CINEMA EOS LENSES
|
This picturesque metaphor actually captures a reality not often understood. The cine lens is tasked with intercepting a significant amount of three-dimensional scene information in the form of optical wavefronts impinging on the lens faceplate and transforming these into a tiny two -dimensional optical representation that is then projected onto the camera image sensor. In that optical transformation a multiplicity of “footprints” are indelibly stamped on many attributes that collectively describe the image quality of that output optical image.
