Cooke 1.4x Extender for S4i 300mm
The Cooke 1.4x Extender for S4i 300mm is an extender for Cooke’s S4i range. Although already the 300mm lens has a great zoom, there may be times you wish to zoom in further for that particular shot. The extender gives you that advantage and allows you to capture the video or image you want that you would have otherwise missed.
The lens the extender is designed for offers 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.
Our Cooke S4/i Prime lenses are supplied with /i Technology that collect detailed lens data for production, VFX and post-production teams and are designed for all PL mounted professional motion picture film and electronic cameras. The /i Technology provides cinematographers and camera operators with vital information on lens setting, focusing distance, aperture and depth-of-field, hyperfocal distance, serial number, owner data, lens type and focal length in both metric and footage measurements, as well as inertial tracking data, shading and distortion data. For zoom lenses, the zoom position is displayed.
Please note: This is only the extender, the S4i lens is not included.
