Adorama is clearing out the Tokina AT-X 16-28mm f2.8 Pro FX for Canon — it’s only $399.95, discounted $230 from the regular price of $630. This is the lowest price we’ve seen yet for this very highly-reviewed lens. This wide-angle zoom lens (designed for full-frame sensors) was already terrific value, and this extra discount makes this deal hot.
As this is a clearance deal, it’s likely that stock is limited. It’s also available from Amazon (sold and shiped by Adorama).
