This PL-mounted lens with focus scales in feet is part of the Cooke Varotal/i FF series. The Cooke 19-40mm T2.9 Varotal/i FF Zoom Lens removes the compromise associated with zoom lenses. For observational documentary, live broadcast, efficiency, or just style, they offer imaging performance commensurate with prime lenses. Varotal/i extends the photographic possibilities that Cooke offers cinematographers.
