Canon EOS 90D vs EOS Rebel T8i / 850D Overview and Optics

The Canon EOS 90D emerges as the winner in optics with a score of 62/100, while the Canon EOS Rebel T8i / 850D scores 57/100. Both cameras have their strengths and weaknesses, which we will discuss in detail.

Firstly, the common specifications between the two cameras include the CMOS sensor type, Digic 8 processor, DXOMARK sensor score of 58, APS-C sensor size, Canon EF/EF-S lens mount, and the lack of image stabilization. These similarities ensure that both cameras deliver quality images and share compatibility with a wide range of Canon lenses.

The EOS 90D outperforms the Rebel T8i in two key areas: megapixels and shooting speed. Boasting 33 megapixels, the 90D captures more detail in images, making it suitable for large prints and cropping without losing quality. Additionally, its shooting speed of 10 frames per second (fps) enables photographers to capture fast-moving subjects with ease, making it an ideal choice for sports and wildlife photography.

On the other hand, the Rebel T8i has a lower megapixel count of 24, which is still sufficient for most casual and enthusiast photographers. Its shooting speed of 7.5 fps, while slower than the 90D, is still adequate for capturing most subjects, except for extremely fast action shots.

In conclusion, the Canon EOS 90D is the superior camera in terms of optics due to its higher megapixel count and faster shooting speed. However, the EOS Rebel T8i / 850D remains a viable option for those who do not require the extra resolution and speed, while still benefiting from the shared specifications between the two cameras.
