The ThinkTank Hydrophobia 70-200 is a tough seam-sealed waterproof cover, providing extreme weather protection for any size body DLSR with a lens up to 70-200/f2.8 or similar size attached. An integral camera strap eliminates the need to remove a strap already attached to the camera (this is retained inside the cover by an internal strap). The cover is designed to be quickly attached and detached, so there's no need to remove the lens from the camera, and all the controls are easily accessible once it's in place. n.b. a camera-specific Think Tank Eyepiece is required to attach the cover to camera.
