The Canon EOS R5 C outperforms the Canon EOS R3 with a score of 87/100 compared to 84/100. Both cameras share the same mirrorless design and were released within just a few months of each other. However, the R5 C’s lower launch price of $4499 and lighter weight of 770g make it more accessible and portable than the R3, which costs $5999 and weighs 1015g.

The EOS R3 does have a larger size, measuring 150 x 143 x 87mm, providing a more substantial grip for some users. Despite this advantage, the R5 C’s higher score, affordability, and compact size make it the superior option for most photographers.

Canon EOS R3 vs EOS R5 C Overview and Optics

The Canon EOS R5 C wins in the optics comparison with a score of 88/100, while the Canon EOS R3 scores 84/100. Both cameras share several key specifications, including a CMOS sensor, Digic X processor, full-frame sensor size, Canon RF lens mount, and image stabilization.

The R5 C outperforms the R3 in terms of megapixels, boasting 45 compared to the R3’s 24. This significant difference allows the R5 C to produce higher resolution images, which is crucial for photographers who require large prints or heavy cropping. Additionally, the R5 C has a marginally higher DXOMARK score for its sensor, scoring 97 compared to the R3’s 96. This suggests that the R5 C provides slightly better image quality, particularly in terms of dynamic range and low-light performance.

On the other hand, the R3 excels in shooting speed, capable of capturing 30 frames per second compared to the R5 C’s 20. This makes the R3 a more suitable choice for photographers who need to capture fast-moving subjects, such as sports or wildlife.

To conclude, the Canon EOS R5 C offers superior image quality and resolution, making it an excellent choice for those requiring high-resolution images and better low-light performance. However, the Canon EOS R3 provides a faster shooting speed, catering to photographers who need to capture quick action. Ultimately, the choice between these two cameras depends on the specific needs and preferences of the photographer.

Canon EOS R3 vs EOS R5 C Video Performance

The Canon EOS R5 C outperforms the Canon EOS R3 in video capabilities, scoring 100/100 compared to the R3’s 96/100. Both cameras share some common specifications, including a maximum video frame rate of 120fps and built-in time-lapse functionality.

The EOS R5 C excels with its higher maximum video resolution of 8K, compared to the R3’s 6K. Additionally, the R5 C provides larger video dimensions at 8192 x 4320, while the R3 offers 6000 x 3164. These differences result in the R5 C delivering superior video quality and detail, making it the better choice for professional videography.

The EOS R3, despite its lower score, still provides excellent video capabilities. Its 6K resolution and 6000 x 3164 dimensions produce high-quality videos suitable for most applications. However, it falls short when compared to the R5 C’s superior 8K resolution and larger dimensions.

Considering the video capabilities of both cameras, the Canon EOS R5 C stands out as the superior option for videographers seeking the highest resolution and detail. The Canon EOS R3, while still offering impressive video features, is more suited for those who do not require the additional resolution and dimensions provided by the R5 C. Ultimately, the choice between these two cameras depends on the user’s specific needs and preferences in video performance.
