NEEWER PB019 Camera Rain Cover XL Large Waterproof Raincoat Protective Cover for Canon Sony Nikon Fujifilm DSLR Camera & Lenses up to 800 mm Double-Sided Camouflage Green Nylon

I have an expensive camera and an expensive telephoto lens. I don't need them to become damaged. While I haven't needed to use it yet, I can tell that it will provide protection from the elements. I witnessed a friend using this same item successfully. THAT told me I needed it. While he continued to take photos, I had my camera in a plastic bag. Tacky.

While it's clearly made for something bigger than my 350mm, it absolutely does work with smaller lenses, just with a lot of material left over. This really isn't a disadvantage if you're concerned about rain, since you can easily pull it well past the front of the lens and have the camera totally protected if you get a sudden downpour. It does make things more bulky, but for wildlife photography, I try to settle into a small area and minimize movement anyway.I would recommend using it with a lens hood to help keep the objective end clear. You might even consider some nonslip tape or similar around the edge of the hood to help keep the cover in place if you're using it handheld, as moving around in woods or brush does tend to shift it from time to time.

La funda es muy amplia por lo que sirve para grandes objetivos, muy fácil de poner y quitar. La he utilizado en la lluvia y en la nieve y es perfecta

Nice cover in case you deal with heavy rain, for the price? Absolutely amazing. Fits sony 600mm f4 perfectly.

I like it easy to use and lightweight accessory
