LensCoat® Nikon 600 AFS I

Was a bit skeptical about the cost at first, but the neoprene material feels really protective and the cutouts for the tripod foot are perfectly placed. Snug fit that doesn't shift around when I'm hiking to a blind.

The fit on my 600 f4 is snug and the cutouts align perfectly with the controls, so nothing gets blocked. It’s already saved me from a nasty scrape against a rock ledge during a shoot, and the camo pattern does break up the shape nicely.

The fabric is surprisingly tough, and the way it breaks up the lens outline is a huge plus for wildlife photography. Fits my 600 perfectly and feels like it'll take a real beating.
