The short film “Leica – The Hunt” caused a lot of trouble for the German camera maker to the point that the Chinese government banned the word “Leica” from social media. As several LeicaRumors readers already noted (see this and this discussions) the iconic photo titled “Tank Man” was shot with a Nikon camera. The German magazine Der Spiegel reports that all four photographers that captured the events in Tiananmen Square – Jeff Widener (AP), Charlie Cole (Newsweek), Stuart Franklin (Magnum) and Arthur Tsang (Reuters) were all using Nikon cameras:

Franklin’s photos were smuggled out of China by a French student inside a box of tea.
