Taken from the following thread:

The way to do that is to lock the HV20 at whatever aperture you want- yes, it's limited to f1.8 but that's not far off of what the largest aperture the still-cam lenses are delivering- ie- f1.2. f1.4 or f1.8. Using ND filters to control exposure and fixing shutter at 1/48th.
