Speed and Sharpness

• Designed for use with APS-C-format cameras, this lens offers a 22.5mm-equivalent focal length.
• Ultra-wide field of view pairs with a fast f/1.4 maximum aperture to suit working in low-light conditions and for controlling depth of field.
• Optical design includes FLD and SLD glass elements to reduce chromatic aberrations and achieve high color accuracy.

• Three double-sided aspherical elements control distortion and spherical aberrations, as well as help to promote high sharpness and reduce the overall size and weight of the lens.
• Optical design prioritizes edge-to-edge sharpness and reducing sagittal coma flares, even when shooting wide open.
• Lens flare and surface reflections are also well-controlled to suit working in bright, high-contrast environments.
• Rounded 9-blade diaphragm contributes a smooth, rounded bokeh quality.

Compact Creativity

• Compared to the 16mm f/1.4 DC Contemporary, this 15mm f/1.4 is 30% shorter and 50% lighter in weight—this lens measures 2.6" long and weighs about 8 oz, compared to the 16mm f/1.4 that measures over 3.5" long and weighs over 14 oz.
• Suitable for both photo and video recording, the compact, lightweight, and balanced design makes this an ideal option for gimbal-based shooting and vlogging applications.
• Stepping motor delivers quick, quiet, and accurate autofocus performance. Additionally, focus breathing is well-controlled to maintain the field of view while pulling focus.

Durable Design and Handling

• Dust- and splash-resistant design complements working in outdoor and inclement conditions. Additionally, a water- and oil-repellent coating has been applied to the front lens element to resist the elements and make it easier to clean.
• Manual aperture ring for direct, intuitive exposure control; there is also an 'A' position to allow for camera-based aperture control.
• Included petal-shaped lens hood reduces lens flare and protects against accidental bumps.
• Well-matched to other Sigma f/1.4 DC lenses to create a compact system of fast, consistent prime lenses spanning a wide range of focal lengths.
