Sigma 28-45mm F1.8 DG DN Art Lens for Mirrorless Cameras, Sony E-Mount, Support Entire Zoom Range

The Sigma 28-45mm F1.8 DG DN Art for Sony E-mount is a full-frame zoom lens that delivers prime level image quality with the flexibility of a fast standard zoom. Covering a highly usable 28 to 45 mm range with a constant f/1.8 aperture, it is built for hybrid creators who move between still photography and video on the same shoot.

With advanced optics, weather resistant construction and a high response linear autofocus motor, this Art line lens is tuned for demanding professional work. Internal zoom and focus keep the overall length stable for gimbal rigs, while the close focusing design and smooth bokeh make it a strong choice for portraits, events, commercial work and run and gun productions.

The Sigma 28-45mm F1.8 DG DN Art is described as the first full frame zoom lens to offer a constant f/1.8 aperture, bringing prime like speed into a versatile zoom range. Full frame coverage, an 82 mm filter thread and Sony E-mount support make it a natural fit for modern mirrorless bodies used in both stills and video production.

Problem

Many creators are forced to carry multiple fast primes to handle low light, shallow depth of field and different framing needs. Traditional zoom lenses often sacrifice maximum aperture, bokeh quality or focus breathing control, and their extending barrels can upset gimbal balance during dynamic moves.

• Needing to swap lenses when moving between wide, normal and tight framing.
• Zooms that are not fast enough for low light handheld work.
• Lens breathing and changing length that complicate video and gimbal use.

Solution

This Art series zoom is designed as a single lens answer for many full frame Sony E users. The constant f/1.8 aperture supports low light shooting at any focal length, while the internal zoom and focusing design keep the lens length stable. Sigma combines special glass elements, modern coatings and a high speed linear actuator motor to give a lens that behaves like a prime in terms of clarity and rendering, while remaining a flexible zoom for real world productions.

Benefits

• Low light flexibility: Shoot handheld at f/1.8 across the full zoom range.
• Hybrid stills and video use: Suppressed focus breathing and quiet AF support cinematic moves.
• Reduced lens swaps: Cover wide to standard views with one fast zoom on the camera.
• Field ready build: Dust and splash resistant body with protective front element coatings.

Applications

• Handheld event and wedding coverage in low available light venues.
• Gimbal based commercial and social content production with stable balance.
• Hybrid photo and video storytelling where fast setup changes are required.

Why Choose This Lens

• A unique full frame zoom that combines a constant f/1.8 aperture, internal zoom, close focus performance and an Art series optical design, providing a single lens solution for many professional Sony E mount workflows.
