This
lens features an angle of view from 31.5 degrees to 8.1 degrees (equivalent
in focal length from 76.5mm to 306mm in the 35mm format)
and offers 4X zoom coverage at the telephoto range. The DA 50mm-200mm
features a responsive "Quick-Shift Focus System" that
allows photographers to instantly switch the focus
mode from auto to manual with a slight twist of the
focus ring. Coupled with a simple, functional design and the elimination
of an aperture ring, this mechanism considerably improves operability.
The lens also incorporates an Extra-low Dispersion (ED) glass lens element
and two aspherical lens elements for true-to-life image reproduction.
