An interesting review of a very attractive lens, one of the few Sigma lenses which may some day make me overlook the company's compatibility issues.
One things that's a bit odd is the increased distortion at 12mm. If I recall, the previous version of this lens had very low distortion, even at this extreme focal length. Are you aware of any changes in the optical formula which may have resulted in this regression?
