The black Hydrophobia Rain Cover 300-600 V2.0 from Think Tank is a sophisticated cover that protects your pro DSLR from moisture, wind, dust and dirt and permits you to shoot under adverse conditions. It's over-sized and accommodates lenses from 300mm f/2.8 up to a 600mm f/4 with an optional Hydrophobia eyepiece attached. A 600mm lens extension sleeve is included for use with a 600mm f/4 or 800mm f/5.6 lens. Its over-sized design permits horizontal or vertical use and can be accessed by its left or right sleeves. Moreover, it can be easily used when your DSLR is tripod or monopod mounted.
The beauty of this item is that it can be attached while the camera is assembled and, in addition, permits you to change batteries or memory cards without having to remove the cover. There's also a lens hood cover that protects the front of the lens. The clear back window of the Hydrophobia allows full access to the camera's LCD screen.
It should be noted that you do not have to remove your camera's strap in order to use the Hydrophobia. Nor do you have to tweak the cover by trimming it.
The Hydrophobia connects to your lens hood by its hook and loop strap, manufactured to be non-slip. Optional Hydrophobia camera eyepieces are required to provide you with a clear view of your viewfinder through the cover. This rain cover comes with a cleverly designed built-in eyepiece pocket that is used to store the Hydrophobia eyepiece while the cover is packed away. Or, use it to hold your camera's eyecup while using the Hydrophobia's eyepiece.
For additional protection from the elements, an eyepiece flap is provided to shield the eyepiece from rain, sand or other potentially interfering contaminants. A lens hood is also provided and can be stored in its own supplied pocket located on top of the cover or it can be completely removed. The Hydrophobia comes with its own mesh carrying bag and is backed by a lifetime warranty against manufacturer's defects.
