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 EF 100mm f/2.8 Macro USM.Customer reviews
Well, my Macro Lens needs it!!

It's too $$$$ for a little black plastic, but I need it for my lens.
Overpriced, but genuine Canon build

Should have come with the lens, but then, the lens would simply have had a higher price, right?
Working good) 
by .. Kai-yuan Shih (Tallahassee, USA)
Working good but ugly looking, no indicator for assembling, really bad surface material (scratch easily)
Useful, but expensive by .. L. Lim (SF Bay Area)
In addition to shading the lens from glare and preventing lens flare in your photos, a lens hood can also help protect the front element of your lens without degrading image quality (like a cheap UV filter, for example). When using on board or hot shoe flash, it may end up shading your subject from the flash.
After seeing the lens hood that came with my 24-105L, and comparing it to the one on my Tamron, I decided to go ahead, sacrifice a few lunches out, and get Canon hoods for my two other lenses. Sure, they're overpriced, but the 3rd party ones are overpriced as well even at half this price on eBay, and at least I know this one fits well.
I removed one star for the price. Otherwise it's perfect.
