Cooke S4i T2
Cooke S4 optics offer superb optical and mechanical performance, control of flare, distortion, veiling glare and spherical aberrations at full aperture.
The cam-type focus mechanism allows for smooth focus adjustments. Modular construction increases ease of maintenance and serviceability.
All focal lengths are color balanced, achieving excellent contrast and resolution over the full Super 35 format.
Recently we have added new focal lengths which are making very large set.
