The precision design of the Telephoto + Circular Polarizing Lens (CPL) delivers a 2x optical zoom, allowing you to get twice as close to your subject - while the removable CPL reduces glare and reflections and makes colors look rich and true to life. In addition to bringing your world a little closer, the Telephoto lens provides a shallower depth-of-field allowing the use of selective focus to capture stunning portraits and make your subject stand out distinctly from their backgrounds.
