The Sigma 30mm f/1.4 DC DN Contemporary Lens is a fast and adaptable prime lens specifically engineered for APS-C-format Sony E-mount mirrorless cameras. Its bright f/1.4 maximum aperture is advantageous for low-light photography and provides significant control over depth of field, enabling the use of selective focus techniques. The lens's optical construction includes two aspherical elements and one high-refractive index element, which effectively minimizes spherical aberrations and distortion, resulting in enhanced clarity and sharpness in image quality. Furthermore, a Super Multi-Layer Coating has been applied to mitigate lens flare and ghosting in challenging lighting situations. This compact prime lens is also equipped with a stepping autofocus motor, ensuring smooth and nearly silent autofocus performance, making it suitable for both still photography and video recording. Additionally, a rubber seal at the lens mount offers protection against dust and other environmental factors.

• As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance, and meshes a compact, lightweight build and versatile handling with notable optical attributes.
