The multi-element lens is all about light transmission. As we outlined in our previous papers, skilful management of MTF (Modulation Transfer Function) is an inherent part of contemporary lens design.
So too, management of light transmission through two dozen or more optical elements is an equally complex task.
In that context, two aspects of that transmission system stand out as being of primary importance:
Firstly, the amount of light that emanates from the output optical port of the lens is a measure of the sensitivity (or optical speed) of the lens in question.
Secondly, the shaping of the spectral response of that light in its passage through the many elements comprising the lens system has a direct bearing on the colour gamut reproduction capability of the lens/camera system.
