For photographers looking to extend their reach, there are a few better options than a 70-300mm telephoto lens choice provides an excellent option for closer subjects and portraits while giving you the reach needed for bird and wildlife photography. Unfortunately, these lenses add quite a bit of heft to your setup and that’s where the Tamron 70-300mm F/4.5-6.3 Di III RXD hopes to differentiate itself from other Nikon Z telephoto options.

Why It Matters

The Tamron 70-300mm F/4.5-6.3 Di III RXD will be the first 70-300mm lens for Nikon’s Z mount system – offering Nikon mirrorless photographers an often requested focal length for birding and wildlife photography. Tamron is making the most of this photography segment by ensuring that the lens is weather-sealed and light enough to stow in a day bag (it only weighs in at 20 ounces). The addition of Tamron’s RXD stepping motor tech means you can expect quiet-to-no AF whir and gives you a solid telephoto option for video capture.

Pricing and Availability

While it’s not the fastest lens in this general range, it is a far more affordable option compared to Nikon’s 70-200mm f/2.8 (which comes in just under $2700 US) while providing for a longer focal range. The Tamron 70-300mm Di III RXD is expected to be available starting September 29, 2022, and will retail for around $699 – not bad even if you’re just thinking about rounding out your lens options.
