Product Description

Hoods are one of the most important accessories for each lens you own. A lens hood provides multiple functions: it shades the lens from stray light, improving your contrast and image quality; in inclement weather, it can assist in keeping moisture or wind-blown debris off the lens; and it protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles.This hood is compatible with Canon EF 70-200mm f/2.8L IS USM lens.For a complete compatibility list please refer to the original manufacturer's web site.

Amazon.com Product Description
Lens hoods are primarily designed to prevent unwanted stray light from entering by extending and shading the end of the lens, ensuring no problems with vignetting or motor functions. Additionally, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. Lens hoods match the specific focal length of the lens it was designed for.

This lens hood fits the following Canon lens:

• EF 70 to 200mm f2.8L IS USM

Customer Reviews

Improves contrast and image quality while offering some protection
Hoods offer several benefits to the photographer. Primarily the hood shades the lens from stray light that may result in an unwanted discoloration or hazing of the image, or the appearance of lens flare. Shading your lens helps improve contrast and image quality. A hood is not required to eliminate these problems, as any item used to shade the lens will provide the same protection from stray light. The hood is convenient in that it is built to offer protection while ensuring that it will not inadvertently find its way into your image.

Photographers often state the protective abilities of a hood as a reason to have one. This hood being a solid petal shapped three and three quarters inch long offers some protection from keeping moisture and wind blown debris off the from lens element. There is nothing more irritating than reviewing your images to find dust spots or other flaws. When in place, the hood can protect the lens from impacting solid objects. Replacing a damaged hood is usually cheaper than repairing or replacing an expensive L lens.

This hood is manufactured for the Canon EF 70-200mm f/2.8L IS lens and normally comes included with the lens when sold new. There is no need to buy one as Amazon often suggests.

Since the hood is wider than the lens; it can easily be stored attached in a reverse position. This doesn't add to the length of the lens, but does make it wider by about an inch. An inch may not seem like a lot, but in a tightly packed camera bag, it is huge. Fortunately Canon provides a storage case with the lens that can be used in addition to your camera bag.

While the protective benefits exist, they are secondary and limited. I find the impact the hood has on my image quality to be the more convincing reason to use a hood. Considering the impact on image quality and the low cost as compared to my other camera equipment (except for a lens case), purchasing a hood is money well spent.

PROS:
Improves contrast and image quality
Offers limited protection to the lens

CONS:
Takes up more space in your camera bag to store with the lens

Canon Quality! Great protection!
I ordered this to replace my hood. It shattered when the lens and camera were dropped. Lens had to go in for repair but I am happy to say that all the lens elements were fine and the body of the lens didn't show any damage. I know the hood is supposed to keep stray light under control but I would say it saved my glass this time around. If your lens doesn't have a hood, get one!

Great Replacement
I ordered this to replace the one that came with my lens. I've used the heck out of the original one and it is worn out. This new one clicks into place and stays there.
