This telephoto lens modestly lessens the sense of perspective and provides a soft out-of-focus (bokeh) effect.
This telephoto lens modestly lessens the sense of perspective and provides a soft out-of-focus (bokeh) effect. Two extraordinary-low dispersion glass lenses are used for effectively correcting chromatic aberration and spherical aberration. A ghostless coating is applied for effectively eliminating reflections on the inner surface of the lens for providing sharp images with high contrast. Also, an inner focus is used for focal point adjustment for improved focusing speed by autofocus operation. This also provides a comfortable operating sensation since the lens length does not change while focusing.
