The 70-300mm f/4.5-6.3 Di III RXD Lens for Nikon Z from Tamron provides a popular telephoto zoom range for the full-frame Nikon Z-mount mirrorless cameras. This lens spans a useful short- to long-telephoto range and measures just 5.8" in length with a maximum diameter of 3", and it weighs just 1.2 pounds. It offers optical performance with aberration correction that delivers high image quality. Tamron's RXD stepping motor unit provides high-speed, high-precision, and quiet operation and is compatible with in-camera features.  Versatile telephoto zoom is designed for full-frame Nikon Z-mount mirrorless cameras and can also be used with APS-C models where it will provide a 105-450mm equivalent focal length range. 15 elements in 10 groups with one LD (low dispersion) lens element precisely arranged to suppress axial chromatic and other aberrations that are likely to occur with telephoto zoom lenses. Minimum focusing distance of 31.5" to suit working with close-up subjects. A high-strength aluminum-magnesium alloy and moisture-resistant construction benefit this lens' use in inclement conditions
