Thank you @bobbyzfx. I don't understand why they make this so confusing. Since I am only using manual mode right now I thought I would try single pin. @jknights The odd thing is that I shot a couple frames with the r2, blue as can be, switched to the xt16 and back to normal color balance. All camera/flash settings the same. I have emailed Adorama and one of the tech guys called this evening, will call him back tomorrow to see if he has a better solution. It's unbelievable how much time I've wasted on this.
