Nikon HB-8 Hood

This is as expensive as it's hard to find. I guess it's not hard to find if you are willing to pay up for a hood. I have a "for" Nikon hood which is just another way of saying, hey it's is not a genuine Nikon hood but it works, kind of or hopefully. When I bought my used Nikon 20-35, it comes with the or a hood. I thought it's a Nikon hood as it doesn't say non-manufactured like it says with other stuff. Oh well it turns out it's a "for" Nikon hood. It's not tight and quite easily comes off. Imagine you play to be some professional and then the hood comes off, how embarrassing. I wonder if it's because of its used condition or because the nature of it being a twist click on and being plastic. Some of my hoods or shades are metal, threaded or spring loaded threaded and they are pretty secured. Of course there are always some exceptions. I have one hood (HK-2) for the 24mm which is a crazy a-screw-tight-on-the-side type. And the screw broke pretty much right away. Sure I bought it used. Fortunately the vendor gave me a refund. I think the HB-8 hood is almost a necessity for the 20-35 unless you are into ghost and flare. A genuine used HB-8 is selling for almost $30. Ouch!
