Canon 100-400mm IS II Camouflage Neoprene Lens Cover - Realtree AP Snow Pattern Protective Sleeve for Outdoor Wildlife Photography & Hunting

I contemplated buying a camouflage cover for a couple years. I am a wildlife photographer, and I have noticed many birds have been frightened as I lifted up my camera. I hope this cover will really help, as I have only used it once since I installed it. I found it very easy to install but I will probably have to modify it so I can use the switches on the lens. The plastic windows will need to be cut out a little. I believe the company did the best they could because of all the moving parts on the lens. The piece that goes on the telephoto cylinder is put on with velcro, and has to be taken off when you want to go less than 400mm. This is a hassle, but I think this is the only way they could make it. I believe this sleeve comes in 8 separate pieces to cover the whole lens. The only thing I wasn't happy with, is the price. It is quite pricey, but I wouldn't care to try and make one. I do recommend buying this for that expensive lens. It will really protect your lens and help one to get a better shot of a close birds.
