This lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports.  SLD (Special Low Dispersion) glass and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all type of aberrations.  The super multi-layer lens coating reduces flare and ghosting and provides high image quality from the extremely large aperture. 

The lens hood, designed exclusively for this lens, blocks out extraneous light. A 72mm filter can be inserted at the rear of the lens, and a circular polarizing filter can be used in situ thanks to the ingenious internal rotation mechanism.

For the convenience of the photographer, focusing distances and focal lengths can be viewed on the lens` built-in LCD panel.
