An inherently flexible focal length, 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. The standard wide field of view is useful for a broad array of subject types, including landscape, street, and reportage shooting, and the f/2 maximum aperture excels in challenging lighting and enables greater control over depth of field. In terms of the optical design, three aspherical elements and one SLD element are used to minimize a variety of aberrations and distortion for sharp and accurate rendering. Also, a Super Multi-Layer Coating helps to control ghosting and flare for improved color fidelity and contrast.
In regard to handling and focus, this lens features a stepping motor for quick and quiet AF performance that suits both photo and video applications. As an I Series lens, too, this lens features a manual aperture ring and all-metal barrel constriction for enhanced tactility. Additionally, there is a rounded nine-blade diaphragm for smooth bokeh quality and the lens housing is also weather-sealed to suit working in inclement conditions.
