The 28-300mm f/4-7.1 Di III VC VXD Lens from Tamron gives users the ability to capture wide-angle scenes as easily as intimate close-ups. Designed for Sony E-mount mirrorless camera systems, this lens has a complementary lightweight design, weighing just 1.3 lb. Its moisture-resistant design coupled with a fluorine coating on the front lens element contributes to its overall dependability out in the field and helps prevent users from being hindered by liquids, dust, and fingerprints sticking to the lens glass. Driven by Tamron's VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism, high-speed autofocus performance and precision are enabled. Users can expect smooth focus tracking that accommodates sudden movements made by your subject. The lens construction of the 28-300mm f/4-7.1 incorporates 20 elements in 13 groups, including one XLD (eXtra Low Dispersion), one LD (Low Dispersion), and three GM (Glass-Molded Aspherical) lenses, effectively controlling chromatic aberrations. Tamron Lens Utility software compatibility allows for changing lens settings, assigning camera body functions, and updating firmware.
