What lens should I use for wedding photography?

Most wedding pros carry three lenses: a fast 35mm and 85mm prime for ceremony and portraits, plus a 24–70mm f/2.8 zoom for the reception. The Sigma 35mm f/1.4 DG DN and Tamron 70–180mm f/2.8 are the value picks; the Sony G Master 24–70 f/2.8 II is the no-compromise option.
