Sigma 28-70mm f/2.8 DG DN Contemporary Lens for L Mount

The Sigma 28-70mm f/2.8 DG DN | Contemporary is a standard zoom for mirrorless cameras with L-mount. It is designed based on the existing 24-70mm f/2.8 DG DN | Art Lens, but with a focal range starting at 28mm. This lens is a combination of outstanding optical performance, an f/2.8 constant aperture, and a lightweight and compact body. In addition, a combination of coatings and structural elements makes this standard zoom lens well-equipped for use in a wide range of shooting environments. It delivers professional-quality results and is portable enough to take on casual outings.

Versatile Design

The Sigma 28-70mm f/2.8 DG DN | Contemporary Lens offers the right balance of performance and portability delivering outstanding optical performance throughout its zoom range. It combines all of the key optical features required of a large-aperture standard zoom lens, which are essential for photographing a wide variety of subjects in a range of shooting conditions.

Optical Design

The 28-70mm f/2.8 Lens has an advanced optical design that uses three aspherical, two FLD, and two SLD elements. These elements correct axial chromatic aberration and sagittal coma aberration, which cannot be corrected in-camera, resulting in uniformly sharp images from the center to the edges of the frame.

Multiple Coatings

Along with its anti-ghosting design, the lens uses Super Multi-Layer Coating and Nano Porous Coating that further minimizes flare for high-contrast results in backlit conditions. The lens also features a water and oil repellant coating on the outer surface.

Stepping Motor

The Sigma 28-70mm f/2.8 DG DN Lens features just one lightweight focusing element, which keeps the AF unit small. Its quiet and fast stepping motor ensures near-silent autofocus performance. This lens offers an improved photographic experience for mirrorless camera users who require a fast aperture standard zoom lens.

Lightweight Body

The Sigma 28-70mm f/2.8 Lens weighs in at 470g, and when attached to the Sigma fp (sold separately), the entire setup is 890g. This is a perfect combination for filmmakers looking for a high-performance, lightweight, easy-to-handle camera system that works well with a gimbal and other accessories. The lens features simple dust- and splash-proof structure with smaller switches.

Superb Build Quality

This Sigma Contemporary Lens uses TSC (Thermally Stable Composite), a type of polycarbonate that has a comparable level of thermal shrinkage to aluminum. This helps reduce differences between the thermal shrinkage of the metal and non-metal parts, ensuring stable levels of performance even in an environment with extreme temperature changes.
