If you look at the two cameras being used at the bottom of the screen....these are not $500-type cameras.
With the lens? I'd take a guess they were in the $3,000 to $4,000 range (as a minimum)....not the type that a regular guy would lug around.
So it begs the question....getting the ten-odd people to stand there and pose.....with the right photographers on hand? Planned ahead of time? I would suggest that.
