How to make yourself more professional in photography

Judging from the focal length, your genre is "limited" to some extent. Telefocus is more suitable for shooting close-ups, sketches and other genres, and it is easier to use. As for the standard lens, that is, the medium focal length, you don't have a suitable lens yet. You can look at Canon's 17-55/2.8, 50/ 1.8 or 50/6538. Professional or not depends not on your equipment, equipment is just a tool. The key is to look at the photographer, that is, the person who uses the equipment. I feel that you are in a bottleneck now. You can look at your previous photos to see what genre you mainly focus on, and then look at some related works online, compare them (not contrast equipment), and see how the other person took photos, how they used up, and how they composed pictures, and then do more in practice.

There are many websites and forums in this field, such as Promise, Hummingbird, POCO, Pacific Ocean, New Photography, Oak and so on. And the address is different. Baidu search will find it:)

Wish you success! :)
