I series
Premium Compact Primes for Mirrorless Users

The SIGMA I series features full-frame-compatible lenses that offer mirrorless users a new and better alternative, both in the experience of shooting with the lens and in the impressive results it is able to achieve and this new 24mm optic is designed to be perfectly matched to the Mirrorless compact camera systems without sacrificing performance. This combination of superb optical quality with exceptional portability, not previously possible with DSLR systems, will bring new opportunities to this and future generations of photographers.

New Standards of Optical Performance for
the Contemporary Line

The SIGMA 24mm F2 DG DN | Contemporary for Sony E-mount, like the SIGMA 35mm F2 DG DN | Contemporary and the SIGMA 65mm F2 DG DN | Contemporary, combines the highest level of optical performance even at its maximum aperture of F2 and a well-balanced body.

The lens uses two SLD glass elements and one FLD glass element to correct axial chromatic aberration, which is a particular concern with bright lenses. It also incorporates two high-precision glass-molded aspherical elements, made possible by the processing technology of SIGMA’s sole production facility in Aizu.

Exceptional I series Build Quality
With a Compact Form-Factor

All I series lenses have an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability that improves the quality of the entire product.
