Test footage with hacked Panasonic GH1 and a vintage JCPenney lens. The lens is a 28mm, f2.8. Aperture was set to 5.6, shutter speed 50, ISO 640. I'm really happy with the video this captured.
Music is William Tell Overture, performed by the United States Marine Band. 'Cause what else are you going to use with fireworks? ;)
