Tamron Raises the Bar with the New 12-20mm f/2.8 Ultra-Wide Zoom
Tamron has officially unveiled the 12-20mm F/2.8 Di III (Model A084), a groundbreaking ultra-wide zoom lens for Sony E and Nikon Z full-frame mirrorless cameras. Designed from the ground up, the new lens could become one of the most exciting third-party lens releases of the year.

With an impressive 12mm starting focal length, the new lens offers an incredibly expansive field of view, making it ideal for:
- Landscape photography
- Astrophotography

- Video and content creation
The lens zooms to 20mm while maintaining a constant f/2.8 aperture, giving photographers and filmmakers excellent low-light performance and consistent exposure throughout the zoom range.
A Completely New Design
According to Tamron, the 12-20mm f/2.8 was developed with a new design philosophy focused on delivering flagship-level optical performance.
The lens features:
- 17 elements in 12 groups
- Multiple special and aspherical elements to minimize distortion and chromatic aberration
- A 12-blade circular diaphragm for beautiful sunstars and smooth rendering
- Tamron’s fast and quiet VXD linear autofocus motor
- Moisture-resistant construction and fluorine coating for outdoor use
Despite its impressive specifications, the lens remains remarkably compact, weighing approximately 570g (20.2 oz) for the Sony version and 585g (20.6 oz) for the Nikon version.
