Nikon SB-28 fires only at the second frame

[Oki_]

Hello camera trappers,

I use Canon 40D camera with Nikon SB-24 flash and I connect them with Canon TTL cable, which means I have no "wake-up" function. So the first frame is always black. As suggested here, one of the options is to somehow make a custom cable to also transmit half-press signal. But a wireless system is more tempting for me. Did somebody tested cross-system compatibility of YONGNUO RF-603 II transceivers? More specifically, a device for Canon as a transmitter and for Nikon as a receiver. According to specifications, it is also transferring the half-press signal, so I can not see why it should not work together, but I would rather have it tested before buying. Thank you.

The Yongnuo works well with a Canon TX and a Nikon RX.
