Longteng 17-50 2.8 or Canon 24 fixed focus, which image quality is better?

According to my practical experience, my answer must be reliable. First of all, let's talk about the difference between Longteng 17-50 2.8 and Canon 24 fixed focus.

Secondly, the zoom lens is flexible when shooting, which narrows the viewing angle or shooting theme. This is an advantage, but it also has disadvantages. Any zoom will affect the imaging quality, which has been repeatedly demonstrated by photography experts. For example, Longteng 17-50 2.8, when shooting scenery, if you use 17, the picture quality will be better. If the picture quality of 50 terminals is worse than that of 17, the picture quality is poor.

Thirdly, the fixed focus of Longteng 17-50 2.8 is different from that of Canon 24. Longteng 17-50 2.8 is used to shoot landscapes, and Canon 24 is used to shoot portraits and individuals.
