According to this blog post over at cinescopophilia, this is a video performance by the artist who will be featured in the first Sony "FS-100" Super 35 demo video. Shot with Canon DSLRs, not the FS-100 itself, but it's a nice song:
From the looks of the BTS pics taken during the low-light parts of the shoot here and here (lit with a 150W Dedolight), I agree with Philip Johnston over at HD Warrior, who said recently of the F3 (same sensor):
"You could produce a drama in street lighting and tell the Gaffer to take a night off"
If, after seeing these pics, you want your own Dedolight to go with the big sensor on your soon-to-be-purchased Sony FS-100 Super 35 NXCAM, you can find one for $372.50 at Adorama.
Sorry Panasonic, but Sony had me at the word "35mm".
I thought that the next step up from my GH2 would be the AF100. Looks like I might have been wrong, my next step up may very well be a Sony. Time to start looking for a Micro 4/3 to E Mount adapter?
