I do not plan to create a full Sigma 12-24mm f/4.5-5.6 EX DG HSM Lens review - hopefully the standardized results for this lens will be helpful to you.
Bringing you this site is my full time job (typically 60-80 hours per week). Thus, I depend solely on the commissions received from you using the links on this site to make any purchase. I am grateful for your support! - Bryan
