This is the second photoshoot I did using my Youngnuo Flash with my Canon 600D and my second camera was Sony A58 with a telephoto lens. One of the main reasons I get this flash was to try the High Speed Sync function aka overpowering the sun light. The best place to battle with the sun light is Israel. The HHS gives you the ability to freeze motion and I love doing that with water splashes. I am happy with the flash because it is a great affordable choice with lots of capabilities.
