Canon EOS R6 vs Sony a7R IV Overview and Optics

The Sony a7R IV outperforms the Canon EOS R6 in optics, scoring 85/100 compared to the R6’s 79/100. Both cameras share some common specifications, such as the CMOS sensor type, full-frame sensor size, and image stabilization. They also have different lens mounts, with the Canon using the RF mount and the Sony using the FE mount.

The Sony a7R IV is superior in several aspects. It has a significantly higher megapixel count at 61.2, allowing for greater detail in images compared to the R6’s 20.1 megapixels. The a7R IV also boasts a higher DXOMARK score for the sensor at 99, indicating better overall image quality. The Bionz X processor in the a7R IV contributes to its improved performance in handling high-resolution images.

On the other hand, the Canon EOS R6 has a faster shooting speed of 20 frames per second, doubling the a7R IV’s 10 frames per second. This makes the R6 more suitable for capturing fast-moving subjects or action photography. The Digic X processor in the R6 allows for efficient handling of the camera’s shooting speed.

In terms of optics, the Sony a7R IV is the clear winner with its higher megapixel count and DXOMARK sensor score, making it the better choice for photographers who prioritize image quality and resolution. However, the Canon EOS R6’s faster shooting speed gives it an edge in action photography and situations where capturing rapid movement is crucial.

Canon EOS R6 vs Sony a7R IV Video Performance

The Canon EOS R6 outperforms the Sony a7R IV in video capabilities, scoring 91/100 compared to the Sony’s 70/100. Both cameras share some common specifications, including a maximum video resolution of 4K and dimensions of 3840 x 2160. Additionally, both cameras have built-in time-lapse functionality.

The Canon EOS R6 surpasses the Sony a7R IV mainly due to its higher maximum video frame rate of 120fps, which is significantly faster than the Sony’s 30fps. This difference allows the Canon EOS R6 to capture smoother, more detailed slow-motion footage, providing more creative possibilities for videographers.

While the Sony a7R IV may not match the Canon EOS R6 in terms of video frame rate, it still offers solid video performance. Its 4K resolution and time-lapse functionality are valuable features for many users. However, the lower frame rate does limit its versatility in comparison to the Canon EOS R6.

Taking these factors into account, the Canon EOS R6 emerges as the superior choice for video capabilities. Its higher frame rate provides more options for videographers, while still maintaining the same resolution and time-lapse features as the Sony a7R IV. On the other hand, the Sony a7R IV remains a competent option for video but falls short in comparison to the Canon EOS R6.
