Sigma 15mm f/1.4 DC Contemporary Lens (FUJIFILM X)

Sigma 15mm f/1.4 DC Contemporary Lens
The Sigma 15mm f/1.4 DC Contemporary is a revolutionary ultra-wide-angle prime lens specifically engineered for APS-C format mirrorless cameras. Delivering a versatile 22.5mm full-frame equivalent focal length, it masterfully merges a sweeping field of view with an ultra-fast f/1.4 maximum aperture. Despite its high-speed optics, this lens breaks boundaries with an incredibly lightweight and minimalist footprint. It serves as an ultimate, high-performance tool for landscape shooters, architectural and real estate photographers, content creators, and astrophotographers looking to capture crisp, star-filled night skies without the bulk of a heavy kit.

Elite Optical Speed & Astrophotography Performance
Bright f/1.4 Maximum Aperture: The wide-open f/1.4 threshold excels in low-light environments and grants unique shallow depth-of-field control over an ultra-wide canvas, yielding smooth, isolated subjects.

Coma Flare & Distortion Suppression: The optical formula is specifically optimized to eliminate sagittal coma flare and peripheral aberrations. Stars and points of light remain perfectly round dots all the way to the extreme corners of the frame—even when shooting wide open at f/1.4.

Premium Glass Matrix: Integrates advanced FLD (F Low Dispersion) and SLD (Special Low Dispersion) glass elements to systematically neutralize chromatic aberrations and secure high color fidelity.

Three Double-Sided Aspherical Elements: Precision-engineered to minimize geometric distortion and spherical aberrations, maintaining uniform center-to-edge sharpness while enabling a highly compact internal optical layout.

Anti-Reflective Flare Control: Internal ghosting and surface reflections are aggressively managed, preserving deep image contrast and color neutrality when shooting directly into harsh sunlight or strong artificial backlighting.

9-Blade Rounded Diaphragm: Outfitted with a rounded nine-blade aperture system to produce a smooth, circular, and organic background blur (bokeh) quality.

Ultra-Compact Architecture & Gimbal Stability
Minimalist, Pocketable Footprint: Measuring a mere 2.6 inches in length and weighing just 8 ounces, this lens is 30% shorter and 50% lighter than legacy wide options like the Sigma 16mm f/1.4 DC Contemporary.

Optimized for Vlogging & Gimbals: The featherweight, balanced design places no strain on compact 3-axis motorized gimbals or mirrorless camera bodies, making it a dream option for handheld travel vlogging, run-and-gun filmmaking, and street documentary work.

Quiet Stepping Motor AF: Equipped with a rapid stepping autofocus motor that delivers quick, dead-accurate, and near-silent focusing performance for both stills and video tracking.

Controlled Focus Breathing: Engineered to minimize focus breathing, ensuring the wide-angle frame boundaries remain rock-steady and consistent when pulling focus between close-up and distant subjects.

Tactile Handling & Rugged Weather Sealing
Dedicated Manual Aperture Ring: Features a physical aperture ring on the lens barrel for direct, mechanical exposure adjustments. It includes a clickable “A” (Auto) position lock to instantly transfer aperture management back to the camera body’s electronic dials.

Dust & Splashproof Gasketing: Built with weather-resistant sealing around critical joints to protect internal electronics when shooting out in demanding outdoor climates and inclement weather.

Oleophobic Front Coating: The front objective glass features a specialized water- and oil-repellent coating that actively resists raindrops, dust, and smudges, allowing for effortless cleaning in the field.

Unified Ecosystem Fit: Perfectly color-matched and sized to sit alongside Sigma’s wider family of f/1.4 DC DN Contemporary primes, providing filmmakers with a consistent look, filter capability, and physical balance across multiple focal lengths.

Included Accessories
Dedicated Petal Lens Hood Included: Ships complete with its original matching petal-shaped lens hood, engineered to block off-axis stray light from causing flare while acting as a robust bumper against accidental front impacts.

Front & Rear Caps Included: Includes both the front and rear lens caps to safeguard the glass elements from dust, fingerprints, and smudges during storage or travel.
