For a wildlife photographer being able to shoot in the elements is vital to get eye-catching shots. You must however protect your equipment. This is why I always keep a camera/lens cover in my bag when I'm out photographing. I personally use a camera/lens cover from Wildlife Watching Supplies, made in Britain with fine quality Proofed Polycotton in camouflage colour on the outside and uniform olive-green water-proof nylon on the other. The end is elasticated so that it fits snugly on the lens hood covering the whole of the lens, at the front there is a drawstring to cover the camera's LCD screen.
I've used this camera/lens cover for a couple of months now and have been constantly impressed by it. Shorty after I got it I was in Ireland for a week So when the inescapable rain came, instead of staying indoors I went out to test it. I spent around an hour wandering around the countryside getting completely soaked. When I got back inside however the lens beneath the cover was bone-dry. The same couldn't be said for me. I noticed that rather than being absorbed, the rain slides off the cover, but a constant soaking can get into the polycotton. This is no trouble though as it dries surprisingly quickly and doesn't get through the waterproof nylon beneath.
Not only does the cover protect your camera/lens from the elements it also camouflages it and breaks up the outline helping disguise the camera.
The only downside to this product is that it reduces control over the zoom. If you use a prime lens however this will be no problem, I for one use a zoom lens for the versatility it gives.
The camera/lens cover by Wildlife Watching Supplies is a must have for all photographers, it folds up small so won't take up much space in your bag, but most importantly it keeps your equipment safe from the elements.
