Fujifilm GFX100S vs Sony a7R IV Overview and Optics
The Sony a7R IV outperforms the Fujifilm GFX100S in optics with a score of 85/100, compared to the GFX100S’s 78/100. Both cameras share several common specifications, including a CMOS sensor, image stabilization, and a similar processor (Bionz X for the Sony a7R IV and X-Processor 4 for the GFX100S). Despite these similarities, each camera has its unique strengths and weaknesses.
The Sony a7R IV boasts a higher optics score, mainly due to its faster shooting speed of 10 frames per second, compared to the GFX100S’s 5 frames per second. This makes the Sony a7R IV more suitable for capturing fast-moving subjects. Additionally, the Sony a7R IV has a DXOMARK sensor score of 99, providing a reliable benchmark for its image quality. The GFX100S does not have a DXOMARK score, as DXOMARK does not score Fujifilm cameras.
On the other hand, the Fujifilm GFX100S has a higher megapixel count at 102, compared to the Sony a7R IV’s 61.2. This gives the GFX100S an advantage in capturing more detail and producing larger prints. Furthermore, the GFX100S has a medium format sensor, which generally provides better image quality and dynamic range than the full-frame sensor found in the Sony a7R IV. The GFX100S also has a 4:3 aspect ratio, which can be preferable for certain types of photography.
In comparing the optics of these two cameras, the Sony a7R IV is the winner, offering a faster shooting speed and a proven DXOMARK sensor score. However, the Fujifilm GFX100S has its advantages, such as a higher megapixel count and a medium format sensor. Depending on the specific needs and preferences of the photographer, each camera can provide distinct benefits.

Minimum ISO (Native) Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image. | 100 | 100 | |
Maximum ISO (Native) Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise. | 12,800 | 32,000 | |
Minimum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 50 | 50 | |
Maximum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 102400 | 102400 | |
Minimum Shutter Speed The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory. | 30 s | 30 s | |
Maximum Shutter Speed The maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries. | 1/ 4000 s | 1/ 8000 s | |
Autofocus Points Autofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings. | 425 | 425 | |
In-body Stabilization In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake. |   | | |
