and video, and features an updated focus tracking algorithm for its built-in autofocus (AF) systems. For the latter, the company claims that the GFX100S’ on-sensor phase-detection pixels cover nearly 100% of the onboard sensor, enabling it to acquire focus in as little as 0.18 seconds even in low light conditions.
Also featured on the device is a newly designed in-body image stabilisation (IBIS) system that further enhances visual stability when used in handheld situations. Specifically, it is a five-axis system which provides 6-stops of CIPA-rated image stabilisation, and is also noted to be 20% smaller and 10% lighter than the one featured on the original GFX100.
The new camera is capable of recording 4K videos up to 30fps in 16:9 and 17:9 aspect ratios in either H.264 or H.265 codecs. In addition, it can output 4K30p footage in either 10-bit 4:2:2 F-Log or 12-bit Apple ProRes RAW via HDMI out and an external monitor recorder. Concurrently, videos can also be recorded internally to an SD card at bit rates of up to 400Mbps in 10-bit 4:2:0 F-log. Fujifilm says that it included 19 Film Simulation modes built into the device as well, including the new Nostalgic Neg mode.
