I had the opportunity with two other Photogs to play around with a couple of Kino Flos'.
This is Jonas Olson, one of the photogs, lit with two 4' 4-bank kino flos really close on each side. We also had a Profoto B1 on the background.
Canon 5Ds with the Sigma 50/1.4 ART at F1.8
Very nice, really tempted by that sigma when i go back to Nikon.
