A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide excellent correction for chromatic aberration during close-up photography. "Super Multi Layer Coating" of this lens minimises the occurrence of flare and ghosting. The floating focus system provides extremely high optical performance from infinity to 1:1 Macro. It's the ideal lens for all close-up work as well as for landscapes and portraits.
