Canon EOS R8 vs Sony a7 IV Overview and Optics

The Sony a7 IV outperforms the Canon EOS R8 in optics with a score of 85/100 compared to the R8’s 77/100. Both cameras share several similar specifications, including a CMOS sensor, full-frame sensor size, and compatible lens mounts (Canon RF for the R8 and Sony FE for the a7 IV). However, the Sony a7 IV has some advantages that lead to its higher score.

The Sony a7 IV boasts a higher megapixel count at 33 compared to the Canon EOS R8’s 24. This difference allows the a7 IV to capture more detailed images, making it a better choice for photographers who require high-resolution output. Additionally, the a7 IV’s DXOMARK sensor score is 97, while the R8’s is 94, indicating that the a7 IV’s sensor delivers better overall image quality.
