Question

which lens we needed for the street photography ???​

Answer 1

Explanation:

Canon EF 50 mm f/1.8 STM.

Nikon 50 mm f1. 8G.

Canon EF 50 mm f1. 2L USM.

Canon EF 135 mm f/2L USM.

Sigma 35 mm F1. 4 ART DG HSM

Answer 2

Most people use somewhere between 24mm and 50mm. You could use a 35mm lens on my full-frame DSLR, which means you can get in closer to the subject and get more involved in the scene, which comes across in the photograph.
