The Sigma 28-70mm f/2.8 DG DN Contemporary is a versatile wide-to-portrait zoom lens designed for Sony E-mount full-frame mirrorless cameras. Compact, lightweight, and bright, it delivers exceptional image quality with the flexibility needed for both photography and video. Its constant f/2.8 aperture ensures excellent performance in low light while giving full creative control over depth of field.

Compact Design, Powerful Performance

Smaller and lighter than typical 24-70mm lenses, the 28-70mm f/2.8 DG DN is ideal for travel and handheld shooting. It features an advanced optical design with two FLD and two SLD low-dispersion elements, along with three aspherical elements. These work together to minimize chromatic and spherical aberrations, resulting in sharp, high-contrast, and color-accurate images.

The lens uses a single lightweight focusing element, allowing for a compact autofocus unit. Combined with a fast and quiet stepping motor, it provides smooth, silent, and accurate AF performance—perfect for filmmakers and content creators using gimbals or lightweight rigs.

Exceptional Optical Quality and Coating

Every optical surface is treated with Super Multi-Layer and Nano Porous Coatings, reducing flare and ghosting for clear, color-rich imagery even in challenging lighting. A water- and oil-repellent coating on the front element helps resist smudges and fingerprints, making maintenance easy and reliable.

Designed for Durability

This lens is built to perform in demanding environments. The weather-sealed construction protects against dust and splashes, while a brass bayonet mount ensures precision and durability. Its nine-blade rounded diaphragm produces smooth, natural bokeh, giving portraits and close-ups a professional, artistic look.
