Yes. It's going to be a simple fire / don't fire operation. If that flash on the camera can work with Nikons TTL functionality (i.e. the camera and flash talk to each other to decide how much light the flash should put out) you are NOT going to get this same feature off camera using the Yongnuo transceivers, in other words, what you're going to have is a flash that will fire at the right time but you'll have to set it's strength manually.
