The SIGMA 28-70mm F2.8 DG DN | Contemporary redefines the standard zoom lens for mirrorless cameras: It combines outstanding optical performance and a continuous aperture of f2.8 with a light and compact body. In terms of design, the 28-70mm F2.8 DG DN | is based Contemporary on the 24-70mm F2.8 DG DN | Art, but with a focal length range from 28mm. This makes the lens housing significantly smaller and lighter, with the same outstanding optical performance. It is the smallest and lightest lens in its class. Overall, this new lens follows the core concept of the Contemporary product line of achieving an optimal balance between optical performance and lens size. It delivers professional quality in such a compact housing that it can be taken with you on any occasion.
