Sigma 16-28mm f/2.8 DG DN Contemporary Lens (Sony E-Mount)
The Sigma 16-28mm f/2.8 DG DN Contemporary is a high-performance ultrawide zoom that redefines the balance between aperture speed and portability. Designed for full-frame mirrorless systems, this lens provides a versatile range of focal lengths perfect for sprawling landscapes, immersive architecture, and high-end videography. By maintaining a constant f/2.8 aperture in a remarkably lightweight body, it serves as a powerful tool for creators who need professional low-light performance without the bulk of traditional wide-angle zooms.

Optical Excellence & Advanced Coatings
Constant f/2.8 Aperture: Enjoy consistent exposure settings throughout the entire zoom range. The fast aperture is ideal for low-light scenarios and creating a shallow depth of field for unique, wide-angle close-ups.

Complex Glass Arrangement: Featuring two large-diameter aspherical elements and specialized low-dispersion glass, this lens effectively suppresses chromatic aberrations and distortion, delivering edge-to-edge sharpness and accurate color rendering.

Flare & Ghosting Suppression: Sigma’s Super Multi-Layer and Nano Porous Coatings significantly improve contrast, ensuring clear imagery even when shooting in tricky, backlit, or strong lighting conditions.

Rounded Nine-Blade Diaphragm: Produces a smooth, circular bokeh that adds a professional aesthetic to out-of-focus highlights.

Precision Engineering for Video & Stills
Internal Zoom & Focus: Unlike many zooms, this lens does not change length when focal lengths are adjusted. This fixed physical size keeps the balance point constant, making it an ideal choice for use on gimbals and drones.

Near-Silent Stepping Motor: The AF system is fast, precise, and quiet, supporting advanced tracking features and ensuring that focus noise won’t ruin your video audio.

Weather-Resistant Build: Constructed with a durable brass bayonet and weather-sealing, this lens is built to handle the rigors of travel and outdoor photography.

72mm Filter Thread: The front element is designed to accept standard screw-in filters, allowing for easy use of polarizers and ND filters without the need for bulky specialized holders.

Condition & Functional Notes
This lens remains optically excellent and fully functional, with a specific note regarding the exterior:

Cosmetic Note: The rubber zoom ring grip is starting to become loose. This does not affect the optical performance or the accuracy of the zoom mechanism, but it is a noted sign of use for the buyer.

Mechanical Status: The autofocus is responsive, the internal glass is clean, and the mounting flange remains rigid and accurate.
