Tamron Co., Ltd. (President & CEO: Shogo Sakuraba; Headquarters: Saitama City, Japan; “TAMRON”), a leading manufacturer of optics for diverse applications, announces the launch of the 12-20mm F2.8 (Model A084), a fast-aperture ultra wide-angle zoom lens, compatible with Sony E-mount and Nikon Z mount full-frame mirrorless cameras.

The defining feature of the 12-20mm F2.8 (Model A084) is its ultra-wide focal range, from 12mm to 20mm. The overwhelming breadth of the 12mm perspective enables dynamic expression that seems to "capture the entire expanse of a scene." With a bright F2.8 aperture maintained throughout the entire zoom range, this lens is poised to become the "new protagonist" for astrophotography and interior shooting.
The optical system incorporates an XGM (eXpanded Glass Molded Aspherical) lens element, three GM (Glass Molded Aspherical) lens elements, and multiple special lens elements. This design effectively suppresses peripheral blurring and color fringing while correcting sagittal coma flare — a common challenge in astrophotography — ensuring high sharpness from the center to the extreme edges of the frame.
Despite its exceptional imaging performance, the lens achieves a sophisticated balance of size and weight, measuring just 119.3mm (4.7in) in length and weighing only 570g (20.2oz). 1 While compact, it remains a professional-grade tool equipped with various switches and rings for superior operability.
For autofocus, the lens features the VXD (Voice-coil eXtreme-torque Drive), a high-speed, high-precision linear motor focus mechanism. Furthermore, with an MOD (Minimum Object Distance) of 0.18m (7.1in) at the 12mm wide end, the lens offers outstanding close-up performance for creative versatility.
