The Canon EOS 6D Mark II takes the lead with a score of 71/100, while the Canon EOS 90D trails behind at 67/100. Both cameras are DSLRs, with the 6D Mark II released in 2017 and the 90D in 2019. They share similarities in size, with the 6D Mark II measuring 144 x 111 x 75mm and the 90D measuring 141 x 105 x 77mm.

The winning 6D Mark II has a lighter weight at 453g, compared to the 90D’s 701g. However, the 90D boasts a lower launch price of $1199, while the 6D Mark II debuted at $2000. Despite its higher score, the 6D Mark II may not be the best choice for budget-conscious photographers.

Taking these factors into account, the Canon EOS 6D Mark II offers a better overall performance, but the Canon EOS 90D provides a more cost-effective option.

Canon EOS 90D vs EOS 6D Mark II Overview and Optics

The Canon EOS 6D Mark II comes out ahead with a score of 69/100 for optics, compared to the Canon EOS 90D’s score of 62/100. Both cameras have several similarities in their specifications, such as having a CMOS sensor type, the absence of image stabilization, and Canon EF lens mounts. However, there are differences that contribute to the 6D Mark II’s higher score.

The Canon EOS 6D Mark II has a full-frame sensor size, which gives it an advantage over the 90D’s APS-C sensor size. This larger sensor size allows for better image quality and low-light performance. Additionally, the 6D Mark II has a higher DXOMARK score for the sensor, reaching 85 compared to the 90D’s score of 58. This higher score indicates better overall sensor performance.

On the other hand, the Canon EOS 90D has a higher megapixel count of 33, compared to the 6D Mark II’s 26.2 megapixels. This higher resolution allows for more detailed images and better cropping flexibility. The 90D also boasts a faster shooting speed of 10 frames per second, compared to the 6D Mark II’s 6.5 frames per second, which is beneficial for capturing fast-moving subjects.

Despite these advantages for the 90D, the Canon EOS 6D Mark II’s superior sensor size and performance make it the better choice for optics. The larger sensor and higher DXOMARK score result in improved image quality and low-light capabilities. Although the 90D has a higher megapixel count and faster shooting speed, these factors are not enough to make up for the 6D Mark II’s overall better optics performance.

Canon EOS 90D vs EOS 6D Mark II Video Performance

The Canon EOS 90D outperforms the Canon EOS 6D Mark II in video capabilities, with a video score of 91/100 compared to the 6D Mark II’s 57/100. Both cameras share some common specifications, such as having built-in time-lapse functionality. However, the 90D excels in various aspects, making it the superior choice for video recording.

The Canon EOS 90D boasts a maximum video resolution of 4K with dimensions of 3840 x 2160, while the 6D Mark II only offers Full HD resolution at 1920 x 1080. This difference in resolution means that the 90D captures significantly more detail in video recordings. Furthermore, the 90D provides a maximum video frame rate of 120fps, allowing for smooth slow-motion footage. The 6D Mark II, on the other hand, has a maximum frame rate of 30fps, limiting its capabilities in capturing fast action or creating slow-motion effects.

Despite its lower score, the Canon EOS 6D Mark II does have some advantages over the 90D. It is a full-frame camera, which means it has a larger sensor size than the 90D’s APS-C sensor. This can result in better low-light performance and shallower depth of field, making it a viable option for certain video applications.

Considering these factors, the Canon EOS 90D emerges as the better option for video capabilities due to its higher resolution, faster frame rate, and higher overall video score. However, the Canon EOS 6D Mark II may still appeal to users who prioritize full-frame sensor benefits, despite its lower video score and limited resolution and frame rate options.
