Amsterdam,
The Netherlands - Cooke Optics Ltd., manufacturer of precision lenses
for the motion picture industry, launched Cooke 5/i prime
lenses, designed for all PL-mounted professional
film and electronic cameras.
A key feature of the 5/i Primes is a revolutionary, dimmable, illuminated focus ring, with two separately toggled scales (cinematographer and assistant), that allow the focus puller to read the scales in low lighting conditions. The aperture stops range from T1.4 to T22. Lenses available are 18, 25, 32, 40, 50, 65, 75, 100, and 135mm.
Cooke 5/i optics offer control of flare, distortion, veiling glare, and spherical aberrations at full aperture. The cam-type focus mechanism allows for smooth focus adjustments, while the modular construction increases ease of maintenance and serviceability. The lenses are color-matched and compatible with the entire Cooke range, including S4/i and the new Panchro by Cooke.
The Cooke 5/i Prime lenses are expected to start shipping in October 2009.
