Nikon’s October 29, 2026 US announcement introduces the NIKKOR Z 120–300mm f/2.8 TC VR S for professional sports photography. Its built-in 1.4× teleconverter is the headline convenience, but the aperture changes when that converter is engaged. A useful shooting plan needs the focal length and maximum aperture together.

Nikon USA’s October 29 announcement and footnotes

Write down both shooting modes

Nikon’s specification sheet lists 120–300mm with a maximum aperture of f/2.8 without the built-in converter. With it engaged, the range becomes 168–420mm and the maximum aperture becomes f/4. The f/2.8 in the product name does not describe the converted mode.

Nikon’s focal-length and aperture specifications

For a simple arithmetic exercise, multiply a 200mm zoom setting by 1.4: the result is 280mm. At the long end, 300 × 1.4 gives 420mm. Pair each converted result with f/4 as the widest available aperture. Treat this as reading the specification, not a test of image detail or autofocus.

Budget one stop when working wide open

Moving from f/2.8 to f/4 is one stop. Nikon’s general description of its separate Z TC-1.4x accessory also explains the one-stop aperture reduction associated with 1.4× conversion. That accessory page is background on the principle; it is not a test of the new lens’s built-in unit.

Background: Nikon’s explanation of 1.4× conversion

Consider a fictional exposure exercise with unchanged scene lighting. A photographer starts at f/2.8, 1/1000 second and ISO 3200. After changing to f/4, keeping 1/1000 second would call for ISO 6400 for the same nominal exposure brightness. Alternatively, keeping ISO 3200 would call for 1/500 second. These are illustrative settings, not recommended settings for a particular event.

That trade-off becomes a useful trial question: does the extra reach help enough for the shot you need? Keep a record of the chosen mode, shutter speed, ISO and result. Compare your own files before deciding which compromise works for the assignment. The arithmetic alone cannot establish image quality.

Check the availability statement separately

Nikon USA announced mid-November 2026 availability and a suggested retail price of $13,999.95. It says dealers set actual prices and dates can change. This is a US announcement; it does not establish an Indian price, a local delivery commitment or current dealer stock.

If arranging a demonstration or rental, ask for the exact lens and camera combination, the confirmed dates and time to inspect the files afterward. Build the trial around a specific question, such as whether the converted mode gives the framing and results you need under your usual lighting. A list of specifications cannot answer that question for you.

Use a short comparison sheet

Give each test sequence its own entry: subject and lighting, converter position, exposure settings, and the observation you want to check. Review comparable sequences rather than selecting one attractive frame as the whole verdict. No lens, camera, retailer checkout or field performance was independently tested for this article.
