I love this flash's convenient mix of power and small size, and the fact it could be triggered and controlled for different settings by the OM Wireless command unit that is sold separately, i think the guide numbers could be conservative because i am having too much power on 1/128 about a meter and a half from the subject when shooting wide open with my Awesome Zuiko 45 mm 1.2 lens, I metered with my sekonic at 200 ISO and 1/200 shutter speed F2.5 about a meter and a half...that is plenty of power and i am coming from SB 800/910 which surprised me, i was expecting mush less . Keep up the great products coming i am into this system.

I don't use flash too often for my work and personal use, but the FL-700WR has been great so far. It's sufficiently powerful for my needs and has done everything I've asked of it thus far. I've used it to photograph people at events and for family photographs. The FL-700WR has worked very well when photographing captive birds and those in the wild. I recently ordered the FC-WR Wireless Flash Commander to further expand the functionality of my Fl-700WR flash. Once it arrives I will be doing flash with still life subjects. It is also great to know that the same weatherproofing on my E-M1X carries over to this flash.
