I had the same problem with a Nikon One S1, where both lenses do not seem to open up the iris.
I tried cleaning the contacts on the body and lenses, but to no avail. I also tried cleaning and
blowing the other connections on the camera to see if that might be the problem.
I will be buying a new battery to see if that might be the problem, or otherwise I will be sending
the body and lenses back to Nikon for check up and (if possible) repairs.
