      The Pictorial Lens

      While it seems both intuitive and obvious that optical companies would pursue the development of ever-sharper and better-corrected photographic lenses—and, in fact, devote considerable resources in terms of money and time to that pursuit—there is one group of end users whose desire was to achieve ex...

      Three Lenses in One

      Before zoom lenses had been developed (the forerunners of which were being developed early in the 20th century) photographers had use of the triple convertible lens.  The first iterations of these were unsymmetrical rapid rectilinear designs:  when used singly, the front and rear groups wo...
