The Pixel Mago, it's great! I did the update to the latest firmware and now I do not know how this is possible but it is even compatible with my Canon 5D mark II 1 / 8000s! and it works I tested a few shoot 1 / 8000s flash sync was good. (Before the update the box blocked the flash 1 / 200s in ETTL)
Otherwise the function 200mm 20mm it's great, the flash menu are very simple and ergonomic for info and the flash has the ETTL fashion (even on firmware on what I received original)
