Tamron 11-20mm F2.8 Di III-A RXD lens for Canon EOS RF-S 

With an aperture of F/2.8 – this is a zoom that lets you rediscover the beauty of the world.

• APS-C | f/2.8 to f/16
• 16.5-30mm (35mm Equivalent)
• Fast Ultra-Wide Angle Zoom
• Rapid eXtra Silent Stepping Drive Motor
• 1x XLD, 2x GM Asph., and 2x LD Elements
• BBAR-G2 Lens Coating
• Weather-Sealed Construction
• Rounded 7-Blade Diaphragm

The 11-20mm F / 2.8 Di III-A RXD is the perfect choice for gripping perspectives and extraordinary viewing angles. It is so light and compact that it’s almost hard to believe that this is the world's first1 ultra-wide-angle lens for mirrorless APS-C system cameras with Sony E-mount with an aperture of F/2.8. In fact, it is so handy that it is ready to hand in any situation and is ideally suited for dynamic video recordings with a gimbal.

Special optical glass ensures an optimally corrected, sharp and detailed image. The short close-up distance - only 15 cm at the shortest focal length and 24 cm at the longest focal length - allows spectacular close-ups that you would not have thought possible.

Regardless of the respective shooting distance, the RXD (Rapid-eXtra-silent stepping drive) autofocus motor focuses precisely and quickly on the subject. The focus is almost completely silent; thus no annoying operating noises are recorded during video recordings.

Immerse yourself in the fascinating world of wide-angle macro photography!

The closest focusing distance of the 11-20mm F/2.8 is only 15 cm with the shortest focal length. This means: With this lens you can get as close to the motif as you want - up to the largest possible image scale of 1:4. A dramatic effect of depth results due to the exaggerated gradation of the proportions. The steep decrease in image size makes close objects appear huge and distant objects appear tiny. With the aperture fully open (F/2.8), the depth of field is low, so that areas that are important to the image can be emphasized through the targeted use of sharpness and blurring (bokeh).

Brilliant and fast zoom duo for mirrorless APS-C system cameras

This duo is unique in terms of compactness, speed and image quality: The 11-20mm F/2.8 Di III-A RXD (model B060) and the 17-70mm F/2.8 Di III-A VC RXD (model B070) together cover the entire focal length range from 11mm to 70mm (35mm equivalent 16.5mm up to 105mm) with a constant aperture of F/2.8. Nevertheless, the fast combination weighs only 860g. The lens duo 11-20mm F/2.8 and 17-70mm F/2.8 is thereby the ideal choice for everybody who likes to travel light and wants to capture their experiences in outstanding images. Both zoom lenses also have the same size filter thread (ø 67 mm). The same filters and lens caps can therefore be used on both lenses. This saves weight during transport and valuable time when changing lenses.

• (MR) Moisture Resistant Construction – The lens is splash-resistant. All critical areas have special seals. Lenses with this feature are ideal for outdoor use in bad weather.
• (IF) Internal Focus – Internal focusing prevents the barrel from extending and rotating during focusing. The lens is easier to handle and is suitable for use with polarising or gradation filters.
• (BBAR G2) Broad Band Anti-Reflection– The BBAR multi-coating ensures brilliant images with natural colours. It reduces the reflection of light rays hitting the lens surface. The more advanced BBAR G2 coating has been used since 2019.
• (FLR) Fluorine Coating – Fluorine Coating protects the front lens from contamination. It prevents oil and water droplets from sticking to the surface. Fingerprints and dirt are easier to remove.
• (LD) Low Dispersion – LD elements have particularly low colour dispersion index. They reduce chromatic aberrations that appear as colour fringes on the contrast edges and reduce image sharpness.
• (XLD) Extra Low Dispersion Glass
• Extra-Low Dispersion – XLD elements have particularly low colour dispersion index. They reduce chromatic aberrations that appear as colour fringes on the contrast edges and reduce image sharpness.
• (RXD) Rapid eXtra silent Drive
• Rapid Extra-Silent Drive – RXD autofocus is highly responsive, making it ideal for shooting stills and video of subjects in motion. A sensor constantly detects the current focus setting, allowing the continuous autofocus (AF-C) to precisely target the rotation angle required for focus at lightning speed.
