What kind of lens is best for street shooting?

First, 35mm, or 28mm. Wide angle is generally the main focal length of shooting streets. For example, the GR of a classic street camera is 28 mm, and the equivalent focal length of most mobile phones is also 28 mm..

In addition, the advantage of wide-angle end is that it can create a deep depth of field, so that the background is not easy to blur. Different from portrait photography, it will deliberately create a shallow depth of field to highlight the subject, while 35mm or 28mm can bring a relatively wide depth of field to record the background even with a large aperture, which will substitute more stories for the shooting theme.
