SIGMA 28-70mm F2.8 DG DN | Contemporary L-mount

The SIGMA 28-70mm F2.8 DG DN | Contemporary reinvents the standard zoom for mirrorless cameras by combining exceptional optical performance, a constant F2.8 aperture and a light and compact lens body. The design of the 28-70mm F2.8 DG DN | Contemporary is inspired by 24-70mm F2.8 DG DN | Art in existence, but with a focal length range starting at 28mm, which makes the lens body significantly smaller and lighter while still maintaining superb optical performance.

It is the smallest and lightest lens in its class. Faithful to the founding concept of the Contemporary range, which consists in maintaining an optimal balance between optical performance and lens size, this new lens offers professional quality results with a small size, ideal for a walk in all freedom.

In addition to focusing on portability, SIGMA optical engineers have developed a new combination of coatings and structural elements that make this standard zoom well balanced for use in a wide range of shooting conditions. In addition, the latest production and manufacturing techniques have been used to ensure exceptional build quality.

The 28-70mm F2.8 DG DN | Contemporary expands the SIGMA range for hybrid systems with another large aperture, fast and efficient zoom, offering a more compact alternative to the current 24-70mm F2.8 DG DN | Art.

Designed based on SIGMA's Art line, with the same optical performance without compromise

The optical design of the SIGMA 28-70mm F2.8 DG DN | Contemporary is inspired by 24-70mm F2.8 DG DN | Art, renowned for its exceptional optical performance over its entire focal length range. Faithful to the basic concept of the Contemporary range, the 28-70mm F2.8 DG DN | Contemporary was developed to offer the right balance between performance and portability. For this reason, this standard large aperture zoom offers exceptional image quality that rivals Art range lenses, and also sufficient brightness for everyday use. Using state-of-the-art technology, the 28-70mm F2.8 DG DN | Contemporary features an advanced optical design that includes three aspherical lenses, two FLD elements and two SLD glass elements. Although it uses less elements in total than the 24-70mm F2.8 DG DN | Artful, its design enables full correction of axial chromatic aberration and sagittal coma aberration, which cannot be corrected directly in the camera, allowing users to create evenly sharp images from center to center. at the edges of the photo. In addition to its anti-flare design, the use of a "Super Multi Layer" multilayer treatment and an NPC (Nano Porous Coating) coating allows good control of reflections for high contrast results under counter conditions. -day. The lens also features a water and oil repellent coating on the front lens.

In short, the SIGMA 28-70mm F2.8 DG DN | Contemporary incorporates all the optical characteristics required of a standard wide aperture zoom, which are essential for photographing a wide variety of subjects under a wide range of shooting conditions.

A compact and lightweight lens, ideal for everyday use

The fact that the angle of view is slightly smaller than the 24-70mm F2.8 DG DN | Art has enabled a significant reduction in the size of the 28-70mm F2.8 DG DN | Contemporary. In order to accommodate the development concept of the Contemporary line, which balances performance and portability, this new lens features a simpler construction, dust and splash resistant, and smaller switches. This makes it the smallest and lightest lens in its class *.

This new lens has only one lightweight element for focusing, which keeps the AF device down to its smallest size, combined with a quiet and fast stepper motor, it allows for responsive autofocus. and silent.

The 28-70mm F2.8 DG DN | Contemporary weighs 470g, and when attached to the SIGMA fp, the set weighs 890g. The supreme portability offered by this set which weighs less than a kilo gives photographers great freedom and flexibility to express their creative vision. It's also a perfect combination for filmmakers looking for gear that performs well, is lightweight, easy to handle, and works well with a gimbal stabilizer and other accessories.

The 28-70mm F2.8 DG DN | Contemporary is a standard large-aperture zoom that is light and small enough for free exits. It opens up new photographic possibilities for better and more creative results.

Superb build quality with careful attention to detail, delivering an exceptional user experience

With priority given to optimal portability, the SIGMA 28-70mm F2.8 DG DN | Contemporary is mainly made up of light pieces. Although popular belief is that it is more difficult to ensure the precision of assembly of plastic parts than of metal parts, no compromise has been made to the build quality of the SIGMA 28-70mm F2. 8 DG DN | Contemporary. One reason is that it uses a type of polycarbonate called TSC (Thermally Stable Composite), which has a level of thermal shrinkage comparable to that of aluminum. This helps reduce variations between the thermal shrinkage of metallic and non-metallic parts, ensuring stable performance levels even in an environment with extreme temperature changes. The use of polycarbonate in the construction of the zoom and focus rings can make their operation less pleasant to the touch, but with careful and precise assembly of these parts and proper adjustment of the movement with a lubricant, the rings provide precise action with a touch of exceptional quality.

What allows us to achieve these parts produced with precision and premium aesthetics is the impressive level of manufacturing technology and the rigorous quality control we have at the SIGMA factory in Aizu.

The SIGMA 28-70mm F2.8 DG DN | Contemporary offers a new, quality photographic experience for hybrid camera users who require a standard large aperture zoom. Its exceptional premium construction makes using this lens as thrilling as viewing the incredible images it can produce, it will inspire you to start unleashing your creative potential.
