The Canon EOS R6 Mark II wins the comparison with a score of 78/100, while the Canon EOS 90D scores 67/100. Both cameras share common specifications such as being released in 2019 and 2022, respectively, and having similar camera sizes. The R6 Mark II is a mirrorless camera, which contributes to its lighter weight of 588g compared to the 90D’s DSLR design and 701g weight.

The R6 Mark II’s higher score signifies its superior performance and features. Its mirrorless design offers advantages such as a smaller size and lighter weight. However, the EOS 90D has a lower launch price of $1199, making it more affordable than the R6 Mark II, which is priced at $2499.

Taking these factors into account, the Canon EOS R6 Mark II is the better camera due to its higher score, indicating better overall performance and features. The Canon EOS 90D, while not as advanced, offers a more budget-friendly option for those seeking a quality camera at a lower price point.

Canon EOS 90D vs EOS R6 Mark II Overview and Optics

The Canon EOS R6 Mark II outperforms the Canon EOS 90D in optics with a score of 83/100 compared to the 90D’s 62/100. Both cameras share some common specifications, such as having a CMOS sensor type and offering compatibility with Canon lenses through their respective lens mounts – the 90D with Canon EF/EF-S and the R6 Mark II with Canon RF.

The R6 Mark II excels in several aspects. It has a faster shooting speed of 40 compared to the 90D’s 10, allowing for more efficient and rapid capture of images. The R6 Mark II also boasts a more advanced processor, the Digic X, which contributes to its superior performance. Its full-frame sensor size and higher DXOMARK score of 91 indicate better image quality and low-light performance. Additionally, the R6 Mark II features image stabilization, providing an advantage in reducing camera shake and improving image sharpness.

Despite having a lower overall score, the Canon EOS 90D still has its strengths. It offers a higher megapixel count of 33 compared to the R6 Mark II’s 24, allowing for greater detail and resolution in images. This may be appealing to those who prioritize image resolution for large prints or heavy cropping.

Considering these factors, the Canon EOS R6 Mark II is the superior option in terms of optics, with its faster shooting speed, better processor, larger sensor size, and image stabilization. However, the Canon EOS 90D may be a viable option for those who prioritize higher resolution images due to its greater megapixel count.

Canon EOS 90D vs EOS R6 Mark II Video Performance

The Canon EOS 90D emerges as the winner in video capabilities with a score of 91/100, while the Canon EOS R6 Mark II scores 83/100. Both cameras share common specifications, such as 4K maximum video resolution and maximum video dimensions of 3840 x 2160. Additionally, both cameras have built-in time-lapse functionality.

The EOS 90D surpasses the EOS R6 Mark II in video performance due to its higher maximum video frame rate of 120fps, which is double the 60fps offered by the EOS R6 Mark II. This higher frame rate enables the EOS 90D to produce smoother and more detailed slow-motion footage, giving it an advantage for videographers who prioritize this feature.

However, the EOS R6 Mark II still has its merits despite its lower score. Its video capabilities are still impressive, and it shares the same 4K video resolution and time-lapse functionality as the EOS 90D. This makes it a suitable choice for videographers who may not require the higher frame rate offered by the EOS 90D.

Taking all factors into account, the Canon EOS 90D proves to be the superior choice for video capabilities due to its higher video score and maximum frame rate. The EOS R6 Mark II, while not as high-performing as the EOS 90D, remains a viable option for those who prioritize other features or have a preference for its design and functionality.
