What lens is suitable for Canon 750d to shoot people?

Choosing a lens is nothing more than looking at the money you pay and the effect you expect.

The simplest is of course the famous iron-ass spittoon, Canon EF.

50 mm

F/ 1.8

STM, opening the aperture to 1.8 is a bit exaggerated, and opening it to 2.8 is basically no problem.

Advanced point can consider EF.

85 mm

F/ 1.8, which is worse than L, is lighter in color and prone to purple edges. Of course, the advantage is that it is cheap, and the new one is more than 2000.

For this entry-level SLR, the L-class portrait head is not suitable. It is better to go directly to a white rabbit, the portrait is also good-looking, and you can also take a long shot.
