LensCoat® Canon 400 DO IS II

I was worried about adding bulk, but the cover hugs the barrel snugly and the camo pattern genuinely breaks up that big white silhouette. Scraping against branches

Fits my 400 DO like it was made for it—no sagging or bunching. The texture breaks up the outline nicely, and I’ve already saved the lens from a few scrapes in the field.

The cutouts for the focus and IS switches line up perfectly, making adjustments easy without taking the cover off. Fits snugly enough that I don’t worry about it slipping during a hike. One small thing: the material picks up dust more than I’d like.
