"Mirror" lenses refer to systems comprised of reflecting mirrors with lenses, a combination that allows telephotos to be lighter and more compact than conventional lenses. The effect on the image is ring blur,great for portrait work. The beauty is heightened even more when lighting is effectively used in shooting, resulting in photographs with overwhelming emotive power.
The use of rear-insertion type filters enables rapid secure filter changes. A rugged ZEN barrel finish helps withstand hard outdoor use.
