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.

Customer Reviews

Too expensive!
Canon's pricing on this lens shade reminds me of inkjet printers: they practically give you the printer, then skin you alive with ink costs. Don't get me wrong, the "tulip" shade works fine (although it throws a shadow on imges when you use the pop-up flash), but it should cost a fraction of what they charge. I'd guess they cost less than two bucks to make, if that. It's nothing but formed plastic. I don't like giving Canon a bad review because, otherwise, they make world-class products. So I'd give this lens shade five stars for use, but one star for pricing, an overall 3.

Pros and Cons
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.

reversed
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.
