The Sigma 16-28mm f/2.8 DG DN Contemporary Lens for Sony E is a compact, full-frame ultrawide zoom that delivers a constant f/2.8 aperture across its entire focal range — giving photographers and videographers the speed and versatility to shoot confidently in low-light environments without carrying the bulk of larger zoom lenses.
Engineered with large-diameter aspherical elements, Super Multi-Layer and Nano Porous Coatings, and an internal zoom-and-focus mechanism, this Sigma Contemporary lens suppresses chromatic aberrations, flare, and ghosting while maintaining a fixed physical length — making it an exceptional choice for landscape, travel, and cinematic work on Sony mirrorless systems.
Key features
- Constant f/2.8 Maximum Aperture: Maintains a fast, consistent exposure across the full 16-28mm range, ideal for low-light shooting and achieving pleasing background separation in close-up shots.
- Internal Zoom & Focus Design: The lens dimensions remain fixed throughout the zoom and focus range, ensuring a stable balance point and a non-rotating front element — perfect for videography and filter use.
- Advanced Optical Construction: Two large-diameter aspherical elements combined with low-dispersion glass effectively control spherical aberrations, distortion, and chromatic fringing for sharp, color-accurate images.
- Super Multi-Layer & Nano Porous Coatings: Minimise lens flare and ghosting in challenging high-contrast or backlit scenes, preserving rich contrast and true-to-life color rendering.
- Near-Silent Stepping AF Motor: Delivers fast, precise, and virtually noiseless autofocus — equally beneficial for stills photographers needing quick acquisition and videographers recording on-camera audio.
- Weather-Resistant Build with Brass Bayonet: Durable weather-sealed construction paired with a precision brass mount ensures reliable performance in the field and consistent mounting accuracy on Sony E-mount bodies.

Frequently asked questions
Is the Sigma 16-28mm f/2.8 DG DN compatible with full-frame Sony mirrorless cameras?
Yes, the Sigma 16-28mm f/2.8 DG DN Contemporary is specifically designed for the Sony E mount and covers the full-frame format, making it fully compatible with Sony Alpha full-frame mirrorless cameras such as the A7 and A9 series.
Does the lens maintain a constant physical size when zooming or focusing?
Yes. Thanks to its internal zoom and focus mechanism, the lens barrel length stays fixed throughout the entire zoom range and at all focus distances, which prevents balance shifts during video and allows the front element to remain stationary for use with screw-in filters on the 72mm thread.
How does the Sigma 16-28mm f/2.8 DG DN handle flare and ghosting in bright conditions?
Sigma has applied both Super Multi-Layer and Nano Porous Coatings to the lens elements, which work together to reduce internal reflections, flare, and ghosting when shooting into strong or direct light sources, helping maintain contrast and accurate color rendering.
