He brought along with him the Panasonic GH-4 and the Leica Nocticron 42,5mm F1.2, the first F1.2 lens for the Micro Four Thirds system.
Shot at wide open, F1.2
It was a brief encounter, I did not shoot enough to make any meaningful comments. However, I will be seeing Shaun again soon and I will rob the lens off him and shoot for at least a few hours, and you will see a blog entry full of F1.2 photographs soon. I will make sure that happens.
