Off-Camera RF60 HSS with V6II
I'm trying to use the RF60 high speed sync capability off-camera with a V6II transceiver. All firmware is up to date.
When off-camera, the RF60 needs to be in Slave mode, but when it's in Slave, it won't switch to HSS with the Multi/HSS button (just goes between Multi and my group alias). How do I make this work?
I'm shooting with a Nikon D300. V6II is set to Camera System: Auto (Nikon), Flash System: Auto, and Sync Mode: Normal HSS.
