The Tamron 16-30 mm f/2.8 Di III VXD G2 is a professional ultra-wide zoom lens designed for full-frame mirrorless systems with Sony E and Nikon Z mounts. Its constant f/2.8 aperture ensures consistent exposure across the zoom range, while the VXD (Voice-coil eXtreme-torque Drive) autofocus system delivers fast, silent, and accurate performance even with moving subjects. The extended focal range from 16 mm to 30 mm provides more compositional flexibility compared to older 17–28 mm models, covering a wider set of shooting scenarios. Its optical construction consists of 16 elements in 12 groups, including XLD, LD, and GM components to control chromatic aberrations, flare, and distortion, resulting in sharp, high-quality images with strong edge performance. The design is compact—about 440 g for the Sony E version and a length of 101.8 mm—with a 67 mm front filter thread. The internal zoom mechanism keeps the physical length constant during zooming, improving balance when handheld or on a gimbal. Minimum focusing distances are 0.19 m at 16 mm and 0.30 m at 30 mm, yielding a maximum magnification of 1:5.4 in the wider range. The build is weather-sealed and includes a fluorine coating on the front element to aid in cleaning under harsh conditions. With compatibility with Tamron Lens Utility, you can customize functions and update firmware via USB-C. This lens blends high performance, versatility, and portability—ideal for landscapes, architecture, astrophotography, and creative video work.
