The Canon EOS R8 takes the lead with a score of 76/100, outperforming the Canon EOS 90D, which scored 67/100. Both cameras were released in different years, with the 90D arriving in 2019 and the R8 in 2023. Despite the difference in release years, they share similarities in their specifications.

Both cameras have the same launch price of $1199, but the R8 boasts a mirrorless design, making it lighter at 461g compared to the 701g DSLR 90D. The R8’s compact size (133 x 86 x 70mm) also gives it an advantage over the bulkier 90D (141 x 105 x 77mm).

However, the 90D has its merits, especially for those who prefer the traditional DSLR experience. Its heftier build may offer a more familiar feel for some photographers.

Taking into account the scores, specifications, and design, the Canon EOS R8 emerges as the superior camera, offering a lightweight and compact solution without compromising on performance. The Canon EOS 90D, while not as highly scored, still holds its ground as a reliable DSLR option.

Canon EOS 90D vs EOS R8 Overview and Optics

The Canon EOS R8 outperforms the Canon EOS 90D in optics, scoring 77/100 compared to the 90D’s 62/100. Both cameras share some common specifications, such as the CMOS sensor type, the absence of image stabilization, and the shooting speed. However, there are key differences that make the EOS R8 the superior choice in terms of optics.

The EOS R8 has a full-frame sensor, while the 90D has an APS-C sensor. The larger sensor size of the R8 contributes to its higher DXOMARK score of 94, compared to the 90D’s score of 58. This means that the R8 delivers better image quality, particularly in low-light conditions. Additionally, the EOS R8 features a more advanced Digic X processor, which further enhances its imaging capabilities.

While the EOS 90D has a higher megapixel count at 33 compared to the R8’s 24, the R8 compensates for this with its impressive 40 shooting speed. This makes the R8 better suited for capturing fast-paced action and sports photography. Furthermore, the EOS R8 is compatible with Canon’s RF lens mount, which offers a wider range of high-quality lenses designed specifically for full-frame mirrorless cameras.

In contrast, the EOS 90D uses the older EF/EF-S lens mount, which may limit its potential for future lens upgrades. However, the 90D’s higher megapixel count may be advantageous for those who prioritize capturing finer details in their images or require larger print sizes.

Considering these factors, the Canon EOS R8 emerges as the better choice for photographers seeking superior optics performance. Its full-frame sensor, advanced processor, and compatibility with the RF lens mount provide significant advantages over the EOS 90D. However, the 90D may still appeal to those who value higher resolution images and are content with the older EF/EF-S lens mount.
