Yongnuo YN568EX-II Master Mode

The Yongnuo YN568EX-II has the ability to control up to 3 groups of remote (slave) speedlites, being Groups A, B & C in either ETTL, Manual or Multi Mode.

SB-900 SU-4 Optical Slave Mode

Nikon SB-900 Speedlight

Like the SB-800, the SB-900 includes a handy SU-4 mode. This allows the SB-900 to be optically triggered by seeing any other flash, even a non CLS flash. Using the SB-900 in SU-4 / Manual mode allows you to control the output just like any studio flash. However, unless my units are faulty Nikon seems to have forgotten the audio beep function to notify you when the SB-900 has completed the recycle and is ready to fire again. I always liked this on the SB-800 and it’s one more backwards step that I hope they will address in a future firmware update. Continue reading
