Yongnuo thank you!

I did well to wait. Solutions by wire, infrared or were not exciting, and extremely costly radio solutions.
And these little wonders have happened. They walk every time.
I have four flashes (I will recycle two old silver flashes), so I will make an order for two other triggers. My picture practice will find transformed and facilitated, in a qualitative and creative sense.
You understand that I am very satisfied with my purchase, and I heartily recommend. You will not be disappointed.
Amazon was as usual at the top. Delivery deadlines, price.
