Hello! I'm shooting my first wedding in two weeks and I'd love some advice on gear. I currently have a 50mm 1.8, a Tamron 17-28 2.8, and a Sigma 150-600 5-6.3. I obviously have a significant gap between 50-150mm that I would like to fill-- most pressingly, for the wedding, but I would use a lens in that range for concerts, events and sports as well. Does anyone have recommendations for a somewhat affordable lens that fills much of that gap and would be versatile for all that I shoot? I've been looking into the Tamron 70-180 2.8, does anyone use that or have opinions on it? I'm open to other recommendations, too. For the wedding, if I were to get a lens that goes up to the 180-200 range, would it benefit me at all to bring my 150-600? It's bulky, and I can't imagine needing any focal length over 200, but if there could be any good use for it, I'd rather bring it than regret leaving it at home. Any other wedding tips and advice would be much appreciated as well!
