Excerpt: My HB-32 hood is used with the fairly new Nikon 18-140mm lens. This is mounted on my Nikon D3x which has a setting to automatically frame areas of the image when shadowed by a lens hood or other impediments such as more than ample attached filters. This may be a failing in the lens design or in what I saw as a curiosity from Nikon as a single lens hood being used for various lenses. In any event, it does not perform with Nikon products as a long-time Nikon user expects.
Excerpt: I bought this lens hood to replace one that I lost because the hood fits so loose on the lens that it kept falling off. Unfortunately, the newest lens hood is just as bad. I haven't had that problem with the other Nikkor lense that I own, so maybe the problem is limited to the 18-70 mm DX lens. Nikon could do a much better job on the fit for this hood.
