Nikon D810 vs Sony a7S II Overview and Optics

The Nikon D810 outperforms the Sony a7S II in optics with a score of 76/100 compared to the Sony’s 66/100. Both cameras share several common specifications, such as a shooting speed of 5, a CMOS sensor type, and a full-frame sensor size. Additionally, both cameras use different lens mounts – the Nikon D810 with Nikon F FX and the Sony a7S II with Sony FE.

The Nikon D810 excels in several aspects, including a higher megapixel count of 36.3 compared to the Sony a7S II’s 12.2, resulting in more detailed images. The D810 also has a superior DXOMARK sensor score of 97, indicating better overall image quality. Moreover, the Nikon D810 is equipped with the Expeed 4 processor, which further contributes to its image quality.

On the other hand, the Sony a7S II has some advantages, such as built-in image stabilization, a feature absent in the Nikon D810. This allows for steadier shots and can help reduce camera shake, especially in low-light situations. The a7S II also uses the Bionz X processor, which, while not as powerful as the Expeed 4, still delivers good image quality.

Taking these factors into account, the Nikon D810 is the superior choice in terms of optics due to its higher megapixel count, better DXOMARK sensor score, and Expeed 4 processor. However, the Sony a7S II should not be overlooked, as its built-in image stabilization and Bionz X processor provide solid performance. Ultimately, the choice between these two cameras comes down to the individual’s priorities and preferences in terms of image quality and stabilization.

Nikon D810 vs Sony a7S II Video Performance

The Nikon D810 outperforms the Sony a7S II in video capabilities with a score of 70/100 compared to the Sony’s 56/100. Both cameras offer high-quality video recording, but there are key differences in their specifications that set them apart.

The Nikon D810 and Sony a7S II share some common video specifications. Both cameras have a maximum video resolution of Full HD (1920 x 1080), and each has built-in features for video recording. However, the similarities end there.

The Nikon D810 has a higher maximum video frame rate of 60fps, allowing for smoother video playback compared to the Sony a7S II, which has a maximum frame rate of 30fps. Additionally, the Nikon D810 has built-in time-lapse functionality, which the Sony a7S II lacks.

Despite its lower video score, the Sony a7S II does have an advantage in its 4K video resolution (3840 x 2160), offering four times the resolution of Full HD. This means that the Sony a7S II can capture more detail in its video recordings compared to the Nikon D810. However, this advantage is diminished by the lower maximum frame rate and the lack of time-lapse functionality.

Taking all of these factors into account, the Nikon D810 emerges as the superior choice for video capabilities due to its higher maximum frame rate and built-in time-lapse functionality. While the Sony a7S II does offer 4K video resolution, it falls short in other crucial areas. The Nikon D810 provides a more versatile and user-friendly video recording experience, making it the better option for those prioritizing video capabilities in their camera choice.
