Excerpt: I purchased this lens hood to replace one that was lost a sea in Hawaii. I was very pleased that it was the exact OE replacement for my 17-55 Nikkor, and at a better price than Nikon. It fits, it works and it came from B&H quickly.
Excerpt: Overall, this lens hood is very functional as a lens hood, protects the lens nicely, and reversing it for stowage is convenient. HOWEVER it doesn't lock on the lens very securely and has a tendency, especially when in the reversed storage position, to work loose and fall off. I had to purchase a replacement precisely because this happened and I didn't notice it until it was long gone.
Excerpt: I had this lens hood on my 17-55 mm lens for almost 6 years. I use this lens all the time for work, but while overseas on my honeymoon I walked down some slick steps with camera in hand, slipped and fell and figured my lens (and maybe camera) was probably gone. The lens hood cracked and my camera and lens amazingly still worked. So, not only is this good for reducing flare, but it did protect the lens in this particular instance. I have now purchased a new one.
Excerpt: This is a great product for your Nikon 17-55 f/2.8 lens. It's a very durable plastic lens hood and offers great protection on both top and bottom as well as the sides. It has a locking mechanism so it won't twist off your lens. I bought this one as a replacement should my original hood break.
