I usually do not use my flash much on my D700 cause it's so good with higher ISOs but see that I may need one for my new OM-D. I have a syn cord SC28 and my Nikon Flash SB800, but don't want to fry or de-warrant my new Olympus OM-D! Wondering if I should purchase the new flash Olympus FL600,- may be worth it. I usually use my Lumiquest softbox II on the flash, and as an amateur, that works for me on the D700. I do some macro photography as well, and a flash would come in handy. Any suggestions?
