Tamron Di III A068 17-50mm
The Di III VXD 17-50mm F4 is the first lens to cover ultra-wide to standard focal lengths at a constant aperture, weighing 460g with weather sealing and a VXD linear motor for silent AF. Its 0.19m minimum focus distance at the wide end and moisture-resistant construction make it a practical walk-around for both stills and gimbal-mounted video. Best for macro photographers needing close focus and professionals seeking a compact, full-frame zoom with consistent exposure across the 17-50mm range.
