The Sony a7 IV outperforms the Canon EOS RP with a score of 84/100, compared to the Canon’s 65/100. Both cameras share common features, such as being mirrorless and having similar dimensions. However, the Sony a7 IV, released in 2021, is a more recent model than the 2019 Canon EOS RP, which could explain its higher score.

The Sony a7 IV excels with its higher resolution, better autofocus system, and improved video capabilities, justifying its higher launch price of $2499. On the other hand, the Canon EOS RP has a lower launch price of $1300, making it a more budget-friendly option. It also has a lighter weight at 440g, compared to the Sony’s 659g, which may appeal to those looking for a more portable camera.

While the Sony a7 IV is the better camera in terms of performance and features, the Canon EOS RP offers a more affordable and lighter option for those on a budget or prioritizing portability.

Canon EOS RP vs Sony a7 IV Overview and Optics

The Sony a7 IV outperforms the Canon EOS RP in optics, scoring 85 out of 100 compared to the Canon’s 67. Both cameras share similar specifications, such as CMOS sensor type, full-frame sensor size, and respective lens mounts (Canon RF for the EOS RP and Sony FE for the a7 IV).

The Sony a7 IV excels with a higher megapixel count of 33, double the shooting speed at 10 frames per second, and a superior DXOMARK sensor score of 97. Additionally, the a7 IV features image stabilization, which the Canon EOS RP lacks. The Bionz XR processor in the Sony a7 IV also contributes to its better performance in optics.

On the other hand, the Canon EOS RP has a lower megapixel count at 26 and a slower shooting speed of 5 frames per second. Its Digic 8 processor and DXOMARK sensor score of 85 are inferior to the Sony a7 IV. The absence of image stabilization in the EOS RP further highlights its disadvantage in the optics comparison.

Despite the lower score, the Canon EOS RP still offers a respectable performance in optics. Its full-frame sensor and Canon RF lens mount provide good image quality and compatibility with a range of Canon lenses. However, the Sony a7 IV clearly surpasses the EOS RP in terms of optics specifications and overall performance.

Considering the significant difference in optics scores and the advantages offered by the Sony a7 IV, it is evident that the a7 IV is the superior choice for photographers seeking better performance in optics. While the Canon EOS RP remains a viable option, the Sony a7 IV outshines it in this comparison.
