Webcam exposure won't go down past 50?

Hi,

We are attempting to use a 120-degree webcam vs the normal 60-degree webcam for vision tracking the gear lift as we want to see as wide of an angle as possible. The problem is the 120-degree Webcam does not allow the exposure to go below 50 on our Raspberry Pi 3 whereas the 60-degree webcam allowed us to go down to 1. We are using v4l2-ctl to set the exposure and brightness.

Is there something else I can try to set the exposure or is using v4l2 the only real way to do it?

Thanks a bunch in advance!
