just before his death, he was concentrating on the "ultimate focus" lens, which makes both near and far objects equally distinct. "just before he died he had worked out a new lens with which he had made spectacular shots. he carried in his wallet a strip of film taken with this lens, of which he was very proud. it was a shot of a face three inches from the lens, filling one-third of the left side of the frame. three feet from the lens, in the center of the foreground, was another face, and then, over a hundred yards away was the rear wall of the studio, showing telephone wires and architectural details. everything was in focus, from three inches to infinity".
