• 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.
• I-series lens emphasizes a sleek and stylish physical design that is built to the same operational standards of Sigma's Cine lenses, including a mechanical aperture ring, knurled metal components, and various switches and tactile controls for intuitive operation.
• Short-telephoto 90mm lens is designed for full-frame Leica L-mount mirrorless cameras, however, can also be used with APS-C models where it provides a 135mm equivalent focal length.
• Five Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing for improved clarity and color accuracy.
• One aspherical element helps to control distortion and spherical aberrations for a high degree of sharpness and accurate rendering.
• Integrated stepping motor realizes smooth and quiet autofocus, which is further complemented by an internal focusing design to promote greater responsiveness.
• Manual aperture ring includes an 'A' position for camera-based aperture selection.
• Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
• Brass bayonet affords improved mounting accuracy and rigidity and rubber sealing is incorporated in the mount's design to render it dust- and splash-resistant.
