70–300 Tamron 70-300mm F4.5-6.3 Di III RXD
The Tamron 70-300mm F4.5-6.3 Di III RXD is a zoom lens for Nikon Z (Full frame) that covers 70-300 mm at f/4.5-6.3, weighs 580 g and focuses as close as 0.8 m at 70 mm, 1.5 m at 300 mm. Lightest (580 g) of the 8 full frame Nikon Z zoom lenses in its focal range. Among them, it suits you if you carry it all day or travel light, or you want more reach at the long end. If you shoot in low light or want a blurrier background, or your body has no in-body stabilization or you shoot handheld video, every other one that does better on brightness, or stabilization gives up weight. If you want to focus closer at the wide end, every other one that does better on close focus gives up weight and reach.

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.

- 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.
