This is the Yongnuo YN 685 which is probably one of their best value speedlights.
I got it when I was on holiday in Hong Kong and really wish I had purchased more of them. These are somewhat unique as they have both a Yongnuo RF 603 and 622 trigger inside them. Considering that I already have a few 603 triggers, I’m able to fire this flash off without having to worry about getting more receivers. If you are looking to get some speedlights, I definitely recommend getting a few of these and a 622 transceiver.
