The Tamron 70–300mm f/4.5–6.3 Di III RXD is the smallest and lightest full-frame Z-mount 300-mm-capable zoom lens in the world. What, exactly, does that mean? We’re talking a weight of just 20.5 oz and a length of only 5.9 inches. 300mm in a barrel that can fit on a 4×6 print? Now that’s what I call travel convenience!
As we’ve come to expect of this series of lenses, Tamron has focused on maximizing convenience without sacrificing quality. A few highlighted features:
- The RXD (Rapid eXtra-silent Drive) uses a stepping motor to drive the precision autofocus system without ruining the audio in your videos.
- An emphasis in engineering on avoiding the chromatic aberration common in long zoom lenses, as well as ensuring extremely high resolving power from edge to edge..
- Surprisingly nice bokeh for a compact telephoto lens.
- High quality coatings minimizing light distortion and protecting your investment.
