Canon EOS R vs Sony a7R III Video Performance

The Canon EOS R triumphs over the Sony a7R III in video capabilities with a video score of 70/100, a 14-point lead over the Sony a7R III’s score of 56/100. Both cameras share some common specifications, including a maximum video resolution of 4K and maximum video dimensions of 3840 x 2160. Additionally, both cameras can record at a maximum video frame rate of 30fps.

The Canon EOS R’s superior video score is due to its built-in time-lapse functionality. This feature allows users to capture stunning time-lapse videos without the need for additional equipment or software. The time-lapse function is a valuable asset for videographers and photographers who wish to create dynamic, time-compressed videos showcasing movement and change.

On the other hand, the Sony a7R III lacks built-in time-lapse functionality. This absence may not be a deal-breaker for some users, as time-lapse videos can still be created using external intervalometers or software solutions. However, the absence of this feature makes the Sony a7R III less convenient for time-lapse enthusiasts compared to the Canon EOS R.

Considering the video capabilities, the Canon EOS R holds an advantage over the Sony a7R III. Its higher video score and built-in time-lapse functionality make it a more attractive option for videographers looking for a well-rounded camera. While the Sony a7R III shares some similar specifications, its lack of built-in time-lapse functionality slightly diminishes its appeal in the realm of video creation.
