Sigma 12-24mm f/4 DG HSM Art Lens Vs. Sigma 12-24mm f/4.5-5.6 II Lens VS. Canon EF 11-24mm f/4L USM Lens:
Overall, this is a very strong showing for Sigma. Yes, it is outperformed by the Canon lens for overall score, but given that the cost of the Canon is almost double, for many users, the Sigma will be just as good. While Canon will point to its hand-ground aspherical lenses as a key factor and the reason for the difference in cost, given that the performance is so similar, it seems Sigma’s molded aspherical elements are almost a match… and let you keep a big chunk of money in your pocket. Of course, choice is personal. If you’re looking for an ultra-wide lens, both the Canon and Sigma Art will offer great performance in this range, but in terms of value for money, the Sigma 12-24mm f/4 DG HSM Art wins hands down.
