Tamron 70-300mm f/4.5-6.3 RXD: full-frame reach at 545 grams

At 545g and 77mm long, this is one of the most packable full-frame telephoto zooms available for the Nikon Z system. The 70-300mm range covers a lot of ground, tight environmental portraits at 70mm, compressed mid-distance wildlife at 200mm, and distant subjects pulled in close at 300mm, all without swapping glass. A 67mm filter thread keeps circular polarizer and ND costs reasonable, and the moisture-resistant construction means you're not babying it at outdoor events or on overcast trail shoots.

The RXD (Rapid eXtra-silent stepping Drive) motor is tuned for mirrorless workflows, running quietly enough to avoid drawing attention during street or event work and fast enough to support the Eye AF tracking built into current Nikon Z bodies. Optically, the 15-element, 10-group design addresses chromatic aberration, a real concern across a zoom range this wide, through deliberate element placement than relying on post-processing correction. Minimum focusing distance sits at 0.8m, which gives you usable subject isolation at the short end and some flexibility for tighter environmental portraits.

For photographers moving from a DSLR kit, this lens undercuts the weight penalty that traditionally came with 70-300mm telephoto ownership. The reach is there; the bulk isn't.

Who It's For

Travel photographers working out of a single bag will appreciate the 545g weight and 77mm body length, real-world numbers that make a difference on a long day. Sports and wildlife shooters benefit from the RXD autofocus system's speed and its compatibility with Nikon Z Eye AF tracking for moving subjects. Portrait photographers wanting subject isolation and flattering compression without a heavy prime can work effectively across the 70-300mm range at 0.8m minimum focus. Hikers and outdoor shooters get moisture-resistant construction without stepping up to a heavier pro telephoto.

FAQ

How does the RXD motor perform during video or continuous AF tracking?
The RXD stepping motor is designed for mirrorless workflows with quiet, fast autofocus that supports Eye AF tracking on current Nikon Z bodies without the noise that draws attention during events or street work.
Is this lens actually smaller and lighter than traditional 70-300mm telephoto zooms?
At 545g and 77mm long, it's the world's smallest and lightest 70-300mm full-frame telephoto zoom. You get full telephoto reach without the bulk penalty of older DSLR designs.
What's the minimum focusing distance, and can you shoot portraits at 70mm?
Minimum focus is 0.8m (31.5 inches). At 70mm, you can frame environmental portraits with some subject separation, and the close focusing distance gives you flexibility for tighter compositions.
How does Tamron address chromatic aberration across such a wide zoom range?
The 15-element, 10-group optical design deliberately places special elements to correct chromatic aberration and other aberrations rather than relying on post-processing correction.
What filter size does this lens use, and is that practical?
67mm filters keep costs reasonable for circular polarizers and NDs without ballooning the front element diameter, which helps keep the overall lens compact.
Does the moisture-resistant construction make this lens weather-sealed?
Moisture-resistant construction provides extra protection for outdoor work, but this isn't a fully sealed lens - it's built to handle overcast trail shoots and outdoor events without babying it.
Which Nikon Z bodies does this lens work with?
It's designed for Nikon Z full-frame mirrorless bodies and supports features like Eye AF built into current Z camera firmware.
