The Tamron 12-20mm F2.8 lens combines a sleek, lightweight structure with versatile control features, tailored to the rigorous demands of professional astrophotographers.
Designed for full-frame mirrorless cameras, the standout characteristic of the 12-20mm F2.8 (Model A084) is its ultra-wide focal range starting at an impressive 12mm. Although other lenses may start at 14mm or 16mm, the expansive 12mm offers, as Tamron states and many photographers would agree, “an unparalleled sense of scale.” This focal length allows for a dynamic capture of everything from majestic architecture to sweeping landscapes.
The lens’s wide 12mm perspective, which captures an entire scene with dynamic flair, is enhanced by a bright F2.8 maximum aperture throughout its zoom range. This makes it an ideal tool, dubbed by Tamron as the “new protagonist” in the realms of astrophotography and interior shooting.
The potential of this lens is undeniable, featuring an optical system with an XGM (eXpanded Glass Molded Aspherical) lens element, three GM (Glass Molded Aspherical) lens elements, and several special lens elements. These components work together to minimize peripheral blurring and color fringing while correcting sagittal coma flare, a common issue in astrophotography. This ensures exceptional sharpness across the entire frame, making it perfect for capturing starry skies or low-light interiors.
Despite its impressive imaging capabilities, Tamron emphasizes that the lens maintains a perfect balance of size and weight. It measures just 119.3mm (4.7 inches) in length and weighs a mere 570g (20.2 ounces). Its compact design doesn’t compromise on functionality, featuring multiple switches and rings that ensure superior operability.
Equipped with the VXD (Voice-coil eXtreme-torque Drive), the lens boasts a high-speed, high-precision linear motor focus mechanism. Additionally, with a Minimum Object Distance (MOD) of 0.18m (7.1 inches) at the 12mm wide end, it offers impressive close-up performance. You can focus as close as 50mm (2 inches) from the front of the lens to your subject.
Its lens mount includes a unique rear filter holder, accommodating commercially available sheet-type filters. Users can cut a filter to the required size and insert it into the holder, ideal for long-exposure photography.
The 12-20mm F2.8 is compatible with the Tamron Lens Utility application, which allows users to assign practical functions for both video and still photography directly to the lens. This feature negates the need for additional video equipment or complex setups, streamlining creative workflows and enhancing shooting possibilities.
The 12-20mm F2.8 is priced at $1,699.00 for the Sony E version and $1,799.00 for the Nikon Z version.
