send a note to trappy, he'll tell ya, i think. i had it but never bought it then closed the window....... they have it in sheets, cheap. cut to fit like between the lens and layer lens part,, or case and lens
sorry, cannot understad your questionthat's interesting seeing the light sensor shifting like that. is the center weighted sensor part enabled?
the go pro has a light sensor you can turn on or off.... little box with a dot in the middle. was wondering if that is turned on or off......
as the film goes, esp towards the end the light sensor shows it shifting as your yawing,,,,,,
