Photos Taken with This Lens


  • Utilizing know-how and the latest design technology accumulated through the past developments, it corrects the aberration thoroughly and achieves high resolution and astonishing rendering performance even near the edge of the image.
  • Achieves both high resolution and beautiful bokeh effect. High level of resolution on the focus point while bokeh in front and behind the point of focus is carefully maintained to have soft rendering. Aberrations including sagittal coma flare and color distortion that affect the image quality are thoroughly corrected. From open aperture, high-definition rendering without blur is achieved. Moreover, by ensuring vignetting at the minimum and preventing color blur around the front and back of the focus point, it also achieves natural bokeh.
  • The molded glass aspherical lens elements provide excellent correction to sagittal coma flare. It is perfect for astronomical photography and shooting of illumination because of the reduced blur on the point light sources near the edge of the image. It also creates an attractive bokeh in portraits and indoor shooting.
  • For axial chromatic aberration correction SLD (Special Low Dispersion) glass elements are incorporated, ensuring high image quality throughout the entire focusing range. The lens achieves sharp and high contrast image rendering.
  • Designed to minimize flare and ghosting.
  • Minimized distortion.
  • Minimum focusing distance of 40cm.
  • Hyper Sonic Motor ensures High AF Speed.
  • Incorporating Rounded 9-blade Diaphragm creates an attractive blur to the out-of-focus areas of the image.

  • This lens incorporates a brass made bayonet mount which has both high accuracy and durability.
