The Arca Compendium was way to narrow for me, as Joe mentioned already, great from 55mm and up.
The Lee wide angle hood is a great solution. It works on the Rod 28mm Schneider 35mm, 43mm, and Rod 40mm. All of these lenses expect the Rod 40mm take a 72mm wide angle adapter ring from Lee (Schneider assumes physical CF installed). The 40mm Rod is 67mm.
You can even use the wide angle hood with one filter slot with no vignetting issues.
I switched to the Lee hood about this time last year, and love it. Built quality is very good only issue to me is how the hood attaches to the wide angle adapter rings. This needs to be a locking screw not the pressure sensitive push that Lee uses. It's too easy to inadvertently hit the release and the pressure it has is not enough. I devised a way to help keep it locked down in the field that helps a lot by running a thick rubber band around the entire assembly, holding the release in place.
In use with me with rm3di, and most of my Nikon lenses great that it can move between platforms.
