Well, I've finally made progress.
All my attempts to get the Rollei to triger the Nikon SB-R200s were being undertaken with the flash off the camera and using the 'test fire' button. I had found that there was a very obvious delay, press the test button, the Rollei (Master) would fire, next, one of the SB-R200s (Slave) would fire and then next the other SB-R200 (Slave) would fire
. So why would this happen, because the clever person who designed this unit must have considered that if you want to test a 'multi' flash setup it's easier to see each firing separately
With the Rollei on the camera and fired from the camera all works fine in both Manual and iTTL. Full testing has shown that the Rollei will trigger both the SB-R200s and the SB-600 each indavidually set as group A, B and C with the ability to be set each in either Manual or iTTL with their indavidual powers or ECs.
For triggering the SBR-200s for macro work it's also possible to 'turn' of the flash of the camera mounted Rollei unit so as not to have front lighting.
So it's now apparent after a lot of user manual deciphering and testing that my Rollei is fully Nikon CLS compatible which the user manual had 'suggested' it was.
