After making a development announcement at the 2018 Photokina, Fujifilm has launched its 100 megapixels GFX system digital medium format mirrorless camera. The GFX 100 is a very different design from the existing GFX 50S, with dual handgrips and dual batteries, but it retains a detachable EVF and a fully-weatherised magnesium alloy bodyshell. It’s quite a lot bigger than the 50 MP cameras, but still comparatively compact for a digital medium format camera and is certainly a lot more portable that its direct competition, Phase One’s XF with the 100 megapixels IQ4 Trichromatic capture back. The difference in pricing is even more dramatic.
The GFX 100 is Fujifilm’s third GF mount model and has an all-new CMOS sensor in the 33x44 mm format with an effective pixel count of 102 million. It’s a backside-illuminated (BSI) type – a first at this size – and delivers a maximum image size of 11,648x8736 pixels with the option of capturing 14- or 16-bit RAW files.. There are a number of digital medium format ‘firsts’ associated with this camera, starting with the sensitivity range which spans ISO 100 to 12,800 with extensions to ISO 50 and 102,400. Then the camera’s ‘X Processor 4’ delivers continuous shooting at up to 5.0 fps and 4K video recording in both the DCI and UHD resolutions at 25 fps with a bit rate of up to 400 Mbps. Additionally, the GFX 100 has in-body image stabilisation which represented quite a challenge given the weight of the sensor module, and it requires its own dual processors. There’s five-axis shifting and correction for camera shake of up to 5.5 tops. Another significant first is the provision of on-sensor phase-difference detection pixels which deliver near full-frame coverage, enabling the provision of subject tracking with continuous autofocusing. The GFX 100 also has the ‘AF-C Custon’ menu – as on the X-T3, for example – which allows for the tracking to be fine-tuned to the type of subject movement. There’s also the latest version of Fujifilm’s eye/face detection with tracking.
Along with the portability, all this adds up – for the first time – to a digital medium format camera that’s being promoted for outdoor and action photography applications. Seriously. The camera’s focal plane shutter runs up to 1/4000 second, but there’s also a sensor-based shutter which has a top speed of 1/16,000 second. Flash sync is up to 1/125 second.
Elsewhere, the GFX 100 has pretty much the same suite of features as the top-end X models, including 16 ‘Film Simulation’ profiles, the Grain and Colour Chrome effects plus ‘Smooth Skin’ effect, the ‘B&W Adjust’ toning, a selection of auto bracketing functions (including for focus), an intervalometer and in-camera battery charging via USB-C.
Talking of power, the GFX 100 uses a pair of the N-PT125 lithium-ion battery packs housed in a detachable tray so they’re easily replaced mid-shoot. Fujifilm claims up to 800 shots are achievable from the packs when fully-charged.
With batteries and memory cards loaded, the body weight is 1.4 kilograms, including the EVF which, as with the GFX 50S, is detachable. The optional tilt/swing adapter already available for the 50S can be used. The new standard finder has a chart-topping resolution of 5.76 megadots and a magnification of 0.86x (35mm equivalent). It’s an OLED-type panel with adjustments for brightness, colour saturation and colour balance. Incidentally, it can't be used on the GFX 50S. The monitor screen is an 8.1 cm LCD panel with a resolution of 2.36 megadots and touch controls. The tilt adjustment is the same three-way arrangement as on the GFX 50S and X-T3. There are dual card slots for the SD format with UHS-II support. The wireless connectivity is via both WiFi and Bluetooth LE. The physical connectors are USB Type C, HDMI Type D and 3.5mm stereo audio in and out.
On the subject of video, the GFX 100 also boasts a number of firsts for a digital medium format camera. The 4K DCI and UHD recording options have already been mentioned, but there’s also F-Log and HLG gamma profiles, 10-bit 4:2:2 colour to the HDMI output (with simultaneous 10-bit 4:2:0 recording internally). There’s the choice of the H.264 and H.265 codecs and All-Intra or Long GOP compression regimes.
The GFX 100 will be available in Australia from the end of June, priced at $16,499 body only. For more information visit http://www.fujifilm.com.au
