Canon EOS 6D Mark II vs Sony a7R II Overview and Optics

The Sony a7R II comes out on top in the optics comparison with a score of 81/100, while the Canon EOS 6D Mark II scores 69/100. Both cameras share several specifications, including full frame sensor size, CMOS sensor type, and respective lens mounts (Canon EF for the 6D Mark II and Sony FE for the a7R II).

The Sony a7R II excels in several aspects, such as a higher megapixel count of 42.4 compared to the Canon’s 26.2, which translates to better image resolution. Additionally, the a7R II has a superior DXOMARK sensor score of 98, compared to the 6D Mark II’s 85, indicating a better overall sensor performance. Another important advantage of the Sony a7R II is the presence of image stabilization, which is absent in the Canon 6D Mark II. This feature helps to reduce camera shake and produce sharper images.

On the other hand, the Canon EOS 6D Mark II has a faster shooting speed of 6.5 frames per second (fps) compared to the Sony a7R II’s 5 fps. This can be advantageous in capturing fast-moving subjects or situations where a quick response is necessary. The Canon 6D Mark II is also powered by the Digic 7 processor, while the Sony a7R II uses the Bionz X processor, although it is not clear if this results in any significant performance differences between the two cameras.

Taking into account the various factors discussed, the Sony a7R II emerges as the superior camera in terms of optics, with its higher megapixel count, better sensor performance, and image stabilization. However, the Canon EOS 6D Mark II still holds its own with a faster shooting speed, making it a suitable choice for certain scenarios.
