PDF CINEMA EOS LENSES
The broadcast lens design group of Canon has serviced the world’s broadcasters, production studios, and mobile production facilities for many decades. ... Canon’s optical design teams spent a considerable time using powerful computer aided simulation tools to explore the possibilities in reconciling very high 4K specifications with a variety of novel design strategies that would collectively contribute to a unique Canon Personality in the new cine zoom lenses.

The curves shown in Figures 4 and 5 yield the anticipated MTF characteristics at one specific spatial frequency – namely, 40 line pairs per millimeter (LP/mm). Given that the optical Nyquist frequency for a 4K lens is twice that – at80LP/mm– the question might be asked: why look at half that defining boundary spatial frequency? Many years of accumulated experiences in cinematography have shown that the most important region of an MTF curve lies in its central region.

Studying how each of these lenses convoluted with the Canon CMOS image sensor and allied Canon CFA helped establish overall color reproduction benchmarks that guided the subsequent exploration of the new Canon cinema lens spectral response. Video processing – in the form of the digital linear matricing system – was also optimized. The judgment of color balance was made by Canon color scientists in concert with invited directors of photography studying the simulated imagery.
