Tamron's 11-20mm F2.8 Di III-A2 lens is a fast-aperturing ultra-wide-angle lens ideal for Canon's RF-series mirrorless cameras. It features a constant f2.8 maximum aperture and is ideal for shooting in landscape, architectural, and astro photography. The addition of a bright f/2.8 aperture to this range allows you to control the depth of field and improve low-light performance. Its optical design features a combination of two LD elements and one XLD element, which produce a highly accurate and corrected image.

It helps suppress ghosting and flare for enhanced contrast when shooting in low-light conditions.

Its quick response time and responsive RXD motor make it ideal for capturing stills and video. 

The lowest minimum object distance of the lens is just 5.9 inches, which allows it to shoot wide-angle macro shots with a unique perspective.

The maximum f/2.8 aperture allows you to create a soft bokeh effect by producing a shallow depth-of-field.

Its built-in fluorine coating also helps prevent dirt and dust from damaging the lens.

This versatile zoom can be used with Canon's RF-series APS-C mirrorless cameras with a maximum focal length range of 18 to 32mm.

The constant f2.8 maximum aperture allows you to maintain consistent brightness even throughout the zoom range. It also offers a better control over the depth of field.

The three glass-modified Aspherical elements in the lens' body, namely the XLD, GM, and LD, help minimize chromatic aberrations, image distortion, and color fringing even throughout the zoom range.

The BBAR-G2 coating has been utilized on the lens' elements to suppress ghosting, flare, and internal reflections for enhanced color fidelity and contrast.

The Canon's new RXD motor is designed to provide impressive quiet performance when it comes to focusing.

It's ideal for shooting stills and video applications.

The maximum aperture of the lens helps you create a shallow depth of the field and produce a soft bokeh effect.

It's also ideal for exploring dynamic wide-angle perspectives.

This lens is constructed with a moisture-resistant outer surface and a fluorine coating for enhanced protection against dirt and dust.

The seven-blade diaphragm helps create a pleasing and smooth bokeh effect.
