Sigma 30mm f/1.4 DC DN Contemporary Lens (FUJIFILM X)

Sigma 30mm f/1.4 DC DN Contemporary Lens for FUJIFILM X
High-Speed Standard Prime – Ultra-Fast f/1.4 Aperture, Stepping AF Motor & Thermally Stable Composite Build

The Sigma 30mm f/1.4 DC DN Contemporary is a compact, high-speed standard prime lens designed for APS-C FUJIFILM X-mount mirrorless cameras. Delivering a 45mm full-frame equivalent focal length, this versatile lens closely mirrors the field of view of the human eye, making it an ideal choice for street photography, portraiture, documentary work, and everyday walk-around shooting. Its ultra-fast f/1.4 maximum aperture excels in challenging low-light environments while offering precise depth-of-field control for subject isolation.

The optical construction features two aspherical elements and one high-refractive index element to minimize spherical aberrations and distortion, ensuring high edge-to-edge sharpness and clarity. A Super Multi-Layer Coating is applied to reduce lens flare and ghosting under strong backlighting. Powered by a smooth, near-silent stepping AF motor, the lens provides rapid autofocus tracking for both photo and video applications. Constructed from a Thermally Stable Composite (TSC) material with a rubber-sealed brass bayonet mount, it maintains structural precision across temperature variations while offering protection against dust and moisture.
