Z-mount is getting its first Sigma zoom lens: a 16-300mm for APS-C

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 123mm (4.8″) long and 625g (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.
