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

Sigma 30mm f/1.4 DC DN Contemporary Lens (FUJIFILM X Mount)
The Sigma 30mm f/1.4 DC DN Contemporary is a fast, versatile standard prime lens engineered specifically for APS-C format FUJIFILM X-mount mirrorless cameras. Delivering a highly practical 45mm full-frame equivalent perspective, this lens sits perfectly between a wide and a short telephoto field of view, closely mimicking the natural human eye. As a standout entry in Sigma’s Global Vision Contemporary line, it masterfully strikes a balance between lightweight convenience and elite optical performance, making it an exceptional everyday walkaround choice for street photography, portraits, environmental journalism, and low-light documentation.

Ultra-Bright f/1.4 Aperture & Advanced Optical Layout
Fast f/1.4 Maximum Aperture: The bright f/1.4 aperture excels when shooting in low-light environments, allowing you to maintain lower ISO values while granting deep control over shallow depth of field for beautiful selective focus techniques.

Aspherical & High-Refractive Index (HRI) Glass: The internal optical arrangement features two aspherical elements and one HRI element to aggressively suppress geometric distortions, astigmatism, and spherical aberrations, ensuring high edge-to-edge sharpness and resolution.

Super Multi-Layer Coating: Individual glass elements are treated with Sigma’s multi-layered anti-reflective coating to control lens flare and internal ghosting. This preserves rich contrast and color neutrality, even when framing subjects against harsh backlighting.

9-Blade Rounded Diaphragm: Incorporates a rounded nine-blade aperture layout to deliver a smooth, circular background blur (bokeh) with natural-looking falloff.

Silent Stepping Motor AF & Robust Construction
Fluid Stepping AF Drive: Driven by a rapid stepping autofocus motor that delivers quick, precise, and virtually silent targeting. This smooth performance seamlessly accommodates both portrait photographers tracking fast-moving subjects and videographers requiring quiet rack-focus controls.

Thermally Stable Composite (TSC) Build: The lens barrel is constructed from a specialized Thermally Stable Composite material, which exhibits a thermal expansion behavior similar to aluminum. This guarantees mechanical structural precision through wide environmental temperature variations.

Weather-Sealed Brass Bayonet: Features a solid, high-rigidity brass bayonet mount for long-term mounting accuracy. A durable rubber sealing ring is integrated directly into the mount area to protect the lens-to-camera interface from dust and moisture intrusion.

Included Accessories
Dedicated Lens Hood Included: Ships complete with its original matching barrel-shaped lens hood, designed to block stray, off-axis light from causing internal flare while offering extra physical impact shielding to the front element.

Front & Rear Caps Included: Outfitted with front and rear lens caps to securely safeguard both ends of the optical system during storage or travel.
