Fujifilm GFX 50S Performance

The performance section is where we look at the image quality performance of the camera. Additional sample photos and product shots are available in the Equipment Database, where you can add your own review, photos and product ratings.

Speed - We took a number of shots to test the camera's responsiveness, from switch on to first photo, shot to shot, focusing speed etc. We take a number of shots and then use the average to ensure accurate and consistent tests, making it easy to compare with other cameras.

Shutter Response 0.05secs
Wide - Focus / Shutter Response 0.3secs
Full zoom - Focus / Shutter Response 0.3secs
- with 63mm lens 0.4secs
- with 120mm lens 0.3secs
Switch on Time to Taking a Photo 1.0secs
Shot to Shot without Flash 0.8secs
Shot to Shot with Flash N/A
Continuous Shooting - JPEG
(shots before slow down)
3fps (8 shots before slowdown)
Continuous Shooting - Flash N/A
Continuous Shooting - RAW 3fps (4 shots before slowdown)

The camera slows to 2fps after 8 shots shooting JPEG, or 4 shots when shooting raw.


Fujifilm GFX 50S Sample Photos

Fujifilm GFX 50S Other sample images

Sample Photos - Colour reproduction is excellent with strong colour saturation, with the camera producing JPEG results that pop straight from the camera. Exposure and dynamic range are both very good, although you can expand the dynamic range recorded, by adjusting the DR options, with AUTO, DR100%, 200% and 400% options. There are options to adjust the colour, sharpness, highlight tone, shadow tone, and noise reduction. JPEG images are roughly 25mb in size, and raw images (uncompressed) are around 111mb in size, so a large and fast memory card is recommended. The camera produced some excellent results in every environment and situation that we used to shoot with it, whether that was in a studio, in low-light, or out in the Peak District. Face and eye detection also help with portrait shoots.


Fujifilm GFX 50S Lens test images

Lens Performance - Detail is stunning, outstanding, phenomenal, and simply breath-taking from the 63mm f/2.8 prime lens, with excellent sharpness from the centre of the frame right to the edges. The 120mm macro lens also performs extremely well, with sharp and detailed images produced, and smooth bokeh when shooting close up images. Optical image stabilisation provided by the lens helped keep the viewfinder image steady and helps with slower shutter speeds. There is excellent sharpness from the centre of the frame to the edges. Images from the 32-64mm lens are very good, although not quite as sharp as the prime lenses. 

The camera delivers great results, even when shooting in low-light and using higher ISO speeds. Looking through images we can't find any signs of chromatic aberrations or purple fringing, at all. We struggled to see any examples of lens flare, even when shooting without the provided lens hoods. Distortion is minimal, with no signs of vignetting. 

The camera offers "Lens modulation optimiser" which is designed to give sharper images and reduce the effects of diffraction. You can shoot with a mechanical shutter speed up to 1/4000s, with an electronic shutter speed available up to 1/16,000s. 


Fujifilm GFX 50S ISO test images

ISO Noise Performance - Noise performance is excellent from ISO50 to ISO6400, and even ISO12800 gives good results, straight from the camera with no further processing required. ISO25600 still gives usable results (depending on your needs), although noise does become more noticeable at this setting. ISO51200 is probably best avoided unless you’re prepared to process the images further. ISO102400 is best avoided as noise becomes high, and image quality is quite poor. There is a drop in dynamic range when shooting at ISO50. Noise reduction options available include +4 and -4, with the default option 0. 


Fujifilm GFX 50S White-balance test images

White Balance Performance - Auto White Balance (AWB) gives a warm result under tungsten lighting, and the tungsten preset gives a slightly better result, but results are still warm, and we'd recommend manual white balance for more accurate results. Under mixed light, the camera's AWB performs well, with best results possible under fluorescent lighting. The fluorescent presets are best avoided, as they tend to give a colour cast. Images show more detail than from other 50mp cameras with smaller sensors, such as the Canon EOS 5DS R, as well as the 42mp Sony Alpha A7R II.


Fujifilm GFX 50S Digital filters

Digital Filters - The DR100 and DR200 shots show a noticeable difference in dynamic range recorded, with the sky no longer overexposed in these images. There are a number of film modes available including: Provia (Standard), Velvia (Vivid), Astia (Soft), Classic Chrome, Pro Neg Hi, Pro Neg Standard, Black and White, Black and White (+ Yellow/Red/Green filter), Sepia, Acros, Acros (+ Yellow/Red/Green filter). There are also Grain and Colour Chrome effects with options of strong, weak and off. In-camera raw conversion makes it quick and easy to make changes in camera as well. 


Video - Video recording is at a resolution of 1080p, with 29.97/25/24 and 23.98fps available, with the camera recording stereo sound with built-in microphones. There are microphone and headphone sockets, as well as HDMI out. Image stabilisation is lens-based, so a tripod or steady base is recommended unless you are using a lens with OIS. 
Video is recorded at 36mbps, and quality is good, although isn’t going to be the first choice for a lot of people, as the camera doesn’t offer 4K video. There are options to adjust the mic audio level.

It has even have seven different aspect ratios! No need to imagine how a picture will look cropped, it does deliver the frame that suits the subject perfectly.
Plus a white balance setting for underwater photography.
-hopefully they would be offering a case too-
Bravo Fuji

The rendering of the foliage of the plane tree through the arch is particularly impressive.
