Does Canon Guo Xuwei Image have a fixed focus of 85 1.8? Entangled experts to answer which one to choose? I am an image quality document. Which is better?

The color of Guo Xuwei may exceed the level of 85 1.8, and good color is the same feature of Canon L lens (red circle). However, the maximum aperture is only f4, and the blur ability is not as good as 85 1.8. As for sharpness, 85 1.8 is fixed focus. Although the sharpness is not outstanding in similar lenses, it is fixed focus after all, if not top sharpness, at least it is not bad. Guo Xuwei is one of Canon's sharpest zoom lenses. Generally speaking, the sharpness is basically the same, and 85 1.8 is better.

The choice of these two lenses should not be based on image quality. Guo Xuwei is a zoom lens, which is more convenient but more expensive. 85 1.8 prefers a dedicated lens. If it is only used to take portraits, choose 85 1.8. If it has more uses, Guo Xuwei is more suitable.
