Both Sony A7 IV & Canon R6 Mark II share many similarities, but there are also important differences, such as image quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Canon R6 Mark II rather than Sony A7 IV.

Why Do I Recommend Canon R6 II

  • The Canon R6 Mark II records 4K 60p video without any crop, while the Sony Alpha A7 IV applies a 1.50x crop to reduce the resolution and cut out parts of the original footage.
  • It offers a maximum ISO of 102,400, which increases the sensitivity of the sensor & allows for shorter exposure times than the Sony Alpha A7 IV’s maximum ISO of 51,200.
  • The Canon R6 Mark II has a pre-shooting buffer feature that allows the camera to start capturing and buffering images before the shutter button is pressed, whereas the Sony Alpha A7 IV does not have this feature.
  • The sensor pixel area of the Canon R6 II is 36.00µm² improves low-light performance compared to the 25.88µm² sensor pixel area of the Sony Alpha A7 IV.
  • Advanced Vehicle Tracking AF included in Canon R6 II that allows to easily lock and focus any vehicle automatically, but the Sony Alpha A7 IV lacks Vehicle Tracking AF features.
  • The Canon Mark II features an LCD screen with a resolution of 1,620k dots for better view, which is 12% higher than the Sony Alpha A7 IV’s 1,440k dots screen resolution.
  • It has a more advanced autofocus with 4897 autofocus points for making the focus area larger, allowing the camera to keep focus on the subject compared to the 759 autofocus points on the Sony Alpha A7 IV.
  • The R6 Mark II supports continuous shooting at 40.0 frames per second, which is 30 frames per second faster than the Sony Alpha A7 IV’s 10.0 frames per second.
  • Advanced Vehicle Tracking AF included in Canon R6 II that allows to easily lock and focus any vehicle automatically, but the Sony Alpha A7 IV lacks Vehicle Tracking AF features.
  • It offers extra functionalities, including Breathing Compensation, Focus Stacking, High-Frequency Anti-Flicker mode, and webcam mode; the Sony A7 IV does not.

Maybe the Sony A7 IV price can make you comfortable because it’s a little bit cheaper than the Canon R6 Mark II. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
