My macro flash arrived today, straight from Hong Kong within a week. The weather was a bit miserable today so I only found some flies in the cemetery. I am quite pleased. The flash system comes with two flash units that mount on a ring which gets attached to the front of the lens and a trigger that gets attached to the hot shoe of the camera. The flashes are triggered using radio. I am quite happy with it. Let's hope for some better weather with lots of wee beasties.
