Helps to reduce stray light which can cause flare.
Use of specifically engineered Nikon lens hoods is highly recommended.
In less-than-ideal lighting conditions, the performance difference can be substantial.
Flower-Type bayonet lens hood provided with select NIKKOR lenses.
By reducing the amount of non-essential light falling onto the front lens element, lenses can better achieve their optimum optical performance, producing more saturated images.
HB-50 Bayonet Lens Hood 8 8
Bayonet lock tabs flimsey I own a nikon D700 and Have recently purchased the 28-300 nikkor G AF S lens which came with the HB-50 hood. While in a DSLR case (which will accomadate a 70-200 VRII G f2.8 lens and hood) with the hood in the stored or backward position the hood became dislodged while extracting the camera from the case. Which caused the "bayonet locking tabs" to break. This happened so easily that I wasn't even aware of it till I couldn't attach the hood at all. I think that at the price one pays for genuine Nikon lenses we should get a superior product, which this just isn't! December 16, 2010
Poor fit Fit is too loose--hood continually chatters away. Out of a half dozen Nikon lenses with hoods, this is the only one that doesn't fit properly. March 4, 2013
loose hood Ditto to all the above reviews! Lost my hood as well! While my camera was on my shoulder, I always kept my hand on the hood because it becoming detached so easily! Any solutions? March 12, 2012
Ditto Add me to the list of disappointed. You know how expensive it will be to replace, and the Super Glue jobs aren't sturdy. You find yourself walking backwards, or cradling your lens like a baby. So, What do you do? Call in Red Green, and Duck Tape that baby to the lens barrel. And how about if the lens cap that comes with a wide angle lens fits over a thin filter? January 19, 2012
Bad hood for a $1K lens! I also have the 28-300 lens which I bought recently for an Orlando Holiday. On the 2nd day the hood broke-off! I also own the 18-105 and the 70-300 lenses and the hoods for those cheaper lenses are so much better. Its a pity that Nikon decided to save a few bucks on a cheap hood to go with actually a very good expensive lens. Guys, please come up with something more sturdy. April 29, 2011
