Refined Optics

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.

The lens is constructed with one SLD glass element and one FLD glass element to correct chromatic aberration.

It incorporates three high-precision aspherical elements, which reduces the total size and weight of the lens.

Physical Design

I-series lens emphasising a sleek and stylish physical design 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.

Wide-angle 20mm lens designed for full-frame Leica L-mount mirrorless cameras, however, can also be used with APS-C models where it provides a 30mm equivalent focal length.

Bright f/2 maximum aperture strikes and ideal balance between speed and size and manages to maintain a compact physical profile while also offering low-light performance and depth of field control. Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.

Fast Closeup Focusing

Integrated stepping motor realises smooth and quiet autofocus.

Full-time manual focus control can also be selected via an arc-type auto/manual focus switch. A newly designed linear/non-linear manual focus function is also available. Minimum focusing distance of 8.7" for unique close-up shooting capabilities.

All-Purpose Functionality

All-metal body and high-precision metal parts with a dust- and moisture-resistant lens mount for increased protection from the elements. Metal lens hood helps to reduce lens flare when working in strong lighting conditions and also offers some protection to the front element of the lens.

Compatible with optional CH-11 Magnetic Cap Holder, which features a mini-carabiner for clipping to a bag, jacket, or belt loop.
