"Unlimited wonderful". The new version has a locking ring, faster sync speed and they have finally moved the on off switch to the side. So no more poking at a partially hidden switch with a ballpoint pen. The new version apparently works on similar pin brands like Olympus also (this is the Nikon version). Build quality is pretty much unchanged, but the increased sync speed is good. Previously I rarely managed above 160th on a D7000.
