DJ,
I didn't write down the specs as I was capturing, lazy me.
But the lens is a 16-100mm, and I'm pretty sure it was taken at f2.3.
The Gstar-ex was set at maximum intergration, 128x senseup.
If you want to learn more about the camera, and because they can explain it all so much better then me, click here.
