He has a Lomo Fisheye 2. He posted a few days ago about it...here is his camera. I believe it has 1/100 shutter and B.

I bet he is shooting inside at 1/100. With an F8 lens, I can see what it would be dark.

What we dont know is what ISO does he have (100?).

What shutter speed did he use?

Info re his camera that I google'd
