Don Zeck Lens Cap, fits Canon 200mm f/2.0 USM IS or 300 f/2.8 USM IS or 400mm f/4.0 USM IS DO Lenses
Finally, a practical and effective lens cap to protect your front element from scratches, dust, rain, and other hazards. Many high end Canon@ and Nikon@ lenses come equipped with only a leather or canvas "sock" to cover the lens and lens hood. These "socks" are heavy, bulky, and difficult to install and remove. The o'Don Zeck Lens Cap" features a collapsible handle to facilitate mounting or removal of the cap while the hood is in the shooting position. You can use the cap while the hood is in the stored position. These caps are precision machined from rugged black l/2 nchpolypropylene to exacting tolerances. The cap is held in place by six "O" rings that create a perfect fit. Nothing touches your lens optics and the thick design will protect against damage to your front element. It is a must for safaris, inclement weather, or extreme conditions. Please visit our web site for more
