Take a look at Canon’s gear room at the 2012 Olympics in London. There may be a million dollars worth of equipment in these photographs.
From what I understand, many professional photographers utilize the camera manufacturer’s high-end equipment at sporting events on a temporary basis. This saves them the cost of purchasing the expensive equipment for themselves.
Get a load of those lenses! The bigger ones cost thousands of dollars. These are precision machines. I am not sure if the gear is rented out or if it is supplied gratis for a period of time. These items are not for the photographer on a budget.
I have always liked the appearance of the black-and-white tubes on Canon’s big lenses. They look like cameras that NASA designed – very Space Age.
