The winner of the tele photo wars is the guy in the middle. The guy between the Canon 500 at the front and the Minolta 600 at the back, with the small narrow white tube. It’s a 1200mm digiscope. He has it mounted on an Olympus m4/3!
The 1200mm digiscope on a micro-4/3rd camera gives him a whopping 2400mm lens. So he works at f/11 with an ISO that oscillates between ISO 1600 and ISO 3200.
