The Sony a1 outperforms the Fujifilm GFX 50S II with a score of 86/100 compared to 79/100. Both cameras are mirrorless and were released in 2021. They share similarities in their design, but the Sony a1 is lighter at 737g and smaller at 129 x 97 x 81mm, making it more portable. Additionally, the Sony a1’s higher score reflects its superior performance and features.

On the other hand, the Fujifilm GFX 50S II has a lower launch price of $3999, making it more affordable than the Sony a1 at $6499. While the Sony a1 is the clear winner in terms of performance, the Fujifilm GFX 50S II offers a more budget-friendly option for those seeking a mirrorless camera.

Fujifilm GFX 50S II vs Sony a1 Overview and Optics

The Sony a1 takes the lead in optics with a score of 89/100, outperforming the Fujifilm GFX 50S II, which has a score of 77/100. Both cameras share some common specifications, such as a CMOS sensor, image stabilization, and a shooting speed of 3 for the Fujifilm GFX 50S II and 30 for the Sony a1. However, there are key differences that set these cameras apart in terms of optics.

The Sony a1 has a slight advantage in terms of megapixels, with 50.1 compared to the Fujifilm GFX 50S II’s 51. The Sony a1 also boasts a superior processor, the Dual Bionz XR, which contributes to its higher score. Additionally, the Sony a1 has a DXOMARK sensor score of 98, while the Fujifilm GFX 50S II does not have a DXOMARK score, as DXOMARK does not score Fujifilm cameras. This gives the Sony a1 a clear edge in image quality.

On the other hand, the Fujifilm GFX 50S II has a medium format sensor, which is larger than the full-frame sensor found in the Sony a1. This can result in better image quality and dynamic range in certain situations. The Fujifilm GFX 50S II also has a 4:3 aspect ratio, which may be preferable for some photographers compared to the Sony a1’s 3:2 aspect ratio.

Despite the advantages of the Fujifilm GFX 50S II’s medium format sensor and aspect ratio, the Sony a1’s higher score, faster shooting speed, and better processor make it a superior choice in terms of optics. The Fujifilm GFX 50S II is still a strong contender, but the Sony a1 stands out as the better option for those prioritizing image quality and performance.

Fujifilm GFX 50S II vs Sony a1 Video Performance

The Sony a1 outperforms the Fujifilm GFX 50S II in video capabilities, scoring 86/100 compared to the GFX 50S II’s score of 57/100. Both cameras share some common video features, but the Sony a1 has superior specifications in certain areas.

Both the Fujifilm GFX 50S II and the Sony a1 offer time-lapse functionality, which is a desirable feature for many videographers. However, the Sony a1 surpasses the GFX 50S II in terms of video resolution and frame rate. The a1 boasts an impressive 8K maximum video resolution with dimensions of 7680 x 4320, while the GFX 50S II only offers Full HD resolution with dimensions of 1920 x 1080. Additionally, the Sony a1 can record at a maximum video frame rate of 120fps, resulting in smoother, more realistic footage than the GFX 50S II’s maximum of 30fps.

The Fujifilm GFX 50S II does have a slight advantage over the Sony a1 in terms of built-in time-lapse functionality. While both cameras offer this feature, the GFX 50S II has it built-in, whereas the Sony a1 does not. This may be a small consolation for the GFX 50S II but does not make up for the significant differences in video resolution and frame rate.

Considering the significant differences in video capabilities, the Sony a1 is the clear winner in this comparison. Its superior video resolution and frame rate make it a better choice for videographers seeking high-quality footage. The Fujifilm GFX 50S II’s built-in time-lapse functionality is a nice feature, but it is not enough to compete with the Sony a1’s overall video performance.
