I've used kodak's HIE in my OM1. I noticed the halos but not the
dimbles. I'll look closer next chance I get. My only suggestion
regarding a plate is modify one on another camera back and use it for
HIE only. I think that if you cover the plate with a material that
absorbs IR, then the halos could be reduced. There is no factory
solution, sorry.
Have you joined the IR mailing list? The IR FAQ may address this also,
I dunno.
Have you tried putting a polyester filter between the film rails behind
the shutter? Many of the 35mm IR shooters do that, it doesn't effect
the dimple problem but lets you use any lens you like without having to
buy IR filters for each one.
Be seeing you.
