     Cooke Optics, the premier manufacturer of precision lenses for the motion picture industry, announced that it will unveil 135mm lenses for its 5/i Prime and Panchro lens sets at IBC 2011 on Stand 11.D10. The 135mm focal lengths are the latest eagerly anticipated additions to each set.
     The 135mm for the 5/i set has T1.4 speed and the 5/i’s signature focus ring that illuminates when required, eliminating the need for external lights that affect the shot.
     The Panchro 135mm joins the smaller, lighter weight set at T2.8, and adds further value to this lower-cost lens range that is finding favour on projects including 2nd unit film shoots, dramas and documentaries.
     Both lenses are colour-matched and calibrated to all existing Cooke lenses and feature built-in /i Technology which provides cinematographers, camera operators and post teams with vital metadata including lens setting, focusing distance, aperture and depth-of-field, hyperfocal distance and focal length in both metric and imperial measurements.
     The full range of Cooke 5/i, S4 and Panchro lenses, including the new 5/i 135mm lens and a prototype of the 135mm Panchro lens, will be on display on Stand 11.D10 at IBC 2011.
