Sigma has announced availability and pricing details for its 60mm f/2.8 DN lens in the US. First revealed at the CP+ Camera and Photo Imaging Show in Japan earlier this year, the 60mm F2.8 is a new focal length in the Sigma lineup for both Micro Four Thirds and Sony E-Mount camera systems. It joins Sigma’s other DN lenses for MILCs: the 19mm F2.8 DN and the 30mm F2.8 DN. Featuring Special Low Dispersion (SLD) glass, which helps minimise axial and transverse chromatic aberration, the Sigma 60mm f/2.8 DN offers a minimum focusing distance of 19.7 inches and a maximum reproduction ratio of 1:7.2. The new 60mm F2.8 DN Art lens will hit shelves mid-May at an estimated street price of $239.
