Key Features & Engineering
Versatile 45mm Equivalent Perspective: Provides a natural standard field of view on APS-C sensors, mimicking the human eye’s perspective for outstanding compositions across various shooting genres.

Ultra-Fast f/1.4 Aperture: The wide f/1.4 maximum aperture affords superior light gathering in low-light conditions and allows for extensive control over shallow depth of field and selective focus techniques.

Advanced Optical Configuration: Features two aspherical elements and one high-refractive index element to drastically curb geometric distortion and spherical aberrations, ensuring high clarity, definitions, and sharp imagery.

Super Multi-Layer Coating: Individual glass elements are treated with Sigma’s Super Multi-Layer Coating to significantly minimize lens flare and ghosting, maintaining contrast-rich and color-neutral performance in heavy backlighting.

Smooth Stepping AF Motor: Outfitted with a high-speed stepping autofocus motor that delivers quick, pinpoint, and near-silent focusing performance, making it highly optimized for tracking subjects during video capture.

TSC Chassis & Brass Bayonet Mount: Built using a specialized Thermally Stable Composite (TSC) material for structural precision across extreme temperature variations. Features a rugged brass bayonet mount with a rubber sealing gasket to guard the camera sensor against dust and moisture.

9-Blade Rounded Diaphragm: Outfitted with a rounded nine-blade aperture structure that yields a creamy, smooth out-of-focus background blur (bokeh).
