The Cooke 18mm Panchro/i Classic T2.2 Full Frame Prime Lens combines the warm look of a vintage Cooke Speed Panchro with the convenience of the /i Technology lens data capture system. This updated full frame redesign works with both digital cinema and film cameras, features focus scales on both sides marked in feet, and covers full frame image formats. One of several focal lengths available, the 18mm FF prime incorporates a nine-blade iris for cinematic bokeh, and it shares a common 110mm front diameter with the entire line. For optimal performance, the aberration, flare, and distortion correction extends over the entire image area and throughout the T2.2 to T22 aperture range. The Panchro/i Classic FF primes are color-matched with Cooke's S4/i, 5/i, mini S4/i, and Anamorphic/i lenses.
