The Leica L-mount 35mm f/2 DG DN Contemporary Lens from Sigma is a sleek wide-angle prime pairing a bright design with a portable form factor. 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 Wide-angle 35mm lens is designed for full-frame Leica L-mount mirrorless cameras, however, it can also be used with APS-C models where it provides a 52.5mm equivalent focal length. Bright f/2 maximum aperture strikes an 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. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. The 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. This lens is compatible with the optional Sigma UD-11 USB Dock for fine-tuning different lens characteristics and updating its firmware.
