Tamron 70-300mm Di III RXD – Nikon Z

Reach Further Without the Bulk

The Tamron 70-300mm f/4.5-6.3 Di III RXD is proof that serious telephoto reach doesn't have to mean serious weight. Tipping the scales at just 1.2 pounds and stretching only 5.8 inches long with a 3-inch maximum diameter, this lens slots into your bag without compromise — yet delivers the kind of optical performance you'd expect from a much larger optic.

Designed specifically for full-frame Nikon Z-mount mirrorless bodies, it also pairs seamlessly with APS-C Z-mount cameras, where its effective focal range extends to an impressive 105-450mm equivalent. Whether you're tracking athletes on the field, capturing wildlife in motion, or isolating a portrait subject with beautiful background separation, this zoom adapts to every scenario with ease.

Precision Engineering, Inside and Out

Tamron's RXD stepping motor drives fast, accurate, and whisper-quiet autofocus — ideal for video shooters and photographers alike — while remaining fully compatible with in-camera AF features. Internally, 15 elements arranged in 10 groups include a dedicated LD (low dispersion) element that actively suppresses axial chromatic aberration and other optical distortions common in telephoto designs. A rounded seven-blade diaphragm shapes smooth, pleasing bokeh, and the lens supports in-camera correction for shading, chromatic aberration, and distortion. Built from a high-strength aluminum-magnesium alloy with moisture-resistant construction, this lens is ready when the weather isn't. Firmware stays current via Tamron Lens Utility software.
