The R7 is also more compact (132 x 90 x 92mm) and lighter (612g / 1.35lbs), making it a more portable option for casual photographers.

Taking these factors into account, the Canon EOS R3 is a superior camera for professionals seeking better handling and stability, while the Canon EOS R7 offers a more affordable and portable option for casual users.

Canon EOS R3 vs EOS R7 Overview and Optics

The Canon EOS R3 outperforms the Canon EOS R7 in optics with a score of 84/100 compared to the R7’s 82/100. Both cameras share several specifications, including a CMOS sensor, Digic X processor, Canon RF lens mount, and image stabilization. However, the R3 surpasses the R7 in certain aspects, while the R7 has its advantages as well.

The R3’s superior shooting speed of 30 frames per second (fps) compared to the R7’s 15 fps allows for capturing fast-moving subjects with ease. This feature makes the R3 a better choice for action and sports photography. Additionally, the R3’s full-frame sensor provides better low-light performance and increased dynamic range compared to the R7’s APS-C sensor.

On the other hand, the R7 boasts a higher resolution with 33 megapixels, compared to the R3’s 24 megapixels, resulting in more detailed images. This advantage makes the R7 more suitable for landscape and portrait photography, where high resolution is crucial. Moreover, the R7’s DXOMARK score for the sensor is 97, slightly higher than the R3’s score of 96, indicating a marginally better sensor performance.

Taking these factors into account, the Canon EOS R3 stands out as the winner in terms of optics due to its faster shooting speed and full-frame sensor. However, the Canon EOS R7 is not without its merits, particularly in high-resolution photography. Ultimately, the choice between the two cameras depends on the specific requirements and preferences of the photographer.

Canon EOS R3 vs EOS R7 Video Performance

The Canon EOS R3 outperforms the Canon EOS R7 in video capabilities with a video score of 96/100, compared to the R7’s score of 91/100. Both cameras share some common specifications, such as a maximum video frame rate of 120fps and built-in time-lapse functionality. However, differences in video resolution and dimensions set them apart.

The EOS R3 excels with a maximum video resolution of 6K and dimensions of 6000 x 3164, providing superior image quality and detail compared to the R7. This advantage makes the R3 a more suitable choice for professional videographers and filmmakers who require high-resolution footage.

On the other hand, the EOS R7 has a maximum video resolution of 4K with dimensions of 3840 x 2160. While this is lower than the R3, it is still an excellent choice for many users, particularly those who prioritize a balance between video quality and file size. The 4K resolution is more than sufficient for most applications, such as vlogging, online content creation, and casual videography.

Considering these points, the Canon EOS R3 is the clear winner in terms of video capabilities due to its higher resolution and larger dimensions. This makes it the ideal option for professionals and enthusiasts seeking the best possible video quality. Meanwhile, the Canon EOS R7 remains a strong contender and a more budget-friendly alternative, offering reliable performance for a wide range of users with its 4K capabilities.
