Featuring a flexible wide-angle range, the Tamron 17-28mm f/2.8 Di III RXD is a versatile zoom for Sony E-mount full-frame mirrorless cameras. Covering ultra-wide to wide focal lengths, this lens is particularly suited to landscape, astrophotography, and architectural photography. Its bright constant f/2.8 maximum aperture complements this range and offers greater control over depth of field as well as improved low-light performance. The optical design incorporates XLD and LD elements, which produce a highly corrected image with reduced chromatic aberrations and color fringing for improved clarity and color accuracy. Individual elements also feature Tamron's BBAR coating, which suppresses flare and ghosting for improved contrast when working in backlit and difficult lighting conditions. Additionally, for added versatility, an RXD stepping motor enables fast, near-silent autofocus performance suitable for both stills and video, along with full-time manual focus override and a minimum focusing distance of 7.5". Suitable for using this lens in adverse weather conditions, it also features a moisture-resistant construction as well as a fluorine-coated front element to protect against fingerprints and smudges.
