Perhaps some Zuikophiles among us might be able to help me. I've just taken happy possession of a mint OM-System 50mm f/1.4 lens that unfortunately is missing its lens hood. A check on eBay shows a number of listings for a hard rubber clamp-on hood for the 50/1.4, 50/1.8, and 35/2.8. I was ready to buy when I noticed a couple vendors selling a metal hood for a similar set of lenses. Now I'm confused as to which hood is the "correct" one for my lens? In case it matters, my lens is a late-production model with serial number > 1.1 million.
Any help would be most appreciated!
