Blending a sleek form-factor with a versatile working range, the 28-75mm f/2.8 Di III RXD from Tamron is a full-frame-compatible lens for Sony E-mount mirrorless cameras. Spanning wide-angle to portrait-length, a constant f/2.8 maximum aperture complements this range and affords increased control over depth of field along with enhanced low-light performance.

The optical design incorporates a series of low dispersion and aspherical elements, which produce a highly corrected image with reduced spherical and chromatic aberrations for improved sharpness and clarity.
