You are only allowed Samsung or Panasonic cameras in, in case you upset the sponsors.
Not really. But probably the next goodwill sapping doctrine that will be issued.
Personally I wouldn't bother taking a camera. Sky plus it, keep the newspapers. Enjoy the experience when you are there. Don't shoot me down in flames, just a humble opinion.
Except all the cameras in the pool itself are 1Dxs...
