Canon 6D2 with EF 85mm f/1.8 lens at f/2. Lit with Flashpoint 360TTL in Godox S-7 Beauty Dish/Octabox
I was having a bit of a problem with the bright ambient light. Even at its lowest setting, I was just barely sneaking through exposure wise since I wanted to shoot at f/2 - the maximum shutter speed of the 6D2 is only 1/4000 second. I missed the 1/8000 of my 7D2. I have the problem solved now: using ISO 50, a 2-stop ND filter and an extra diffusion sock over the light will tone down both the flash power and the exposure for the ambient light allowing me some latitude in my exposure choice...
