im so sick of looking at reviews everything is so expensive now and im just getting more confused. i need a wide lens for my D850 before my trip to Glacier in two weeks and i keep going back and forth on what to grab. i found a used Nikon 14-24mm f/2.8 for 650 but then people say the Tamron 15-30mm G2 is actually better because of the stabilization. my budget is strictly 700 bucks so i cant go higher. the nikon is legendary but that tamron seems newer and maybe sharper? i just dont want to regret buying something this old. which one would you actually pick for mountain shots?
