My brother is a photography major and is going to give him a Canon 7D. What kind of lens should he have?

Canon's best reputation is fixed focus in red circle and telephoto in small white. I don't know which one you want to buy. The price of the lens is very different. The concept of "slightly expensive" is vague. I recommend some for you. See for yourself.

The most expensive choice: 16-35(24-70)+70-200/2.8, 85/ 1.4, 135/2 (the latter three can all take portraits, and Xiaobai has more application scope, and the latter two are like poisonous heads).

Cheaper options: 17-55+85/ 1.4 or 70-200/4.
