Suppose that your question is posed to me. I guess I could have been more specific in my post. He said he tried with his Auto Iris On or Off. I recommended it not be on auto. There are five (5) other settings that are basically manual iris control. He didn't say which he tried. My recommendation was that he try all of the other 5 non-auto settings.
Question - Rather than putting down other folks replies, do you have a constructive recommendation for the poster who started this sub-thread?
