Sigma has announced that it’s bringing its 16-300mm F3.5-6.7 DC OS (24-450mm equiv.) APS-C lens to Z-mount. While it may not be the most exciting addition to the lineup – Nikon APS-C shooters have already had access to a very similar option from Tamron – it’s representative of what may be an important shift: it’s the first zoom lens the company has been allowed to release for the mount.

The 16-300mm F3.5-6.7 has been around for a bit over a year for Sony E, Canon RF, Fujifilm X and even L-mount cameras, and this new version uses the same optical formula. It comprises 20 elements in 14 groups, with one FLD element, four SLD elements, one piece of high refractive index glass and four aspherical lenses.

It can focus on objects as close as 17cm (6.7″) at 24mm equiv., and 105cm (41.4″) at 450mm equiv. At 70mm, it can achieve 0.5x (1:2) magnification.

It uses linear motors for focusing, and Sigma says the optical stabilization is good for up to 6EV of correction at the wide end and 4.5EV at the long end. For Z-mount users, that’s definitely a nice-to-have, given that Nikon hasn’t made any APS-C cameras with in-body stabilization.

As you’d hope given that it’s made for a smaller sensor, the lens is relatively compact and lightweight, at around 125mm (4.9″) long and 630g (22oz). It can accept 67mm filters.

All of these specs make the lens an extremely close competitor to the Tamron 18-300mm F3.5-6.3 Di III-A VC VXD, which, beyond not being able to go quite as wide as the Sigma, offers essentially the same set of features in a body that’s within a few millimeters and grams. (The Tamron happens to be the first third-party autofocus zoom lens released for Nikon’s APS-C system.)

While there will certainly be those excited to have another all-in-one zoom option, perhaps more exciting is what this announcement may potentially mean. Sigma has offered Z-mount versions of a few of its APS-C prime lenses for a while now, though, notably, not the one that directly competes with one of Nikon’s offerings. However, none of its quite good zoom lenses were available for the mount. While the 16-300mm arriving for Nikon systems doesn’t come close to guaranteeing that we’ll get more exciting options like the 17-40mm F1.8 DC Art, the just-announced 50-120mm F2.8 DC Contemporary or the 10-18mm F2.8 DC DN, it does seem like a bit more of a possibility today than it did yesterday.

Like the other versions of the lens, the 16-300mm F3.5-6.7 DC OS for Z-mount will cost $769.

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.
