Tamron 28-75mm f/2.8 Di III RXD Lens for Sony E

The Tamron 28-75mm f/2.8 Di III RXD is a fast standard zoom lens designed for Sony’s full-frame E-mount mirrorless camera system, covering a practical wide-angle to short telephoto focal range. The constant f/2.8 maximum aperture delivers consistent exposure and depth of field control throughout the zoom range, making it well suited to portraits, events, travel, and low-light shooting. Autofocus is driven by Tamron’s RXD stepping motor system, providing fast, quiet, and smooth focusing performance suited to both stills and video recording. The optical construction incorporates low dispersion and aspherical elements to manage chromatic aberration and maintain consistent image quality across the frame. A moisture resistant construction adds reliability in light outdoor use. Its combination of constant f/2.8 aperture, capable optics, and competitive price point make it a popular alternative to native Sony offerings in the standard zoom category. Compatible with all Sony FE mount full-frame and APS-C mirrorless cameras.
