Fujifilm GFX100 (22)

Quick Verdict

The Fujifilm GFX100 offers a number of world firsts, including a medium-format 100mp BSI CMOS sensor, with phase detection built-in, in-body image stabilisation, and 4K / CINE-4K video recording. All of this would be pretty pointless if the camera system didn't have lenses capable of using this, but after looking at the results produced, we were left incredibly impressed. The camera body and layout of controls, make the camera easy to use, with the camera giving excellent results straight from the camera. If you can afford it, then the GFX100 should be top of your list, if you're looking for the ultimate in image quality and resolution.

Fujifilm GFX 100 Features

Fujifilm GFX100 (17)

When first shown at Photokina 2018, the Fujifilm GFX 100 was introduced as a full-size medium-format mirrorless camera, with the headline feature of a 100mp medium format sensor, with built-in in-body image stabilisation (IBIS), and 4K video. Building on top of the Fujifilm GFX system, which has a range of G-mount lenses, and two other GFX camera bodies, the original GFX 50S (RRP £6199 body only), and the newer, more compact GFX 50R (RRP £3999 body only), both 50mp medium format mirrorless cameras. 


The Fujifilm GFX100 offers three "World's Firsts" including:

  • World's first medium format camera to feature in-camera sensor-shift image stabilisation
  • World's first medium format camera to feature phase-detection pixels built-in to the sensor
  • World's first medium format (43.8mmx32.9mm) mirrorless digital camera to support 4K video recording (4K/30P).


You could also add to that, that it's the World's cheapest 100mp medium format mirrorless camera, being priced at £9999, 3x less than the nearest competitors.  It's also the first medium format camera to feature a BSI CMOS sensor (with phase detection), for improved low-light and noise performance. 


The Fujifilm GFX100 is the World's cheapest 100mp medium format mirrorless camera, being priced at £9999, 3x less than the nearest competitors.


Like the GFX 50R, the camera offers a removable electronic viewfinder (EVF), and a cover for when it's not attached. The electronic viewfinder offers an impressive resolution of 5.76million dots, and a magnification of 0.86x. There's dioptre correction, and an eye-detection sensor so the camera will automatically switch between the rear screen and EVF. 


Fujifilm GFX100 (12)

The 100mp BSI CMOS sensor measures 43.8x32.9mm, and features 3.76micron pixels, smaller than found in the GFX 50S/R, however this should be off-set by the BSI CMOS sensor technology helping to counter-act this, potentially giving no noise performance penalties due to the smaller pixel size. 

Phase-detection focus is built-in to the sensor, with 3.76million phase detection pixels, covering the whole sensor. 

The GFX 100 has P, Aperture-priority, Shutter-priority, and full manual shooting modes, but to access them you either adjust the aperture (on the lens, or rear control wheel), adjust the shutter speed, and adjust the ISO speed, there's no dedicated mode dial in the traditional sense, however you can switch between Movie / Multi and Stills shooting on the top left of the camera. The camera offers multiple-exposure shooting, as well as focus stacking options. 

There are numerous colour settings available, including Fujifilm's famous film modes, which includes Provia, Velvia, Astia, Classic Chrome, Pro Neg Hi, Pro Neg Standard, Eterna / Cinema, Acros, Monochrome, and Sepia. You can also apply a grain effect, colour chrome effect, or a skin smoothing effect.

Fujifilm GFX100 (19)

There are a good number of lenses available for the system, especially considering the GFX system was first announced in 2016, Fujifilm has done an excellent job of bringing a good number of appealing lenses to the market. 

As mentioned, the camera records both 4K UHD video and DCI 4K (CINE) video - the camera also records 10bit 4:2:2 externally and 10bit 4:2:0 internally, and the camera supports 4K / DCI-4K at 30, 25, 24, and 23.98p. You can also record FullHD video at frame rates up to 60fps (59.94p), in 17:9 or 16:9 aspect ratios. The Eterna film simulation mode can be used to give the look of cinema film, with a flatter colour profile (and great dynamic range). The camera uses the full sensor width to record video, and supports simultaneous output to HDMI and the internal SD card. You'll also find microphone and headphone sockets on the side. 

Wi-Fi and Bluetooth are built-in, letting you remotely control the camera, add geotagging information from your smartphone, print to an Instax printer, and more.

Fujifilm GFX 100 Handling

Fujifilm GFX100 (3)

The Fujifilm GFX 100 may be described as a "compact and lightweight body" by Fujifilm, but it still weighs in at 1400g with EVF, battery (x2) and memory card. Without the viewfinder it's 80g lighter. This makes the camera quite heavy, especially once you combine it with a lens, such as the GF 32-64mm lens, which weighs 875g or the GF 110mm f/2 lens, which weighs 1010g. Compared to a more traditional medium format camera such as the Hasselblad H6D-100C, it is definitely lighter, with the H6D-100C weighing 2130g (body only). The GFX 100 is only slightly heavier than the Canon EOS 1DX Mark II, which weighs 1340g.

The camera body is weather-sealed, and has a magnesium alloy body. It feels extremely solid, with a good sized grip, with plenty of textured rubber grip. On the side you'll find dual SD card slots, and the use of UHS-II memory cards is recommended due to the increased read and write speeds offered. 

The top left of the camera features the lockable drive mode dial, with a button that needs to be pressed before you turn this. Once you press this you can switch between stills, movie and multi modes, with the multi mode being setup up to give you access to both movie and stills modes. The Drive button lets you choose between single shot mode and continuous shooting modes, with the choice of continuous high or continuous low. The camera can shoot at 5fps (continuous high) letting you shooting 41 JPEG frame, or 14 RAW (Lossless compression) frames, or 13 RAW Uncompressed Frames.

What you'll find is that when you pick up the camera is just how easy it is to use, with everything falling to hand, with the controls where you would expect them. Some have complained about the size of the buttons, however, we found them logically laid out, and the size was not an issue for us. It's likely that if you're in poor weather conditions and wearing gloves then the size of some of the buttons may be an issue for some. 


Fujifilm GFX100 (7)

The top screen gives you a number of different views, but the view we preferred was one with two virtual dials, one showing the ISO speed selected, and the other the shutter speed - pressing the button to the right of this switches between auto and manual shutter control. You can turn the ISO dial to set it to Auto (1,2, or 3) or set it to a specific setting. The unlabelled, but smaller button to the lower right of this screen lets you change the display mode of this screen. The rear LCD display under the main screen, shows current camera settings at a glance.

The focus area covers the whole sensor and you can choose between 117 or 425 focus points. Focus is quite rapid, and importantly, very successful. Face and eye detection are built in, and there are also a number of manual focus assist modes unique to Fujifilm, including Digital Split image, Digital Microprism, as well as the more usual focus peaking. You can also choose to display a depth-of-field scale on-screen, plus customise continuous AF to adjust tracking sensitivity, speed tracking sensitivity, and zone area switching. 

The 3.2inch screen has a high resolution of 2.36million dots, and with a gapless design, viewing angles are very good, the display is clear and colours look good. Being able to tilt the screen up, down and sideways means it's more versatile than just a screen that tilts up and down, and the sideways tilt can be particularly beneficial when using the camera in portrait orientation. 

Fujifilm GFX100 Rear (3)

The electronic viewfinder (EVF) with a high resolution of 5.76million dots gives an impressive view with detail that is impressive, although you can still tell you're shooting using an EVF, as lights and screens can flicker (when indoors). The eye-detection sensor means the camera will automatically switch between the rear screen and the EVF and in use we didn't find any problems with delay. 

Menus – The menu system follows the same design and layout as other Fujifilm GFX and X series cameras, so if you're familiar with other Fujifilm cameras, it should be quick and easy to start using this. There's a "MyMenu" section so you can store your favourite settings / options for quick access, and the menus are neatly laid out into logical sections, with the video options having their own area. The Q button on the back gives quick access to some of the most common options, on the rear screen, so that you don't have to go in to the menus to change settings unnecessarily.  

Fujifilm GFX100 (11)

Battery life - Battery life is rated at 800 shots according to Fujifilm / CIPA test results (using the GF 63mm lens), which is good for a couple of days shooting, depending on how often you use the camera. The camera can be charged and powered through the USB-C connection, so if you do get stuck out and about a portable charge should help.

Wow at all of the specs - and the price.

BUT I can't believe for 10 thousand pounds they can't offer 8k or even 6k video. a 100 million pixels but about 92 million are thrown away for video. I suspect that it might have been too technically challenging to capture the sensor, downsize to 8k (properly) and record it to a card around 25 times every second.

I think that all the worries about the computing power needed to process these 100mp images are over-exaggerated, mostly. My 2012 machine handles them rather well. It only takes longer to export the results. However, it's not something a cheap laptop could easily digest. But then, if you are spending this kind of money on camera and lenses, you should be able to afford a proper computer too. The file size will cost you extra storage. But a pair of 10TB drives costs "only" around $600 now ($300 each). That's way cheaper than the memory cards that you'll use in this camera.
