Product details
In the era of mirrorless cameras, the balance between performance and size is even more crucial. There is a growing demand for compact, high-performance, high-quality lenses, and SIGMA responds to this call with the Sigma 20mm f/2 Lens.

The new 20mm f/2 DG DN | C features the signature arc-type auto/manual focus switch, dust, splash-resistant mount, and magnetic lens caps.
