Cooke 1.4x Extender for S4i 300mm

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.
