CMS-XML Definition: Wide-Angle Lens
Wide-Angle Lens Wide-angle lenses help us capture the big picture. They are commonly used for landscape and interior photography, when we want to photograph a large part of the scene and get the elements in a scene in focus.

The shape of the lens spectral curve (especially at the blue and red end of the visual spectrum) works in concert with the spectral characteristic of the image sensor, the RGB spectral separation of the color filter array (CFA), the spectral shape of IR optical filter , and finally, the linear matricing strategy employed by the camera manufacturer to implement the final digital camera system colorimetry – as outlined in Figure 3. 2 Figure 3 Showing the separate determinants of the color reproduction characteristic of a Cine Lens-Camera system
It was Canon’s goal to develop a lens that would ensure constant subjective sharpness within that Middle Zone to the degree possible and to further protect that sharpness over the entire focal range of the lens. This was deemed important to achieve the performance expected of a variable prime lens.
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.
Upon confronting the term Modulation Transfer Function, the question immediately arises as to what is being modulated, what is being transferred, and how does all of this bear upon resolution? It will be shown that these terms help us provide a linkage between the resolution capability of an imaging component and the contribution that component makes to the perceived sharpness seen when we look at the final reproduced image.
