Product Description

Amazon.com Product Description

The addition of a lens hood can help prevent flares--those circles of light that can accompany images where a strong light source is just outside the fame. These type of lens flares occur when indirect light rays pass through the front lens elements but don't make it all the way through to the image sensor. Canon's EW-73B Lens Hood is designed for the Canon EF-S 17-85 f/4-5.6 IS USM SLR Lens.

Product Description

Lens hoods are designed to prevent unwanted stray light from entering the lens. They do this by extending and shading the end of the lens and since the end of the lens is extended, you also achieve the added benefit of some extra protection from accidental impact.

This lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area because of its "petal" shape. This dedicated lens hood is specifically designed to match the exact focal length of the lens it was designed for.

4.0 out of 5 stars Pros and Cons, May 10, 2006

This review is from: Canon EW-73B Lens Hood For 17-85mm f/4-5.6 IS EF-S and 18-135mm f/3.5-5.6 IS Lenses (Electronics)

Pros:
- Reduces flare and ghosting when shooting in bright light.
- Helps protect your lens from dirt and scratches.
- Somewhat protects the lens in case of a fall. Better to break the hood than the front element.
- Makes you look more like you know what you are doing and helps to keep others from carelessly walking in front of you.

Cons:
- Will increase lens movement in windy situations, kind of like a sail on a boat.
- Takes up more room in your bag, even when reversed they still add to the diameter of the lens.
- People take more notice of you, will help to blow your cover if you are trying to keep a low profile.

This review is from: Canon EW-73B Lens Hood For 17-85mm f/4-5.6 IS EF-S and 18-135mm f/3.5-5.6 IS Lenses (Electronics)

I bought this lens hood to go with my 18-135mm kit lens that came with my 60d. at the time of purchase it was less than $20 dollars. the generic brands are usually under $10 dollars but with my past experience with generic lens hoods i wanted to try a canon lens hood. it was basically half of the regular price so i decided to buy it. i liked this lens hood a lot because it fit nice on my lens hood and i didn't have to force anything. it was a perfect fit and slipped on easily. i also liked that when you are not using it you can flip it inwards some generic lens hoods do not have this feature so i believe that this alone was worth the extra price.

when the hood is reversed on the lens, it blocks the zoom ring tremendously when at 17mm's. it's not the end of the world, but you're probably better off storing this in a bag, and not on the lens itself when not in use.
