LensCoat® Sigma 180mm Macro f2.8 EX DG OS HSM

The adhesive backing was super easy to peel and align, and the cover fits snugly enough that it doesn't shift during handheld shots. It’s already saved my lens from a scrape against a rock on a low-angle bug hunt.

The cutouts line up perfectly with the Sigma's switches and focus ring, so I can adjust settings without peeling the cover off. It's snug enough that I don't worry about it slipping during a hike, and the extra padding has already saved my lens from a few scrapes against rocks.

Wasn't sure a neoprene sleeve was worth it until I dragged my 180mm macro through wet brush on a mushroom shoot. It soaked up the damp and left the barrel dry, and the cutouts for the switches line up perfectly. Barely adds any weight too.
