I'm a complete noob when it comes to lighting, other than trying the clip-on flashes that came with my E-PL3 and E-M5, deciding that they're pretty much useless, and tossing them back in the box. I'm thinking that I'd like some supplemental lighting for macro with my E-M5 and Oly 60mm. There's a major (indoor) flower show around here in the next few weeks. I'd like to try some shots, but the lighting is always pretty poor. Would a cheap ring "flash" (which is more likely to mean an always-on LED light than a true flash) be a waste of money? If not, is there anything I should be aware of when choosing one? If you think it's not worth the money, what would you recommend for a first "starter" flash? If there's something relatively inexpensive that would be useful for indoor shots as well as macro, that would be great.
