Introducing the Sigma 28-70mm F2.8 DG DN Contemporary (Sony E)

The Sigma 28-70mm F2.8 DG DN Contemporary (Sony E) is a versatile wide-angle zoom lens, characterized by its constant maximum aperture of F2.8. The design is suitable for challenging lighting conditions while offering increased control over depth of field.

Lighter and more compact than similar 24-70mm lenses, its optical design incorporates two FLD and two SLD low-dispersion elements, as well as three aspherical elements that reduce a variety of aberrations to achieve high levels of sharpness, clarity, and improved color accuracy. It features only a single lightweight focusing element, allowing the AF system to be kept to its smallest possible size.

This optical design is paired with a quiet, fast stepper motor, enabling responsive and near-silent autofocus performance. It’s an ideal combination for filmmakers seeking a high-performance, lightweight, and easy-to-handle camera system that works well with a gimbal or other accessories.

Each optical surface benefits from Super Multi-Layer and Nano Porous coatings to enhance contrast and color rendering by eliminating reflections and ghosting for optimal light transmission. A water- and oil-repellent coating is also applied to the front lens to resist smudges and droplets.

Its weatherproof design allows it to work in harsh environmental conditions, and a rounded nine-blade diaphragm contributes to a pleasing bokeh quality when using larger apertures.
