With their $20,000 / £20,000 and upwards price tags, medium format cameras have pretty much been the realm of the professional photographer and enthusiasts with seriously deep pockets. There have been some exceptions – Pentax bought out the 645D in 2010, and while it was by no means cheap, it’s much more palatable price tag opened up medium format photography to a wider audience.
Fujifilm GFX 50S Full Specification, Features, Performance, Handling And Review
Unlike the 645Z, both cameras are mirrorless designs, and while this is a natural extension for Hasselblad, it might seem like a huge jump for Fujifilm. However, dig a little deeper and you’ll discover that Fujifilm has a rich heritage in medium format film photography – even making some Hasselblad-branded lenses for its medium format cameras.
- Medium format (43.8 x 32.9mm) CMOS sensor, 51.4MP
- 3.2-inch touchscreen, 2,360,000 dots
- 1/125 sec flash sync speed
You might be asking yourself “If I can get a 50.6MP full-frame Canon EOS 5DS DSLR, why should I be bothered about Fujifilm’s new GFX 50S?”. The simple answer is sensor size – with a sensor some 1.7x larger than a full-frame chip and measuring 43.8 x 32.9mm (producing 4:3 aspect ratio images), you get much bigger photosites (pixels). The result is better light-gathering capabilities, meaning we should expect to see better low-light performance and better dynamic range.
Unlike the X1D, the GFX 50S uses a regular focal plane shutter, so while the Hasselblad has the luxury of being able to flash-sync at any desired shutter speed, with the GFX 50S you’re restricted to a slightly more conservative limit of 1/125 sec.
Like the X1D, Fujifilm has opted for a mirrorless design with the GFX 50S, which means there’s an electronic rather than optical viewfinder for composition. The eye-level viewfinder packs in a large 0.85x magnification, with an impressive resolution of 3.69m-dots for a clear and bright view.
And that’s just half the story – thanks to the modular design of the GFX 50S, the eye-level viewfinder can be removed and replaced with an (optional extra) electronic tilting viewfinder that slots into the accessory port on the top of the camera.
Complementing the EVF is not only a 3.2-inch dual-hinged tilt-angle screen (similar to what we’ve seen with the X-T2) at the rear with 2,360,000-dot resolution and touchscreen functionality, but also a compact top plate LCD display that shows key shooting settings, battery status and how many shots are remaining on the card (the GFX 50S features dual SD card slots, compatible up to UHS-II).
Because the sensor is larger than that of a full-frame camera, there’s a 0.79x crop factor to take into consideration, so that 63mm is roughly equal to 50mm on a full-frame camera, while the 120mm is equivalent to 95mm.

The addition of a mechanical shutter means the Fujifilm GFX 50S’s body, despite being a mirrorless design, is quite substantial. Noticeably thicker than the X1D, it’s also that bit bigger and heavier than full-frame DSLRs like Canon’s EOS 5DS and the Nikon D810. Not so much, though, that it’s an issue – on a couple of occasions we bundled the GFX 50S, along with the 63mm and 120mm lenses, into a modest-sized shoulder bag and wandered around with it quite happily.
It doesn’t feel too cumbersome to pick up and hold either. The grip is a generous size, and overall you get a comfortable grip, while with the 63mm lens on the front the camera feels really nicely balanced.
You could be forgiven for thinking that a medium format camera could be a bit more daunting to use than a DSLR or mirrorless camera, but the reality is that if you’ve used a Fujifilm X-T2 or similar you’ll feel right at home with the GFX 50S.
There’s also a handy joystick for AF point selection (if you don’t want to use the touchscreen), while there’s the familiar ‘Q’ button for accessing some of the camera’s key settings.
On the whole, as we’ve come to expect from Fujifilm, the GFX 50S is a very well thought-out camera, but there are a couple of niggles. The arrival of the top plate LCD means there’s no place for an exposure compensation dial, which has been a typical Fujifilm design trait since the X100; it’s been replaced by a fiddly little button that sits just to the right of the shutter button, and it’s a bit awkward to use.
That little moan aside, the GFX 50S feels like an incredibly well made (the body is made from robust magnesium alloy, and is weather-sealed at 58 points to achieve a high level of resistance to dust and moisture) and photographer-orientated camera.
- Contrast-detect AF
- Total of 425 points available
- AF box size can be adjusted
Whereas we’ve seen numerous mirrorless cameras offer on-sensor phase-detection autofocus (such as Fujifilm’s own X-T2) for a hybrid system that combines the precision of contrast-detect AF with the speed of phase-detect, the GFX 50S opts solely for contrast-detect.
This isn’t too much of a surprise – the GFX 50S isn’t intended to be an action camera, rather a more considered photographic tool for landscape and studio work.
We found the AF performance to be very solid (though not lighting fast), locking on very accurately, particularly with the 120mm lens, but the system does begin to struggle under poor light, and will hunt as it attempts to acquire focus. This would all seem a bit pedestrian in a DSLR or smaller mirrorless camera, but if you’re prepared to be a bit patient with the GFX 50S, thanks to the results it’s capable of, you’ll get very precise autofocus acquisition.
- 3fps burst shooting
- Touchscreen integration works well
- 400-shot battery life
With the power switch located round the shutter release, a flick to the ‘on’ position sees the camera ready to shoot in about a second.
As we’ve mentioned, the GFX 50S isn’t a camera designed for those looking for out-and-out speed, so the tentative 3fps burst shooting speed is hardly a surprise – it’s perhaps fast enough to capture a subtle change of expression in a portrait if you hold the shutter down, but not to rattle off a burst of frames to capture anything more dynamic.
While not fast, the GFX 50S handles its large 117MB files with ease, happily writing files to the card without any slow-down in performance.
The TTL 256-zone metering system has been seen in numerous Fujifilm mirrorless cameras in the past, and it performs very well here, especially when challenged by high-contrast scenes, where if anything it tended to underexpose slightly. The chunky battery that slots into the side of the GFX 50S has a solid (for a mirrorless camera at least) 400-shot battery life, although pros working with the camera day-in, day-out will want to invest in a couple of spares.
- ISO100-12,800, expandable to 50-102,400
- Number of recorded pixels: 8256 x 6192
- 15 film simulation modes
This is where the GFX 50S really shines. The level of detail on offer from the 51MP sensor is simply breathtaking, with the large, densely populated sensor working in harmony with the razor-sharp Fujinon lenses.
That level of detail would be impressive in itself, but it’s when you factor in the breadth of the camera’s dynamic range that you can appreciate just how good the sensor is.
