I recently had a few minutes to quickly shoot with a very interesting new Sigma lens, the ultra-wide 8-16mm zoom. This lens is only for APS-C crop digital cameras and on my EOS-7D, which shot the test photos in the gallery, it equates to a (rounded off) 13-26mm zoom, in 35mm full-frame equivalent terms. Very very wide indeed!
