Today, Sigma introduced its I series of lenses for full-frame mirrorless cameras. The line consists of three new Sigma lenses: the 24mm F3.5 DG DN, 35mm F2 DG DN and the 65mm DG DN.
We believe there is a growing demand for compact, high-performance, high-quality lenses,” reports Sigma America President Mark Amir-Hamzeh. “The introduction of the I series of full-frame mirrorless-exclusive lenses answers this call. The I series represents a new option: premium compact primes that are stylish in appearance with impressive specifications and optical performance.”

Sigma 35mm F2 DG DN | Contemporary
The Sigma 35mm F2 DG DN comes with a maximum aperture of F2 packed inside a small body.
