The Sigma 28-105mm F2.8 DG DN Art lens for Sony E-Mount is a versatile full-frame zoom that pushes boundaries with a constant f/2.8 aperture throughout the zoom range. Whether you’re shooting wide landscapes, mid-telephoto portraits, or event coverage, this lens keeps light intake steady, allowing you to maintain depth control and low-light performance without swapping lenses. Its optical design includes FLD, SLD, and multiple aspherical elements to suppress chromatic aberration, distortion, and to deliver sharp details across the frame—even at the edges.
 
Built for professionals, it features a robust metal build with weather sealing, a linear motor autofocus system for speed and precision, and a lockable aperture ring with click and de-click options for flexibility between photo and video. Despite its complex optical design, the lens stays under 1 kg, making it surprisingly portable for what it offers. If you want one lens that covers a broad focal range while maintaining image quality, fast aperture, and rugged build, this is an exceptional choice for Sony E users.
