Sigma has announced a ‘Mount Conversion Service’ for any of its recent ‘Global Vision’ lenses – a paid-for service designed to reduce the uncertainty of changing camera systems. The company says it will charge between $ 80 and $ 250, plus shipping costs, depending on the specific lens. The Global Vision range currently includes seven lenses – from the huge 120-30mm F2.8 DG OS Sport for full-frame DSLRs, down to the 19mm F2.8 DN Art for Micro Four Thirds. The company has also extended the warranties on all new products to four years.
