My YN RF602 triggers can wake flashes from sleep with a half-press of my camera's shutter button, which is an extremely useful feature that allows me to use less expensive Canon EZ series flashes instead of the expensive Nikon SB-24/25/26/28 flashes that are always in high demand.
Have there been any recent flash triggers that integrate this ability, or are the RF602s still the only cheap triggers that can do it?
