Which fixed-focus lens does Canon 7D match? Mainly shooting people.

Hello, Canon 7D is a truncated camera. The best lens for fixed-focus portrait shooting is 50/ 1.2, and the cheaper lens is 50/ 1.4. This focal length changes greatly, close to the human eye's perspective. The composition and the distance from the subject are moderate, and the imaging is guaranteed. The focal length of the portrait mirror 85/ 1.2 for the truncated camera is a bit too long.
