Lens Overview

Capture your most expansive imagination

The TAMRON 20mm F/2.8 Di III OSD M1:2 (Model F050) is the ideal first ultra-wide-angle lens for any photographer. Designed exclusively for Sony E-mount full-frame mirrorless lens cameras, the F050 is a creative tool that dynamically captures scenery by maximizing the perspective unique to ultra-wide-angle lenses. It’s lightweight and compact and provides an incredibly short 4.3″ MOD and a 1:2 maximum magnification ratio, making it possible to get closer to your subjects than you’d ever imagined. With Moisture-Resistant Construction and dirt-resistant Fluorine Coating, photographers can shoot confidently outdoors.

Ultra Wide-Angle Prime with Exceptional Close-Focusing Capability

The TAMRON 20mm F/2.8 Di III OSD 1:2 Macro is a prime lens for full-frame Sony E-mount mirrorless cameras. Offering a broad 20mm focal length and a fast F/2.8 aperture, it excels in low-light conditions and delivers beautiful bokeh. This lens stands out with its close-focusing capability, achieving a 1:2 maximum

magnification ratio and a minimum focusing distance of 0.11m, ideal for macro-like shots. Compact and lightweight, it features TAMRON's OSD autofocus motor for fast, precise, and quiet focusing. Its moisture-resistant design and fluorine coating ensure durability, making it perfect for diverse shooting conditions.

Get closer to your subject with 1:2 Macro

One of the key features that makes this lens so exciting is its amazing ability to shoot close-ups. With this lens, you can get closer to an object than you’d ever imagined. At the 0.11m (4.3″”) MOD, the lens achieves its maximum magnification ratio of 1:2. This remarkable performance allows users to create compositions that exploit dramatic perspective (closer subjects are larger, and distant ones are smaller) and that are unique to wide-angle lenses. By getting close to an subject, you can produce a one-of-a-kind photo and leverage the beautifully blurred background bokeh.

Ultra wide-angle lens that delivers outstanding optical performance for your creative vision

This lens provides outstanding optical performance and overall image quality, characteristics relentlessly demanded from a prime, fixed focal lens. The expert arrangement of the LD and GM specialized glass elements greatly controls aberrations, including chromatic aberrations. TAMRON’s proprietary BBAR (Broad-Band Anti-Reflection) Coating reduces ghosting and flare, which can otherwise occur when taking a photo against the sun. Moreover, leveraging your camera body’s features* it delivers, throughout the frame, high resolution performance that maximizes the benefits of the latest high-megapixel cameras. Whether shooting on the street, full-scale landscapes or architectural photography, this lens delivers exceptionally crisp, colorful and beautiful images and helps you fulfill your creative ambitions.

The extreme portability enhances the limitless versatility of the lens

This lens travels as well as it performs. And because it’s matched to lightweight full-frame mirrorless cameras, your entire system becomes light, fast and nimble. It has a very compact body, weighing just 220g (7.8oz) and an overall length of 64mm (2.5″”). It’s comfortably portable, highly maneuverable and amazingly easy to use and compose. Because the overall length does not change when focusing, you can get as close to an object as you need to without fear of accidentally bumping the front element. The lens has the same 67mm filter diameter as the other members of this prime series of 20mm, 24mm, and 35mm, as well as many of the zooms, for Sony E-mount cameras. So you can swap filters like circular polarizers, lens caps and other accessories for convenience.
