Nikon D810 vs Sony a7R III Overview and Optics

The Sony a7R III outperforms the Nikon D810 in optics, scoring 84 out of 100 compared to the D810’s 76. Both cameras share some common specifications, including a full-frame CMOS sensor, but there are notable differences that contribute to the Sony’s superior performance.

The Sony a7R III boasts a higher megapixel count at 42.4, compared to the Nikon D810’s 36.3, enabling it to capture more detail in images. Additionally, the a7R III has a faster shooting speed of 10 frames per second, doubling the D810’s 5 frames per second. This allows the Sony camera to capture fast-moving subjects more effectively. The a7R III also has a higher DXOMARK score for its sensor at 100, compared to the D810’s 97, indicating better overall image quality.

One advantage the Nikon D810 has over the Sony a7R III is its Nikon F FX lens mount, which provides access to a wider range of lenses compared to the Sony FE mount. However, the Sony a7R III features image stabilization, which the Nikon D810 lacks. This helps reduce camera shake and improve image sharpness, particularly in low-light situations.

Taking these factors into account, the Sony a7R III emerges as the superior choice for optics due to its higher megapixel count, faster shooting speed, better sensor score, and image stabilization. The Nikon D810’s main advantage lies in its lens compatibility, but this is not enough to surpass the Sony’s overall performance in this category.
