Tamron is bringing its fast 20-40mm zoom to Z-mount

Tamron has announced that it will be bringing its full-frame 20-40mm F2.8 Di III VXD lens to Z-mount. The lens originally launched in 2022 for E-mount, but now it’ll be available for Nikon shooters.

Optically, the lens is unchanged, featuring a 12-element, 11-group construction with four low dispersion elements, two molded glass aspherics and one hybrid aspheric. It has a minimum focusing distance of 0.17m (6.7″), and allows for a maximum reproduction of 1:3.8 (around 0.26x) at its wide end. It has 9 aperture blades.

One of the appeals of a zoom lens with a relatively limited focal range is its size and weight. The Z-mount version of the 20-40mm is 89mm (3.5″) long, and is 380g (13.4oz). There are very few lenses that you could consider direct competitors to this; other Z-mount ultrawide zooms will either start wider, and not go as tight, or start a bit tighter, and go further. Perhaps the closest analog is Sigma’s 20-60mm F2.8-4, which is around the same weight, but isn’t available for Z-mount and can only achieve F2.8 at its very widest setting.

Odd focal lengths have always been a staple of Tamron’s lineup though, and the company has lenses that you could use alongside it to go wider (the 12-20mm F2.8) or further (35-100mm F2.8 or 35-150mm F2-2.8) without leaving any gaps in coverage.

As the VXD in its name indicates, the lens uses linear motors for autofocus, which should make for smooth and fast focusing. That could be especially useful for video, as the lens’s focal range seems like a natural fit for vlogging. It’s threaded for 67mm filters, as are many other Tamron lenses, and the company says it’s sealed for dust and moisture resistance.

The Z-mount 20-40mm F2.8 Di III VXD costs a bit of a premium over the $699 E-mount version, retailing for $729. That is, however, still less than you’d pay to buy the version made for Sony cameras and an adapter, and may offer a more consistent experience. The lens will be available starting October 22nd.
