Have spent quite some time finding this hood for my FA*300/4.5 lens, but unfortunately it doesn't fit my lens
Seems there are two versions of FA*300/4.5, the earlier one has three teeth on the lens to clip on its matching hood, while the later version has four teeth. Mine is the earlier version while the hood I got is for the later version.
Tried to do some DIY (by adding some extra teeth on the lens at proper position to match the hood), but just noticed that not only the teeth locations don't match, the thickness doesn't match the hood either. The existing teeth on my lens are much thicker than the one on the later newer version (confirmed by another forum member: Lance B, who has the later FA*300/4.5).
After all the hustle, I decide to let this one go, and will continue to search for another one.
I bought the hood new from Japan, spent about $120 shipped to Singapore. Now I'm willing to let it go for $100 which including air shipping to anywhere around the world. The hood still looks like new except some sign of use on the internal teeth.
If you have an FA*300/4.5 w/o a hood, and if it happens to be the newer version (with four teeth on the lens to match a hood, this will be the one for you.
If interested, please let me know. Thanks and Happy Holidays!
