Sigma has put a $769 price tag and a November 5 on-sale date on a Nikon Z mount version of its 16-300mm f/3.5-6.7 DC OS Contemporary, bringing the company's 18.8x all-in-one zoom to Nikon's APS-C mirrorless bodies for the first time.

The lens is not new glass — it is a mount expansion of an existing Contemporary-line design. What is new is the availability: photographers invested in Nikon Z DX cameras can now buy Sigma's superzoom directly rather than adapting or shopping elsewhere. For working shooters who carry one body and one lens for travel, events or documentary assignments, the 16-300mm range covers roughly 24-450mm in full-frame equivalent terms on Nikon's 1.5x crop APS-C sensors.

What does the lens actually offer?

The headline specification is the zoom ratio: approximately 18.8x, stretching from a 16mm wide end to a 300mm telephoto end in a single barrel. The maximum aperture runs from f/3.5 at the wide end to f/6.7 at the long end — figures that put the lens firmly in the travel and daylight category rather than low-light professional work.

The "DC" designation confirms it covers APS-C sensors only; full-frame Z shooters will see vignetting if they try it. The "OS" label denotes Sigma's optical stabilization, a practical consideration for handheld work at the 300mm end, where effective focal lengths exceed 400mm equivalent. The Contemporary line sits in Sigma's mid-tier positioning, built for compactness and cost rather than the optical priorities of the Art series.

How does the price sit in the market?

At $769, the lens occupies the upper-middle band for APS-C superzooms. Nikon's own Z DX 18-140mm f/3.5-6.3 VR sells for substantially less but gives up 160mm of reach at the long end. Sigma's bet is that shooters will pay a premium for the extended range in a single lens.

For photo businesses, the calculation is straightforward:

• One lens replaces a wide-to-tele kit for APS-C coverage, cutting bag weight and lens-swap time on fast-moving jobs.
• The f/6.7 long end limits the lens to well-lit or stabilized scenarios; it is not a substitute for a fast telephoto in indoor sports or evening event work.
• The $769 outlay positions it against two-lens alternatives rather than a single Nikon-branded superzoom, since Nikon does not currently match this focal range in Z DX glass.

What happens on November 5?

The lens goes on sale November 5 at $769. Sigma has announced no additional mount variants or pricing tiers alongside this release. Whether the 18.8x range proves durable enough for professional daily use — superzooms historically trade optical compromise for convenience — will show up in real-world testing once units reach reviewers and working photographers next month.
