This lens features a large aperture of F2.8 for enabling a natural out-of-focus (bokeh) effect for backgrounds and representations with a three-dimensional feel.
This lens features a large aperture of F2.8 for enabling a natural out-of-focus (bokeh) effect for backgrounds and representations with a three-dimensional feel. This provides delineation performance for landscape photos and portraits. High-refraction low-dispersion glass, extraordinary-low dispersion glass, and other components are used to minimize color blurring and allow sharp imaging performance with high contrast and high resolution. An inner focus system is used for keeping stable, superior imaging performance from the infinity end to the minimum shooting distance, and closeup shooting up to a minimum of 1.2m is possible. A large hood with a PL filter operation window is included for enabling accurate operation of a circular polarizing filter while checking the results through the viewfinder.
