What lens does Canon 750d choose?

Canon 750d has 18 to 55 lenses. I usually prefer to take portraits and want to add a lens. I suggest choosing a small spittoon, which is cheap and good, and the better one can choose 50/ 1.4. 18- 135, 24- 105 The focus part is duplicated with 18-55. Upgrade 18-55, and you can choose 24- 105 red circle head.

Canon 750D is a C-format SLR camera. Theoretically, Canon's EF and EF-S bayonet lenses can be used.

Because Canon SLR lens group has dozens of models, you don't know your budget, usage and requirements for image quality, so you can't give the lens model directly. But you can give some ideas about choosing a lens, and you can make a reasonable choice according to your own needs.
