Anyone tried the little known aftermarket adapter for the HB-29 hood, which is designed to allow the HB-29 to mount onto the non-AF-S 80-200/2.8 D lenses...and tried it specifically with a NON-D 80-200/2.8?
The original lens has a different design than both of the newer D versions, in that the front of the lens rotates and telescopes out via a helicoid while focusing. It's hard to tell from the pictures of the adapter whether or not the adapter would inhibit the telescoping of the lens's front. I'm hoping that the adapter would fit, but I'm not very optimistic, because when I look at the lens, I can't imagine how it would fit properly. The lens has approx 1/8th inch of barrel in front of the clear plastic distance scale window. The adapter would have to seat onto that short barrel front sufficiently well, and then it would also have to allow the frontal element housing (which is inset and slightly smaller in diameter than the outer barrel) to rotate freely during focusing.

Funny that this post came up. I just ordered one of these adapters for my AF 80-200 f2.8 D. The E-Bay seller sent it out today.
I normally use my AF-S 80-200 f2.8, but sometimes I want a smaller and lighter lens without reaching for the slow AF 70-200 f4-5.6 D. The problem is that the AF 80-200 f2.8 D lens hood is terrible. I am placing the adapter on a different lens than yours, but I'll post photos as soon as it arrives.

Okay Guys, here's the opinion you wanted.
The EBay seller was a pretty good guy in terms of quickly sending out the adapter. The adapter seemed pretty decent in quality. There were no machining marks, burrs, or any sort of blemish I could really see or feel. Unfortunately, the machining was not cut correctly so when I went to bayonet the adapter to the lens it was not aligned correctly to have the HB-29 be aligned. The fit from the adapter to the lens was good so that the hood clicked into place nicely without any play. The EBay seller was true to his word about returning his product for a refund.
I did not bother to shoot any photos as I could not get to fit correctly. However, you may want to give it a try yourself if you have a different version of the lens as the seller was good about honoring the refund.
I'll try to get a photo posted of what I mean. I'm out of town and have not mailed it back yet, although the seller already approved the return without hassle.
I mailed the adapter back. He did not offer to let me keep it, nor did I ask to keep it. It did not work for me so I returned it for a refund just like any other retail transaction. It cost almost nothing, so I almost did not bother to take the time to mail it back.
I suppose I could attempt to adjust it/ remachine it, But right now I am busy with family and work. I probably would not waste my time on it since this lens is not my primary 80-200 f2.8 zoom. I may end up buying the latest AF-S 70-200 VRII for my upcoming Alaskan trip.
The concept of this adapter is a good one. However, I feel it would have been better executed if it had been machined out of brass or aluminum. Yes, the cost would probably be double or even triple, but I think it would be worth the cost.
Looks like your hood is basically misaligned due to incorrect rotational positioning of the adapter's threads.
What is the interior diamater of the part that slips over the lens barrel and how far does it slip over? Still trying to figure out if it will fit the original version of the lens and clear the rotating front block.
