CINEMA EOS LENSES
|
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. That extensive exploration examined all aspects of lens image quality parameters and image aberrations and distortions in a prolonged search for an aggregate performance that would speak to the urgings of those with whom we had consulted.

This paper will discuss the design criteria established to seek optical image sharpness that would meet the expectations of those seeking to achieve a high performance variable prime lens. Sharpness Criteria for a “Variable Prime” Cine Lens Canon set three specific design targets for the new lenses:

This is a methodology developed in the era of motion picture film cinematography which indicates the amount of color variation within a specific film imaging system, caused by different lens transmittance characteristics. This is a topic too complex to fully examine in this paper . Those interested can learn more from references [1], [2], and [3].
