Perhaps an alternative, maybe a firmware update can give you the control you want. Note though, chances are good such an act violates your warranty.

@DigiVisionMedia The camera already allows you to set manually parameters like aperture, shutter speed and so on (though those options are buried in submenus you have to navigate with a small joystick, which conveniently discourages any advanced usage). The problem is, the CMOS is too sensitive for daylight, and if you force a low shutter speed then the iris will automatically close to a tiny hole, blurring the image because of diffraction. The only way around it would be a filter, i.e. a piece of dark glass on top of the lens. They have taken good care to make it impossible to adjust one.

There's no ND filters?
