B&H's deal of the day today is a Bolt VM-160 macro ring light. I have no idea if this is any good or how well it would work with my E-M5 and M.Zuiko 60mm/2.8 lens. I know that I'd need a 46-49mm step up ring, but I have no experience with Bolt flashes (this looks like a newer model that I can only find online at B&H). It does seem to be brighter than other cheap ring lights, but I don't know. Could anyone else comment on whether I should get this?
