Technical Details

Tamron 12-20mm f/2.8 Ultra Wide Angle Lens for Sony E The Tamron 12-20mm f/2.8 Ultra Wide Angle Lens boasts a sophisticated optical design, incorporating one XGM (eXpanded Glass Molded Aspherical), three GM (Glass Molded Aspherical), one XLD (eXtra Low Dispersion), and three LD (Low Dispersion) lens elements.

This meticulously crafted combination effectively curbs optical aberrations, reducing peripheral blur and colour fringing, whilst ensuring remarkable sharpness across the entire frame. Furthermore, it rectifies sagittal coma flare, guaranteeing that point light sources remain sharp and distinct from the centre to the corners.

This makes it an outstanding selection for capturing nightscapes and astrophotography.

Key Features

• AX & BBAR-G2 Coating
• Enhanced Mobility for Landscapes
• High-Speed, High-Precision, and Quiet Performance
• Mastery of Light
• Practical Features for Everyday Use

AX & BBAR-G2 Coating

The lens is equipped with AX (Anti-reflection eXpand) Coating, which uses a uniform vapour-deposited film across highly curved convex elements to effectively suppress unwanted reflections and maintain exceptional image clarity.

Complementing this is the second-generation BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating, which significantly reduces ghosting and flare even in challenging backlit conditions, producing high-contrast images with vivid colour and remarkable visual impact.

Enhanced Mobility for Landscapes

Designed to balance outstanding optical performance with portability, the 12-20mm f/2.8 measures just 119.3 mm in length and weighs only 0.57 kg. Extensive optical and mechanical refinements, along with micron-level component adjustments and rigorous durability testing, ensure exceptional strength and reliability. Whether you're hiking to remote landscapes or setting up beneath the night sky, this compact lens reduces your load without compromising performance.

High-Speed, High-Precision, and Quiet Performance

Powered by the VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism, the lens delivers fast, accurate, and quiet autofocus performance. Its rapid response and precise focusing help capture decisive moments with confidence.

The lens also offers impressive close-up capabilities, with a minimum object distance of 0.18 m at 12 mm and 0.28 m at 20 mm, allowing you to shoot as close as 50 mm from the front of the lens for dramatic ultra-wide perspectives.

Additionally, compatibility with the Tamron Lens Utility application enables users to assign practical functions for both video and still photography, simplifying workflow without the need for external equipment.

Mastery of Light

A precision-engineered 12-blade circular diaphragm creates beautifully smooth, circular bokeh when shooting near maximum aperture while producing striking 12-pointed starburst effects when stopped down for nightscapes and cityscapes.

The lens also introduces Tamron's "Toned Profile Next" design, evolving its signature styling into a refined mechanical aesthetic that combines a sleek appearance with the durability and functionality demanded by modern photographers.

Practical Features for Everyday Use

The lens includes an integrated flower-shaped hood that helps minimise flare and ghosting by blocking stray light, allowing the optical system to perform at its best.

A dedicated locking front lens cap fits securely over the integrated hood for added protection during transport, while the integrated rear filter holder accepts commercially available sheet-type filters for greater creative flexibility.

To help keep the lens protected in your camera bag, Tamron also includes a compact self-gripping wrapping cloth that shields it from dust and scratches while remaining easy to fold and carry.
