Tokina 28-80 ATX (Angenieux design) Hood Issue

I own the same lense and I too searched all over for the web for an original hood without success. I finally ordered a 77mm universal hood from Amazon and it has worked well for me. It dosen't hurt that it gives a little more protecton to the front of the lense. It is also threaded for filters.
