Sigma 28-105mm f/2.8 DG DN Art Lens for Sony E-Mount

The Sigma 28-105mm f/2.8 DG DN Art is a full-frame standard zoom powerhouse designed for Sony E-mount mirrorless cameras, covering an exceptionally versatile 28–105mm range at a constant f/2.8 aperture. From wide-angle landscapes and architecture to portraits and close-up detail shots, this single lens handles it all with Art-series optical precision. A high-speed HLA (High-response Linear Actuator) motor delivers fast, near-silent autofocus, while a 12-blade rounded diaphragm produces beautifully circular bokeh throughout the zoom range.
