Ultra-wide zoom for Sony E-mount

The Tamron 17-28mm f/2.8 Di III RXD is a constant-aperture zoom built for Sony full-frame mirrorless bodies. It covers an ultra-wide 17-28mm range at f/2.8 throughout, making it suited to landscape, architecture and interior photographers who need a bright, wide perspective in a single lens.

Compact build with moisture resistance

Weighing less than comparable f/4 designs, the lens adds minimal bulk to a mirrorless kit and uses a stepping RXD motor for quiet autofocus during stills or video. Moisture-resistant construction and a fluorine coating on the front element protect against dust and splashes, while the 9-blade rounded diaphragm produces smooth background rendition. XLD and LD elements plus BBAR coating suppress flare and chromatic aberration across the frame.

Consistent f/2.8 performance across the zoom

The fixed f/2.8 aperture maintains exposure and depth-of-field control from 17mm to 28mm without ramping, so metering stays predictable during extended shooting sessions. Optical corrections handled by the camera body keep distortion and vignetting low even at the widest setting, and the quiet stepping motor sustains reliable focus tracking without hunting during long takes or time-lapse sequences.
