Sigma has announced a new 20mm f/1.4 HSM lens that will be a member of their prestigious Art lineup. The other Art prime lenses recently introduced by Sigma have received rave reviews and have earned a place in many professional photographers bags as dependable, superior quality optics. I am anxious to see if the 20mm f/1.4 lives up to the reputation of the other Art lenses. Kudos to Sigma for taking on such an amazing feat as creating a 20mm f/1.4 full-frame compatible lens! The Sigma 20mm f/1.4 HSM Art lens is expected to begin shipping in Mid November, 2015 and will sell for $899. Read more Sigma adds 20mm f/1.4 to Art Lens Prime Lineup
