This flash/strobe is absolutely wonderful. The speed is phenomenal. It keeps up with high sync mode very very well. I’m a big fan of the feature where you can the light on at 3 different intensities. Really helps to setup your shot when you’re shooting in darkness.
The battery last for friggin ever. I haven’t counted but I know for sure I can get several hundred shots before I lose 1 of 4 battery icons.
Highly recommend this light. But don’t buy it here. But it on Adorama.com. Way cheaper!
