>>2643539My Nikon 24-70 f/2.4 has literally travelled around the world with me. It's my go to lens for a lot of my work, along with my 85 1.4 and my wide angle.
Very sturdy construction, although you probably wouldn't want to run around in too much of a sandy situation as you'd get a bit of grit into the lens, but it's got a great reputation for a reason.
