The Sony a6600 outperforms the Canon EOS 90D with a score of 75 to 67. Both cameras were released in 2019 and have a similar launch price of around $1200. They share common specifications such as having an APS-C sensor and being suitable for semi-professional photography.

The Sony a6600, a mirrorless camera, is better in terms of size and weight, being smaller at 120 x 67 x 69mm and lighter at 503g. This makes it more portable and easier to handle. On the other hand, the Canon EOS 90D, a DSLR camera, offers advantages in terms of optical viewfinder and handling, especially for those who prefer a more traditional camera experience.

Taking these factors into account, the Sony a6600 is a better choice for those prioritizing portability and weight, while the Canon EOS 90D may be preferable for photographers who value the advantages of a DSLR.

Canon EOS 90D vs Sony a6600 Overview and Optics

The Sony a6600 outperforms the Canon EOS 90D in terms of optics, scoring 76/100 compared to the Canon’s 62/100. Both cameras share several features, including a CMOS sensor, an APS-C sensor size, and similar shooting speeds (10fps for Canon and 11fps for Sony). However, there are key differences that set these cameras apart in the optics department.

The Sony a6600 boasts a higher DXOMARK sensor score of 82, while the Canon EOS 90D has a lower score of 58. This advantage allows the Sony a6600 to produce better image quality, especially in low light conditions. Additionally, the Sony a6600 features in-body image stabilization, which the Canon EOS 90D lacks. This feature helps reduce camera shake and allows for sharper images in handheld situations.

On the other hand, the Canon EOS 90D offers more megapixels at 33, compared to the Sony a6600’s 24.2 megapixels. This difference allows the Canon to capture more detail in images, potentially making it a better choice for photographers who prioritize high-resolution output.

Despite the higher megapixel count, the Canon EOS 90D falls short in other areas, with a lower overall optics score and the absence of image stabilization. The Sony a6600’s higher DXOMARK sensor score and image stabilization make it the superior choice for those seeking better image quality and performance in various shooting conditions. While the Canon EOS 90D may have its advantages in terms of resolution, the Sony a6600 provides a more well-rounded and versatile optics experience.
