John Schwartzman: Custom Anamorphic Lenses

From American Cinematographer, When Worlds Collide by David E. Williams (July 1998)

Optics engineer Dan Sasaki, who works at Panavision's corporate headquarters located in Woodland Hills, California, modified Schwartzman's E- and C-series anamorphic lenses to focus much closer than they normally would.

"Many American Cinematographer readers probably don't realize that you can't just put any lens on any camera and expect it to work flawlessly at all focus distances and f-stops. Each one has its own sweet spot, and you not only have to know where that spot is, but that you can move it around; it's not set in stone. Richard Mosier, my first A.C., spent three weeks with Dan working on the astigmatizers and the front anamorphasizers on these lenses, optimizing each and every lens for our use. For example, we thought we'd be generally using our 135mm E-series lens at about 8 feet, so why not maximize the performance of the lens at that distance with a stop of T4.5? Dan is a genius with lenses, and he kept us up and running throughout the shoot."
