The Sony a1 takes the lead with a score of 86/100, while the Canon EOS R3 follows closely with 84/100. Both cameras are mirrorless and were released in 2021, with the Sony a1 having a higher launch price of $6499 compared to the Canon EOS R3’s $5999.

The Canon EOS R3 stands out due to its larger size (150 x 143 x 87mm) and heavier weight (1015g), which may appeal to those who prefer a more substantial feel. On the other hand, the Sony a1 offers a more compact design (129 x 97 x 81mm) and lighter weight (737g), making it easier to carry and handle for extended periods.

While both cameras excel in their respective areas, the Sony a1’s higher score reflects its overall better performance, making it the top choice for those seeking a high-quality, compact mirrorless camera. The Canon EOS R3, however, remains a strong contender for those who appreciate a more robust build.

Canon EOS R3 vs Sony a1 Overview and Optics

The Sony a1 takes the lead in our optics comparison with a score of 89/100, while the Canon EOS R3 trails behind with a score of 84/100. Both cameras share some common specifications, including a full-frame CMOS sensor, 30 fps shooting speed, and image stabilization. Additionally, they both utilize their respective company’s lens mounts: Canon RF for the EOS R3 and Sony FE for the a1.

The Sony a1 outperforms the Canon EOS R3 in several aspects. With an impressive 50.1-megapixel resolution, the a1 captures more detail and offers higher image quality than the 24-megapixel EOS R3. The a1 also boasts a higher DXOMARK sensor score of 98, compared to the EOS R3’s 96. This difference reflects the a1’s superior image quality, dynamic range, and low-light performance.

Canon EOS R3 vs Sony a1 Video Performance

The Canon EOS R3 outperforms the Sony a1 in video capabilities, scoring 96 out of 100 compared to the Sony a1’s score of 86. Both cameras share some common specifications, such as a maximum video frame rate of 120fps. However, there are key differences that set them apart.

The Canon EOS R3 offers a maximum video resolution of 6K with dimensions of 6000 x 3164, providing excellent detail and quality in video recording. Additionally, the EOS R3 has built-in time-lapse functionality, making it convenient for users who want to capture stunning time-lapse sequences without requiring additional equipment or software.

On the other hand, the Sony a1 boasts an impressive maximum video resolution of 8K with dimensions of 7680 x 4320. This higher resolution allows for even greater detail and clarity in videos. However, the a1 does not have built-in time-lapse functionality, which may limit its appeal for some users.

Despite the higher video resolution in the Sony a1, the Canon EOS R3’s overall video performance is superior, as reflected in its higher video score. The built-in time-lapse functionality in the EOS R3 is a significant advantage and contributes to its higher score. The Sony a1, although offering greater video resolution, may not be as versatile for users who require time-lapse capabilities.

Therefore, the Canon EOS R3 is the better choice for users who prioritize video performance and versatility, while the Sony a1 is more suitable for those who value higher video resolution but can forego built-in time-lapse functionality.
