LensCoat® Sigma 20mm f/1.4 DG HSM Art

Took it out for a shoot this weekend and the cover hugs the lens perfectly, no sagging or peeling around the edges. Those scrapes and bumps it absorbs are exactly what I was worried about with a lens this price.

The adhesive backing is holding up way better than I expected, and the fit around the barrel is snug enough that it doesn’t shift when I’m swapping lenses in a hurry. My lens has already survived a few scrapes against a metal fence post, so this cover’s doing its job.

The cutouts for the focus and zoom rings align perfectly, so I don't lose any grip or functionality. It's snug but not impossible to install, and the added peace of mind against scratches is well worth the price.
