Sigma Lenses for Canon and Nikon DSLRs

Sigma is one of the younger and more entrepreneurial of the Japanese camera companies, founded in 1961 as Setagaya-ku, changing its name to Sigma in 1970. It's a small company in terms of infrastructure and permanent employees.

  • Art — designed "with a focus on sophisticated optical performance and abundant expressive power." Consists mostly of large aperture prime lenses, wide angle, and macro lenses. Examples: 30mm f/1.4, 35mm f/1.4, 18-35mm f/1.8, 24-105mm f/4, and 50mm f/1.4.
