 Image quality

Yes GFX50 S really stunned! Look at the effective resolution of the camera 51 MP sensor which means this Fuji camera is the camera for those photographers whose primary demand is stunning image quality in any kind of photography situation. As GFX50 S employs 51mp resolutions and its remarkable medium format sensor is assuring sharp and clear images with exceptional details. On the other hand, Sony A7R III may not produce the same standard of images as GFX 50S, because Sony has lesser resolution and smaller sensor size as well (42 MP and Full-Frame sensor)

AF system

You can see from the table that Fuji is restricted to only contrast detect system, but the user of Sony will enjoy shooting with the A7R III’s inventive hybrid AF system. The huge benefit of using Sony over Fuji is that it uses hybrid AF system (Contrast + phase), so that the users can achieve quick and accurate focus of the target subjects. And after that the inventive 399AF points of A7R III, which works together with 425 contrast AF points to achieve faster tracking and focus response. Sadly, Fuji GFX50 S has only 117 contrast AF points.

Shutter speed

Fuji GFX 50S offers the shutter speed of 1/16000 sec, this shutter speed is enough for the required situation (Capturing fast moving actions) and an electronic shutter allows the use of shutter speeds up to 1/16000 sec. for working in bright light conditions. And A7R II offers shooting speed of 1/8000 seconds.

Continuous shooting speed

Sony A7R III offers maximum 10fps while shooting at Full resolution, whereas Fuji GFX 50S uses 3fps means if a photographer wants to capture the fast actions from any sports event or the actions of any sports player then A7R III is the great camera for that can meet their demands. If shooting is done in live view then it offers 8fps is also possible.


A photographer has to satisfy with the limited Full HD 1080p recording at 30 fps  with Fuji camera, but the Sony allows their users to record the 4K video at 30fps means they can get much more details and clarity in your video and the picture will look even better compared to the HD of medium Format GFX 50S


With Sony A7R III you can take only 650 shots at a time, whereas Fuji X50 S lets you take around 400 shots only.


You can say Sony has dedicated AF system in Sony A7R III for fast focusing and tracking performance. Fuji is recommended for the landscape and portrait photographers, whereas Sony is for those who want mirrorless camera for sports photography with 4K option. Whereas, the base ISO of Fuji GFX50 S might go better, all due to its enormous size sensor, means along with sharpness and clarity the images will also not miss even tiny details of the desired subjects,  However, the price of Sony is comparatively lesser than Fuji, the massive factor!
