I'd have told her to go and do her nails or something. And pointed out to the men around her that in my opinion, the wide angle and low light ability of the full frame sensor more than makes up for these slight obstacles, and that even if the final product were (very unlikely) played on a display higher res than full hd, most of the viewers wouldnt notice the slightly soft line skipped 1080p anyway. I'd finally remind them that it was a conference setting where we are not filming fast paced car chases or quick pans where rolling shutter becomes an issue.
No one, and i mean no one with any idea about anything would question a man working with a 1DC, -unless they were jealous they didn't get the job that is!
In every situation like this there are 'do-ers' and 'talk-ers'. Usually it's the talkers who outweight the man who is actually doing something.
