17–50 Tamron 17-50mm F4 Di III VXD

The Tamron 17-50mm F4 Di III VXD is a zoom lens for Sony E-mount (Full frame) that covers 17-50 mm at f/4, weighs 460 g and focuses as close as 0.19 m at 17 mm, 0.3 m at 50 mm. Next to 12 other full frame Sony E-mount zoom lenses in its focal range, it suits you if you carry it all day or travel light, or you want a wider view at the short end. If you shoot in low light or want a blurrier background, each other one that does better on brightness gives up at least one of weight and width. If you want more reach at the long end, every other one that does better on reach gives up width.

  1. Tamron product specifications, checked Oct 6, 2026

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.

    Lower wins once they are 5 mm apart.

  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.
