The Sigma 28-105 mm f/2.8 DG DN Art is a full-frame, constant f/2.8 zoom built for hybrid shooters who need a single, versatile lens for stills and video. It pairs a broad 28–105 mm range with a fast, constant aperture and a compact, lightweight design that keeps weight under 1 kg, making it ideal for run-and-gun work, events, and travel.

Engineered with Sigma's Art-series optical formula, the lens includes FLD, SLD and aspherical elements, advanced coatings, and a 12-blade diaphragm to deliver high micro-contrast, pleasing bokeh, minimal focus breathing, and reliable AF performance for both photography and cinematic use.

Sigma 28-105mm f/2.8 DG DN Art Overview

The **Sigma 28–105 mm f/2.8 DG DN Art** combines a flexible focal length with a pro-grade constant aperture, engineered for full-frame mirrorless systems. Its optical design, incorporating FLD, SLD and aspherical elements plus multi-layer coatings, aims to maintain high resolution, minimize chromatic aberration, and reduce flare across the zoom range. With internal focusing, an HLA linear actuator, and ergonomic controls like a lockable, de-clickable aperture ring, the lens delivers hybrid-ready performance for photographers and filmmakers.

Problem

Many single-lens solutions force tradeoffs between speed, range, or weight. Photographers often carry multiple lenses to cover wide to short-tele needs or accept slower variable apertures that limit low-light capability. Video shooters face focus breathing and noisy AF systems that undermine focus pulls and on-set audio. The Sigma 28–105 f/2.8 is designed to address these problems in one package.

• Need for low-light capability across a broad range
• Carrying multiple lenses to cover wide through short tele
• Focus breathing and noisy AF limiting video workflows

Solution

The **Sigma 28–105 mm f/2.8 DG DN Art** answers hybrid shooters with a single lens that keeps aperture consistent while extending from a useful wide angle through short tele. It brings advanced optical elements, effective coatings, and a 12-blade diaphragm into a compact, weather-sealed body with features that matter to pro users, including fast HLA AF, de-clickable aperture, and near-macro capability for additional flexibility.

Benefits

• All-in-one Coverage: 28–105 mm replaces multiple lenses for many shoots.
• Low-light Performance: Constant f/2.8 keeps shutter speeds and ISO lower in dim conditions.
• Video-friendly: Minimal focus breathing and de-clickable aperture for smooth exposure control.
• Portable Pro Build: Magnesium mount and under-1kg weight reduce fatigue during long sessions.

Applications

• Event and wedding photography
• Hybrid photo-video shooting
• Travel and documentary work

Why Choose

• Only full-frame 28–105 mm constant f/2.8 zoom that balances range, speed, and weight, making it a practical single-lens kit for professionals and enthusiasts.
