Sigma 30mm f/1.4 DC DN Contemporary Lens (Canon RF)
Ultra-Fast, Compact Standard Prime for APS-C Mirrorless Systems

The Sigma 30mm f/1.4 DC DN Contemporary brings Sigma’s highly acclaimed crop-sensor prime lens lineup natively to the Canon RF mount. Offering a highly versatile 48mm equivalent focal length in 35mm terms, this lens delivers a natural standard perspective that closely mirrors the human eye. It serves as an exceptional everyday walkaround prime for street photography, environmental portraits, travel documentation, and low-light videography.

Tailored explicitly for the unique requirements of compact mirrorless systems, this lens masterfully balances outstanding optical sharpness with a lightweight, portable footprint. By combining a blazing-fast f/1.4 maximum aperture with advanced thermal stability and a near-silent stepping motor, the 30mm f/1.4 DC DN enables creators to confidently isolate subjects, produce smooth background blur, and maintain quick focus locks in any shooting environment.

Key Features & Material Innovation

Ultra-Fast f/1.4 Aperture Speed: The bright f/1.4 maximum aperture delivers exceptional ambient light-gathering capabilities, enabling sharp handheld captures at lower ISO settings while providing superior depth-of-field control to beautifully isolate your subject.

Thermally Stable Composite (TSC) Body: Constructed using specialized TSC materials within the internal architecture. This composite offers superior structural elasticity and performance compared to traditional aluminum, minimizing barrel deformation and ensuring high-precision alignment across extreme temperature fluctuations.

Rounded 9-Blade Diaphragm: Outfitted with a 9-blade circular aperture array that produces a remarkably smooth, natural-looking out-of-focus quality (bokeh) with gentle highlight roll-off.

Super Multi-Layer Coating Shield: Individual glass components feature Sigma’s advanced multi-layer coating matrix to suppress surface reflections, ghosting, and internal lens flare, maintaining rich contrast and color neutrality in heavily backlit scenarios.

In-Camera Aberration Correction Support: Fully compatible with digital correction profiles on supported Canon cameras, enabling automatic real-time adjustments for peripheral illumination, chromatic aberrations, and geometric distortion.

Rugged Dust and Splash-Resistant Brass Mount: Features a high-precision, treated brass bayonet mount outfitted with a specialized rubber sealing gasket. This protective barrier blocks dust, moisture, and fine environmental spray from entering the lens housing or the camera’s sensor chamber.

Quiet and Fast Stepping AF Motor: Driven by an optimized internal stepping autofocus motor that delivers quick, smooth, and near-silent focus acquisition. This responsive tracking system makes the lens equally well-suited for static high-resolution stills and fluid video tracking.
