Despite its higher launch price of $2499, the Canon EOS R6 Mark II justifies the cost with its superior performance. On the other hand, the Sony a6400 offers a more affordable option at $900 without compromising too much on quality.

Taking all aspects into account, the Canon EOS R6 Mark II proves to be a better camera, while the Sony a6400 remains a solid choice for those on a budget.

Canon EOS R6 Mark II vs Sony a6400 Overview and Optics

The Canon EOS R6 Mark II outperforms the Sony a6400 in optics, with a score of 83/100 versus 68/100. Both cameras share common specifications, such as 24 megapixels, CMOS sensor type, and compatible lens mounts (Canon RF for EOS R6 Mark II and Sony E for a6400).

The Canon EOS R6 Mark II excels in several areas. Its full-frame sensor size provides superior image quality compared to the Sony a6400’s APS-C sensor. The EOS R6 Mark II also boasts a higher DXOMARK score of 91, indicating better overall sensor performance. The camera’s shooting speed of 40 is significantly faster than the a6400’s 11, allowing for quicker capture of action shots. Additionally, the EOS R6 Mark II features image stabilization, which the a6400 lacks, leading to steadier and sharper images.

The Sony a6400, while lagging behind the EOS R6 Mark II, has a slight advantage in megapixels at 24.2. However, this minor difference does not significantly impact image quality. The a6400’s Bionz X processor is inferior to the EOS R6 Mark II’s Digic X processor, contributing to the lower overall score.

Comparing the two cameras, the Canon EOS R6 Mark II is the clear winner in terms of optics, due to its full-frame sensor, faster shooting speed, and image stabilization capabilities. The Sony a6400, though slightly higher in megapixels, falls short in other critical areas, making it less desirable for those prioritizing superior optics.

The higher the number of megapixels, the more detail the cameras sensor can capture.

Canon EOS R6 Mark II vs Sony a6400 Video Performance

The Sony a6400 wins in the video capabilities comparison, scoring 91/100, while the Canon EOS R6 Mark II scores 83/100. Both cameras share common video specifications, including 4K max video resolution, 3840 x 2160 max video dimensions, and built-in time-lapse functionality.

The Sony a6400 outperforms the Canon EOS R6 Mark II in video frame rate, offering a maximum of 120fps compared to the Canon’s 60fps. This higher frame rate allows the Sony a6400 to capture smoother slow-motion footage, providing more creative flexibility for videographers.

Despite the lower score, the Canon EOS R6 Mark II still has great video capabilities. It matches the Sony a6400 in max video resolution, dimensions, and time-lapse functionality. However, the Sony a6400’s higher score is due to its superior video frame rate, which makes it a better option for those prioritizing video performance.

While the Canon EOS R6 Mark II falls short in video frame rate, it remains a solid choice for videographers looking for a camera with strong video capabilities. The Sony a6400, on the other hand, excels in this area, making it the ideal choice for those who need a higher frame rate for their projects. Both cameras offer impressive video features, but the Sony a6400’s higher score and frame rate make it the clear winner in this comparison.
