AH! I kind of foolishly assumed that it was a fixed aperture... This has been very helpful!
I suppose I will just shoot, cross my fingers, hope for the best, and also shoot digital as back-up/kind of b-roll to cut to (it's a music video so I feel I can get away with that...MUAHAHA!)
just one more question:
Do you know if it meters continuously or just when the shutter-release button(? not sure if it's still called that on a movie camera....) is initially pressed?
Thanks Again!
