Characterized by its dramatic wide-angle perspective, this zoom has much to offer for photographers of all levels. The 12mm wide angle view makes this lens perfect for dramatic landscapes, and the fast, f/2.8 aperture delivers a bright view ideal for night skies and astro photography. Plus, the lens even offers stunning close-up performance with a minimum focus distance of just 7.1" at the wide end.
The lenses optical system incorporates an eXpanded Glass Molded Aspherical, or XGM, lens element alongside three Glass Molded Elements to effectively suppress peripheral blurring and color fringing, resulting in corner-to-corner sharpness. Additionally, the lens corrects for sagittal coma flare, a common challenge for astro photographers.
Ultra-wide zooms have traditionally been quite large, yet Tamron has achieved a sophisticated balance of size and weight. At just 20.2 ounces and measuring 4.7" in length, the lens among the smallest in its class. This feat is achieved with few sacrifices, as Tamron managed to slim down and fit all the necessary controls and switches users have come to expect from their lenses.
The Tamron 12-20mm f/2.8 Di III is one of the most impressive ultra-wide zoom lenses available for modern mirrorless systems, and a great solution for those looking for a dramatic perspective with impressive light gathering capabilities.
