Sigma 12-24mm f/4.5-5.6 DG II HSM Lens Review
From The Digital Picture review:
“This lens is not without some shortcomings, but what it offers is available in no other lens. The Sigma 12-24mm f/4.5-5.6 DG II HSM Lens is the widest angle rectilinear lens available in a Canon, Nikon, Sony or Sigma DSLR mount. This unique capability will allow you to capture images that would otherwise not be possible and the quality of Sigma 12-24 II images can be also-impressive.”
