Just got a AF-S 400 2.8 D (non VR) along with trunk and 1.4TC
Problem is there is no hood....
From scanning the Net I think the HK 33 (2Pc) hood is the proper hood.
I also read that almost everyone who has the HK33 complains about it being flimsy and easily broken.
I can't seem to find a list or source for interchange BUT I think the HK 60 from the 600mm will fit and possibly a few others.
Anyone have first hand knowledge of what fits ?
