The Sony a7R II outperforms the Canon EOS 6D with a score of 70/100 compared to 59/100. Both cameras share a few similarities, such as their announcement and release years (2012 for the Canon and 2015 for the Sony) and their respective launch prices ($2099 for the Canon and $3198 for the Sony).

The Sony a7R II’s higher score is due to its mirrorless design, which results in a smaller and lighter body (127 x 96 x 60mm and 625g) compared to the Canon EOS 6D’s DSLR build (145 x 111 x 71mm and 770g). However, the Canon EOS 6D has a lower launch price, making it a more affordable option.

Considering these points, the Sony a7R II stands out as a better camera with its compact and lightweight design, while the Canon EOS 6D remains a budget-friendly choice for those seeking a DSLR.

Canon EOS 6D vs Sony a7R II Overview and Optics

The Sony a7R II outperforms the Canon EOS 6D in optics, scoring 81/100 compared to the Canon’s 61/100. Both cameras share some common specifications, such as a full-frame CMOS sensor and a similar lens mount system (Canon EF for the 6D and Sony FE for the a7R II).

The Sony a7R II excels with its higher megapixel count (42.4 vs. 20.2), faster shooting speed (5 fps vs. 4.5 fps), and superior DXOMARK sensor score (98 vs. 82). Additionally, the a7R II features image stabilization, which the Canon 6D lacks. These factors contribute to the Sony a7R II’s higher score and better overall performance in optics.

However, the Canon EOS 6D does have some advantages, such as its Digic 5+ processor, which provides reliable image processing. Nevertheless, the Sony a7R II’s Bionz X processor is also highly capable, and the camera’s other superior features overshadow this aspect.

Taking all factors into account, the Sony a7R II clearly surpasses the Canon EOS 6D in optics quality. The higher score of 81/100 is due to its superior specifications, such as the higher megapixel count, faster shooting speed, better DXOMARK sensor score, and the presence of image stabilization. While the Canon 6D has a reliable processor, it does not compensate for its shortcomings in other areas. Therefore, the Sony a7R II stands out as the better option for those prioritizing optics performance.

Aspect Ratio
The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3.
Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
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.
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.
Maximum ISO (Expanded)

Canon EOS 6D vs Sony a7R II Video Performance

The Sony a7R II outperforms the Canon EOS 6D in video capabilities, scoring 56/100 compared to the Canon’s 43/100. Both cameras share some common features, such as a maximum video frame rate of 30fps and the lack of built-in time-lapse functionality. However, the Sony a7R II boasts superior specs, making it the winner in this comparison.

The main advantage of the Sony a7R II is its 4K video resolution, which is significantly higher than the Canon EOS 6D’s Full HD resolution. With a maximum video dimension of 3840 x 2160, the Sony a7R II captures more detail and provides sharper image quality, making it a better choice for professional videographers and enthusiasts alike.

The Canon EOS 6D, on the other hand, only offers a maximum video resolution of Full HD or 1920 x 1080. Although this resolution is suitable for casual video recording or sharing on social media platforms, it falls short when compared to the Sony a7R II’s 4K capabilities. The Canon EOS 6D’s lower video score reflects this limitation.

Despite the lower score, the Canon EOS 6D may still be a viable option for those seeking a more affordable camera or for those who do not require 4K video resolution. However, for users prioritizing video capabilities, the Sony a7R II is the clear winner in this comparison due to its superior video resolution and overall performance.
