You’ll be amazed from the very first shot
The world's first1 fast-aperture F2.8 ultra wide-angle zoom lens for mirrorless invites new experiencesOffering the unprecedented brightness of constant F2.8 and outstanding portability, the 11-20mm F/2.8 Di III-A2 RXD (Model B060) is a fast-aperture ultra wide-angle zoom lens for Sony E and FUJIFILM X-mount APS-C mirrorless cameras. Since the fast F2.8 aperture lets you maintain a high shutter speed even when shooting in dark conditions, you can capture sharp images handheld with minimal shake. Also, special lens elements have been optimally arranged to suppress optical aberrations. These features combine to produce clear images and high-resolution performance throughout the zoom range. The lens is so lightweight and compact that it is hard to believe it is a fast-aperture ultra wide-angle zoom lens. This makes it ideal for everyday use, and for travel when you want to carry a smaller camera bag. The 11-20mm F2.8 achieves an MOD (Minimum Object Distance) of 0.15m (5.9 in) at the widest end and 0.24m (9.4 in) at the 20mm end, ensuring the ability to close in on subjects as you please. The lens also incorporates a fast precision AF drive system with an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit which is perfectly fit for still and video shootings. Moisture-Resistant Construction and Fluorine Coating join forces to offer additional protection when shooting outdoors. Everything you see, from daily life to travels, is within your photographic grasp with this lens. The 11-20mm F2.8 will expand your enjoyment of shooting by combining excellent portability with the ability to capture images unique to fast-aperture ultra wide-angle lenses.

High performance autofocus operates quietly and accurately captures subjects when shooing both still and video
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 highlights.
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
TAMRON has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.
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.

MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.
Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.
Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance
