The Blue DSLR Reversible Camera Cover from Zing is a one-piece, wrap-around neoprene cover that stretches over the lens and self-secures without buckles, snaps, or zippers. The removable retainer strap clips onto your camera strap and allows the cover to hang out of the way while shooting. The SLR cover is reversible to black. This cover will fit smaller DSLR cameras with a lens up to 4" long. However, select large aperture and zoom lenses with their increased lens diameters, may be a tight fit. When considering lens size compatibility, filters and reverse-stowed lens hoods should be factored in as well.
