Sigma 50mm f/2 DG DN Contemporary Lens
The Sigma 50mm f/2 DG DN Contemporary Lens adds the classic standard prime lens focal length to the all-metal SIGMA “I series”.
This is the fifth f/2 I series lens to date, joining the 20mm, 24mm, 35mm, and 65mm lenses.
All f/2 I series lenses feature an arc-type AF/MF switch and a stylized ring on the all-metal barrel.
