Definitely something to consider. Different cameras & strobes have different capabilities.
My strobes (ys110) have 12 steps - they go from a GN of 22 down to a GN of 2. I never use them at the lowest power setting. I also tend to shoot at ISO 80.
The Inon-s also have 11 or 12 steps, but each step is 1/2 stop. I see that the YS-110 appears to have 1/2 stops on the low end and full stops on the bright end. But if I'm reading it right, probably does go 1-2 stops further down.
I would love to shoot at ISO 80 or 100, but the Olympus mirrorless (at least the one I have) cannot go below ISO 200.
