Sigma 28-45mm F1.8 DG DN Art Lens
The Sigma 28-45mm F1.8 DG DN | Art makes photographic history as the world’s first zoom lens offering a constant f/1.8 maximum aperture across a wide-angle to standard zoom range on full-frame mirrorless cameras. This achievement represents a major breakthrough in lens design — combining the versatility of a zoom with the low-light capability and background separation previously exclusive to prime lenses.
At f/1.8 throughout the range from 28mm to 45mm, photographers gain an extraordinary creative tool: wide-angle perspectives with the ability to isolate subjects against softly blurred backgrounds, gather light in conditions that would challenge conventional zooms, and maintain creative control over depth of field without carrying multiple prime lenses.
The Art-series optical formula is engineered to the highest standards, with advanced glass types managing the considerable optical challenges inherent in designing a constant f/1.8 zoom. The result is sharpness, contrast, and rendering quality that meets the demands of the most critical professional applications.
The High-response Linear Actuator provides fast, accurate, and near-silent autofocus for both photography and video. The internal zoom mechanism keeps the physical length of the lens constant — an important practical advantage for video shooters. Dust- and splash-resistant weather sealing ensures professional reliability.
Available in Sony E-Mount and L-Mount, the 28-45mm F1.8 DG DN | A is a landmark lens that establishes a new benchmark for wide-angle zoom performance. Available in Bangladesh from Hope Enterprises — official SIGMA distributor.
