Neil A. V. and Mike Bee used a metal one without vignetting. Need
to ask them for specifics. I just know that they managed to get
them in used box at camera store for cheap.
I went to my local used camera stores and looked to see what there
was. I ended up buying a metal lens hood for an Olympus 35mm f/2
lens. It is a wide angle lens hood, so it will not vignette at the
wide zoom setting. It has a 55mm filter thread, so it mounts right
on my filters. (I use the Fuji adapter tube that came with my wide
angle add-on lens.)
I would suggest the you drop by your local camera store and look
through the bin of used parts, if they have one. Most used camera
stores do have a junk bin or a lens hood bin. See what there is
that fits you filters (52mm or 55mm depending on what adapter tube
you bought) and try it out.
Remember that you will need a wide angle hood, or else you will get
vignetting at the wide aend of your zoom.
I hope that this helps,
