Pitch of Follow Focus Gear
A 4K lens must anticipated a wide range of productions – including theatrical motion pictures, major television dramas and episodics, commercials, and a diverse range of non-entertainment origination. So what are the performance parameters that collectively define 4K optical performance? The following paper will enumerate these parameters and discuss user expectations.
The newer generation of Cinema EOS lenses came from multiple optical design resources within Canon, such as our EF Lens and Broadcast Lens designs.
A design goal with the Cinema zoom lenses was to achieve an overall optical performance that would equate with the best of contemporary prime lenses over their respective focal lengths. Learn more about how these Cinema zoom lenses maintain their sharpness in a close-up or while zoomed out.
The new generation of Canon Cinema lenses paid high attention to optimizing color reproduction of the lens-camera system, such as how it reproduces skin tones of various ethnicities.
Achieving a high contrast ratio is universally sought by cinematographers and is always a central design goal for the optical designers. Learn about the different designs that help achieve high contrast ratios.
