Canon EOS M6 Mark II vs Sony a6400 Overview and Optics

The Sony a6400 outperforms the Canon EOS M6 Mark II in optics with a score of 68/100 compared to the Canon’s 62/100. Both cameras share common specifications, such as a CMOS sensor, APS-C sensor size, and the lack of image stabilization. Additionally, both cameras have their own lens mounts, with the Canon using the EF-M mount and the Sony using the E mount.

The Sony a6400 is superior in terms of its sensor, as evidenced by its DXOMARK score of 83, compared to the Canon’s 58. This higher score means the Sony a6400 provides better image quality, particularly in low light situations. Furthermore, the a6400’s processor, the Bionz X, is known for its fast processing speed and efficient noise reduction capabilities.

On the other hand, the Canon EOS M6 Mark II has its advantages, such as a higher megapixel count (33 vs. 24.2) and a faster shooting speed (14 vs. 11). These features make the Canon more suitable for capturing detailed images and fast action scenes.

In terms of optics, the Sony a6400 is the better choice due to its higher DXOMARK score and superior processing capabilities. However, the Canon EOS M6 Mark II may be more appealing to those who prioritize higher resolution and faster shooting speeds. Ultimately, the choice between these two cameras depends on the specific needs and preferences of the photographer.
