The ELD (Extraordinary Low Dispersion) and SLD (Special Low Dispersion) glass elements offers exceptional solution to correct color aberrations. Their design incorporates hybrid aspherical and glass mold lens technology, which makes a lightweight and compact construction. To reduce ghost and flare, the manufacturers uses super multi layer lens coating and the front lens rotation can be prevented with the inner focusing system, which is compatible with the supplied petal-type lens hood.
