The Yongnuo 568EX III is, for the money, an amazing piece of kit. As with any budget kit, there are drawbacks, but if you have $100 in your pocket, not the $600 you would need for a Canon 600EX-RT, then you could do a whole lot worse than Yongnuo.
The Atomos Ninja Flame is one of my favorite pieces of kit! I was using it on a video shoot yesterday and I can tell you now, it is truly amazing. Here's our BudgetProPhoto review!
