    A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide excellent correction for all types of aberrations and produce an exceptional level of optical performance. Sigma’s super multi-layer lens coating reduces flare and ghosting, and helps create a natural color balance.

    The floating focus system provides extremely high optical performance from infinity to 1:1 Macro.

    A ‘Focus Limiter Switch’ in incorporated on the lens, improving the speed and accuracy of autofocus by limiting the focus range. A screw-in lens hood is included for convenient use of circular polarizing filters.
