LensCoat® Sigma 50-100mm f1.8 DC HSM Art

I was worried about scratches on my lens body during shoots, but this cover fits snugly and hasn't slipped at all. The cutouts for the switches and zoom ring line up perfectly.

Finally got around to covering my workhorse lens and the protection it adds against dings is exactly what I needed for resale peace of mind. Fits snugly over the barrel and the texture gives a better grip when I'm shooting handheld.

The cutouts for the zoom ring and focus window line up perfectly, so I can still shoot without ever taking the cover off. It's already saved the barrel from a scrape against a fence post, and the resale value staying intact is a nice bonus.
