Ultra-Wide Full-Frame Zoom Lenses

Tamron has introduced the 12-20mm F2.8 Di III ultra-wide full-frame zoom lens — a new optic available for both Sony E Mount and Nikon Z Mount mirrorless systems.

The 12-20mm F2.8 Di III model represents a significant step in lens design, as it currently holds the title of the widest full-frame zoom lens in Tamron's lineup. The design offers a field of view that begins at an expansive 12mm. The optical construction is engineered to tackle the specific challenges of ultra-wide photography by incorporating specialized elements like an eXpanded Glass Molded Aspherical (XGM) lens and three additional glass-molded elements to ensure sharpness from the center to the far corners of the frame. For astrophotographers and low-light shooters, the fast and constant F2.8 aperture is a critical feature, as it allows for brighter viewfinder imagery and shorter exposure times.
