Although he also used Leica cameras sometimes, Capa used Zeiss Contax 11 cameras on D Day.
Right!
Capa was a Contax user.
He only used the Leica at his beginnings, his photographs from the spanish civil war were taken with a Leica (the "dying soldier" for example). After that he got himself a Contax (more expensive than a Leica at that time) and gave his Leica equipment to Gerda Taro. He continued using the Contax II and later the Nikon S series, and the Rolleiflex (which he hated). On D-day he used a Contax, as he wrote in his autobiography ("Slightly out of focus"). The day he died in Indochina (1954) he was carrying a Nikon (color) and a Contax (B&W).
