Ultra-wide zoom for Canon RF APS-C

The Tamron 11-20mm f/2.8 Di III-A RXD is built for Canon RF-mount APS-C mirrorless cameras. It covers an 11-20mm focal range that equals 18-32mm in 35mm terms. A constant f/2.8 aperture runs through the whole zoom range. The kit adds a 67mm three-piece filter set, a cleaning kit and a lens-cap keeper.

Landscape, astro and architecture shooters

Photographers who need an ultra-wide perspective with fast aperture for low light and depth-of-field control will benefit. The 5.9-inch minimum focus distance at 11mm allows wide-angle macro work. Shooters requiring full-frame coverage or longer telephoto reach should look at other lenses.

Constant f/2.8 aperture across 11-20mm

The fixed maximum aperture does not change when zooming, so exposure stays consistent for video and stills. This single spec decides whether the lens matches a workflow that demands constant brightness throughout the ultra-wide zoom range.

Questions about this item

Should I choose the 67mm filter kit or a different size?

The included 3-piece filter kit matches the 67mm thread on this lens, so no other size is needed for standard protection or effects.

What does the constant f/2.8 aperture mean when I shoot indoors?

The aperture stays at f/2.8 throughout the 11-20mm zoom, giving consistent exposure and shallow depth of field even in low light.

How does the Canon RF mount affect the field of view on my APS-C camera?

On an APS-C sensor the 11-20mm range equals an 18-32mm equivalent, delivering ultra-wide coverage for landscapes and architecture.
