Two Special Low Dispersion (SLD) glass elements are provided for color aberration compensation, to assure high image quality. Optimised for digital SLR cameras It incorporates ''Super Multi Layer Coating'' to reduce the influence of harmful light caused by reflections from the digital image sensor. Excellent correction of aberrations Two SLD elements, one Glass Mold Aspherical plus two Hybrid Aspherical lenses provide excellent correction of various aberrations and a high level of optical performance. Minimum focusing distance of 40cm The lens has a minimum focusing distance of 40cm at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.8. DF (Dual Focus) System This lens incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during autofocusing, and yet provides a large focus ring for easy manual focusing.
