Tamron Di III A046 17-28mm
A constant f/2.8 aperture across the 17-28mm zoom and an RXD stepping motor deliver sharp, low-light imaging with silent autofocus for video. The 420g weather-sealed body and 67mm filter thread keep it compact for travel, while a 9-blade diaphragm produces smooth bokeh. Best for Sony E-mount travel photographers and vloggers needing a lightweight, ultra-wide zoom for landscapes, street scenes, and handheld video.
