Chris, does the yongnuo work with wireless triggers? I've since found out that my Nissin di622 doesn't, and it's annoyed me somewhat.
Sorry about the delay Matt. I've only just picked this up (had to take my wife and credit card shopping)
I don't know about wireless triggering as I never use it. But the IR works a treat on the Yongnuo. In fact, something as cheap as this just shouldn't work as well as it does!
Just an added note of caution to the Canon types out there. Check the trigger voltage of any flash you intend to buy. Canon (and many other brands) have a very low trigger voltage and some of the cheap/older flashguns can fry the electronics. Nikon use a big steel girder that comes crashing down on a bit of left-over railway line and can cope with massive trigger voltages.
The day you think you've found perfection is the day you stop looking, then someone else will find it and move in front of you.
