According to State of the Art, it was a one-off super-pimped Littman 45 Single:
a unique 4×5 rangefinder built on the chassis of a Polaroid 110 that has been completely reengineered to permit both focusing and parallax-corrected viewing through a single window. Translation? It’s sort of a Leica on steroids
Sweet, if a little over-egged with an exterior described as ‘a sort of retro-futuristic homage to the early 20th-century skyscraper’. There’s no word on how much it cost, but apparently Brad Pitt’s a serious amateur photographer. About the only thing I have in common with him.
