This lens hood 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 protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles.

User Reviews about Opteka 58mm Screw Mount Flower Petal Shaped Lens Hood with Lock

This hood caught your eye because of the very cheap price, and frankly looks quite professional in the photos. It functions as it should. The material it's made of seems brittle. The lock ring cracked on both hoods on their second use. -- A cheap hood is exactly what you're getting....

I 'm as much at fault for purchasing this lens hood as the manufacturer is for selling it. It's a cheap knockoff of the Canon slip notch lens hood. Spend the extra cash on the Canon. Don't bother kidding yourself and spending the money on the Opteka. I even read the reviews and thought, it can't be that bad and the price was great!. You get what you pay for. On the three Canon lenses I have, I can only screw this cover on about 1/8 of the way, and 9/10 it's on cross threaded. I'm afraid of damaging the threads on my lens. It's not worth the cost of shipping to return it so it will collect dust in a corner somewhere until it gets tossed out with the trash. Think quality and longevity, not price!! -- Don't waste your money

This hood does a fabulous job as a protective device and as a shade for lighting issues across the lens.
I got my Canon EOS Rebel XSI as a gift and it came with a great 18-55mm lens. The hood is actually in the way
for vertical and standard distant flash shots. This is no fault of the hood. It should probably be used
on a longer lens. -- re-check your purpose.

This lens hood was not easy to mount on the lens and because it's plastic the screw threads could be damaged. -- Lens hood
