Capture your most expansive imagination

F/2.8 ultra wide-angle, close focusing, fixed focal lens for Sony E-mount full-frame mirrorless cameras

The 20mm F/2.8 Di III OSD M1:2 (Model F050) is fast handling and packs expressive power that is the signature of fixed focal lenses. It's the ideal first ultra wide-angle lens for any photographer. It is designed exclusively for mirrorless cameras.

Light weight and compact, the Model F050 is extremely portable, ideal for situations where you need to travel light. The Model F050 is a creative tool that dynamically captures scenery by maximizing the perspective unique to ultra wide-angle lenses. The incredibly short 0.11m (4.3 in) MOD (Minimum Object Distance) makes it possible to get closer to your subjects than you'd ever imagined. In addition to the F/2.8 aperture, the Model F050 is constructed using special glass materials including LD (Low Dispersion) and GM (Glass Molded Aspherical) lens elements effectively arranged to quash aberrations.

The Model F050 provides outstanding optical performance across the entire frame, and delivers a sharp image, right down to the texture of the subject. With Moisture-Resistant Construction and dirt-resistant Fluorine Coating, photographers can shoot confidently outdoors. If you can own only one ultra wide-angle, the Model F050 should be your first choice.

Get closer to your subject. As close as 0.11m.

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 in) MOD, the lens achieves its maximum magnification ratio of 1:2. You'll never again be frustrated because you cannot get close to an object while shooting. 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 object, you can produce a one-of-a-kind photo and leverage the beautifully blurred background bokeh.

The extreme portability enhances the limitless versatility of the lens

Take it with you anywhere. 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 (7.8 oz) and an overall length of 64mm (2.5 in). 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 the series of Tamron high-speed lenses for Sony E-mount cameras. So you can swap filters (like polarizers), lens caps and other accessories for convenience. Who says great things can't come in small packages?

Additional Features:

• Moisture-Resistant Construction protects your lens
  For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
  
  
• Circular Aperture to Produce a Smooth-Edged Bokeh
  A 7-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background light spots and avoids rugged aperture geometry.
  
  
• Fluorine Coating for protection and safe cleaning
  The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
  
  
• Advanced anti-reflection coating
  The application of BBAR (Broad-Band Anti-Reflection) Coating for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.
