Sigma 35mm f/2 DG DN Contemporary Overview
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.
- 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.
- Wide-angle 35mm lens is designed for full-frame Leica L-mount mirrorless cameras, however can also be used with APS-C models where it provides a 52.5mm 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.
- One Special Low Dispersion (SLD) element markedly reduces chromatic aberrations and color fringing for improved clarity and color accuracy.
- Three aspherical elements help to control distortion and spherical aberrations for a high degree of sharpness and accurate rendering.
- 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.
- 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.
- Included LCF58-01M magnetic lens cap attaches directly to the front of the lens and is compatible with the optional CH-11 Lens Cap Holder.
- This lens is compatible with the optional Sigma UD-11 USB Dock for fine-tuning different lens characteristics and updating its firmware.
