Abstract
The main purpose of this paper is to introduce a high speed zoom lens for photography. The lens operates with a full field angle that encompasses more than 86 degrees and the corner illumination is more than 60 percent at the wide end. In addition, the paper provides guidance on how to effectively use an aspheric surface in the first lens group consisting of an NPNPP (negative, positive, negative, positive, and positive). This treatment includes distortion considerations. Useful design solutions using an aspheric surface are introduced along with assessment of the resulting designs. Finally, a strategy to correct field curvature in this zoom lens is shown with an example.
