11–20 Tamron 11-20mm F2.8 Di III-A RXD

The Tamron 11-20mm F2.8 Di III-A RXD is a zoom lens for Fujifilm X (APS-C) that covers 11-20 mm at f/2.8, weighs 335 g and focuses as close as 0.15 m at 11 mm, 0.24 m at 20 mm. Next to 2 other APS-C Fujifilm X zoom lenses in its focal range, it suits you if you carry it all day or travel light, or you shoot in low light or want a blurrier background. If you want more reach at the long end, or your body has no in-body stabilization or you shoot handheld video, every other one that does better on reach, or stabilization gives up weight and brightness.

Worked out by code, not stated by a source

  • Focal length and widest aperture as the lens's own name states them.
  • Read from the lens name: each maker marks the sensor size a lens covers (Sony FE/E, Canon RF/RF-S, Nikon DX, Tamron Di III/Di III-A, Sigma DG/DC); every Fujifilm X lens is APS-C and every Micro Four Thirds lens is Four Thirds.
  • Read from the lens name: Sony marks optically stabilized lenses OSS, Canon IS, Nikon VR, Fujifilm OIS, Panasonic O.I.S., Tamron VC and Sigma OS; a lens from these makers without the mark has no optical stabilization.
  • Prime or zoom, read from the focal length in the lens name.

  8. Lead for a pick1

Our pick or our take adds up the importance of each real difference, with these importances and thresholds: a gap smaller than its row's threshold is too close to call and counts as the same. They are our editorial choice, not a measurement, the same on every page, and they never read prices, sales or who sells it.
