The Tamron 12-20mm F2.8 lens is an engineering marvel, designed to meet the rigorous demands of professional photographers. With a compact and lightweight build, this lens offers exceptional control features that make it ideal for capturing stunning astrophotography.
Boasting an ultra-wide focal range that starts impressively at 12mm, the 12-20mm F2.8 (Model A084) is tailored for full-frame mirrorless cameras. Unlike typical 14mm or 16mm lenses, the expansive 12mm view delivers an extraordinary sense of scale. As Tamron describes it, and many would concur, this perspective offers a dynamic intensity perfect for capturing everything from grand architectural structures to sweeping landscapes.
The remarkable width of the 12mm view, combined with a bright F2.8 maximum aperture across its zoom range, positions this lens as a game-changer in the realms of astrophotography and interior photography. Tamron proudly touts it as the “new protagonist” for these genres.
The lens’s potential is evident in its sophisticated optical system, which includes an XGM (eXpanded Glass Molded Aspherical) lens element, three GM (Glass Molded Aspherical) lens elements, and several specialized elements. These components work cohesively to minimize peripheral blurring and color fringing while correcting sagittal coma flare—a frequent issue in astrophotography—ensuring crisp sharpness from the center to the corners of the frame. As Tamron points out, whether you’re photographing starry night skies or dimly lit interiors, this lens performs exceptionally well in any setting.
In addition to its “exceptional imaging performance,” the lens maintains a perfect balance between size and weight. Measuring only 119.3mm (4.7in) in length and weighing a mere 570g (20.2oz), it is compact yet retains professional-grade functionality with various switches and rings for optimal operability.
The autofocus system is powered by VXD (Voice-coil eXtreme-torque Drive), a fast and precise linear motor focus mechanism. With a Minimum Object Distance (MOD) of 0.18m (7.1in) at the 12mm wide end, the lens provides “outstanding close-up performance for creative versatility,” allowing photographers to get as close as 50mm (2in) from the lens front to the subject.
Equipped with a dedicated rear filter holder, the lens accommodates commercially available sheet-type filters. This setup allows users to cut a filter sheet to the necessary size and place it in the holder, expanding creative control, especially useful for long exposure photography.
The Tamron 12-20mm F2.8 is compatible with the exclusive Tamron Lens Utility application, which lets users assign practical functions for both video and still photography directly on the lens. This integration eliminates the need for external video equipment, streamlining the creative process and broadening shooting possibilities.
The 12-20mm F2.8 is priced at $1,699.00 for the Sony E mount version and $1,799.00 for the Nikon Z mount version.
