Until they do, the only wide-angle zooms that Canon makes that come close are the <a href="http://www.canonrumors.com/reviews/review-canon-ef-16-35mm-f2-8l-ii/" title="16-35mm review" target="_blank">16-35 f/2.8 L II</a> or the <a href="http://www.canonrumors.com/reviews/review-canon-ef-8-15-f4l-fisheye/" title="8-15mm review" target="_blank">8-15mm f/4L Fisheye</a>.</p>
