Third-party reviews

Based on 283 buyer reviews from online shops.
Reviews last updated: July 2026 · How we calculate this

What we like about Tamron 11 20mm F 2 8 Di III A RXD

  • Fast and constant f/2.8 maximum aperture throughout the zoom range
  • Compact and lightweight design (approx. 335g), ideal for travel and vlogging
  • Exceptional optical sharpness, particularly in the center of the frame
  • Fast, silent, and accurate RXD (Rapid eXtra-silent stepping Drive) autofocus
  • Moisture-resistant construction with weather-sealing gaskets and fluorine coating
  • Close minimum focusing distance (15cm at 11mm) allows for creative wide-angle macro-style shots
  • Good control of flare and ghosting due to BBAR-G2 coating

What we don't like about Tamron 11 20mm F 2 8 Di III A RXD

  • Lacks built-in optical image stabilization (VC), relying entirely on camera IBIS
  • Noticeable barrel distortion at the 11mm wide end when uncorrected
  • Significant vignetting when shooting wide open at f/2.8
  • Some users report chromatic aberrations (color fringing) on high-resolution sensors
  • Omission of physical controls such as an aperture ring or AF/MF switch on certain mounts
  • Plasticky build quality may not feel as premium as some all-metal alternatives
  • Relatively high price point compared to some competitors like the Sigma 10-18mm

Verdict

The Tamron 11-20mm F/2.8 Di III-A RXD is a compact, fast-aperture ultra-wide zoom designed for APS-C mirrorless cameras, offering a constant f/2.8 maximum aperture and a 16.5-30mm full-frame equivalent focal range. Its optical construction includes 12 elements in 10 groups, featuring specialized XLD, LD, and GM aspherical elements with BBAR-G2 coating to minimize aberrations and flare. Main characteristics include a lightweight 335g build, moisture-resistant construction, and a Rapid eXtra-silent stepping Drive (RXD) motor for quiet, high-speed autofocus. Pros include excellent edge-to-edge sharpness, a 15cm minimum object distance for 1:4 macro capabilities, and a standard 67mm filter thread shared with other Tamron lenses. Cons include the lack of built-in optical image stabilization (VC), noticeable geometric distortion at the wide end if uncorrected, and occasional peripheral shading at narrower apertures.
