The Tamron 17-28mm F/2.8 Di III RXD is a fast, compact wide-angle zoom lens designed specifically for Sony Mirrorless full-frame cameras. Constructed so it weighs just 420g and measures less than 100mm in length, the lens barrel doesn't extend when focusing or zooming, ensuring perfect balance. High-speed and high-accuracy focus is achieved thanks to Tamron's Rapid eXtra-silent stepping Drive (RXD) focusing system which is also silent, making it ideal for both photography and videography.
Superb optical performance
The 17-23mm F/2.8 features a construction of 13 glass elements in 11 groups, including 3 aspherical, 2 low-dispersion elements, and an extra low-dispersion element. These elements marry together to suppress artefacts and aberrations, while Tamron's Broad-Band-Anti Reflection coating effectively reduces flares and ghosting.
Fantastic versatility
The 17-28mm focal length offers fantastic versatility as an all-day travel lens, while the lens can focus as close as 19mm on the widest focal length, and 26mm when zoomed in, with a magnification ratio of 1:5.2 – 1:6, allowing users to get creative with perspective in ways very few other lenses can achieve.
Outstanding AF performance
Tamron's Rapid eXtra-silent stepping Drive (RXD) focusing system offers high-speed and high-accuracy performance and is ideal for both video and photo work.
Built to last
The lens features moisture-resistant construction, offering protection when shooting outdoors in adverse weather conditions. The front glass element is coated with a protection fluorine compound which repels water and oils, making it easier to wipe clean and protecting it against dirt and fingerprints.
