In 2009, official White House photographer Pete Souza
made history when he created the first presidential portrait ever created with a digital camera (a Canon EOS 5D Mark II).
This time around, Souza used a Canon EOS 5D Mark III
and an EF 85mm f/1.2L USM lens
set to f/7.1, 1/125 second, ISO 200 for the president's second term official portrait
