Watching the FIFA world cup I see there are a lot of cameras behind the gates net. MOst of them of course using wide angle lenses .
how do the trigger them , achieve focus control ?
are they linked to other cameras directly( manually trigered by the photographer?
there are no to many if you think the huge coverage this event has
how those fortunate to have their cameras there how do they get access to this( application, or a lot of $$$$$ payed ?
