Exclusive: Prototype Canon 400mm f/2 legacy lens review

Something you have never seen before - a mysterious legacy prototype / one-off Canon lens from the 1970's / 1980's, with crazy parameters. Huge thanks to cinematographer Joel Honeywell for hiring it to me - check out his website here: http://joelhoneywell.com/
