Canon EOS M6 Mark II vs EOS Rebel T8i / 850D Overview and Optics

The Canon EOS M6 Mark II wins the optics comparison with a score of 62/100, while the Canon EOS Rebel T8i / 850D receives a score of 57/100. Both cameras share several specifications, such as a CMOS sensor, Digic 8 processor, APS-C sensor size, and no image stabilization feature. Additionally, both cameras have the same DXOMARK score for the sensor at 58.

The EOS M6 Mark II outperforms the Rebel T8i in terms of megapixels and shooting speed. With 33 megapixels, it captures more details in images compared to the 24-megapixel Rebel T8i. The M6 Mark II also boasts a faster shooting speed of 14 frames per second (fps) compared to the Rebel T8i’s 7.5 fps. This faster speed allows the M6 Mark II to capture fast-moving subjects more efficiently.

Although the Rebel T8i has a lower score, it does have a better lens mount with the Canon EF/EF-S, which offers a wider range of compatible lenses compared to the M6 Mark II’s Canon EF-M mount. This advantage provides the Rebel T8i with more flexibility in terms of lens choices and creative options.

In conclusion, the Canon EOS M6 Mark II has superior optics performance due to its higher megapixels and faster shooting speed. However, the Canon EOS Rebel T8i / 850D offers more lens compatibility with its EF/EF-S mount, making it a viable option for those who prioritize flexibility in lens choice.
