Sigma 50mm f/2 DG DN (C) Lens, Silver (Leica L)

Offering a focal length ideally suited for portraiture, street scenes, and all-purpose shooting, the Sigma 50mm f/2 DG Contemporary Lens delivers sophisticated optical performance and fast autofocus in a compact and lightweight design. One of the most versatile focal lengths available, this 50mm lens pairs its normal field of view with a bright f/2 maximum aperture that strikes a balance between a compact design and low-light performance plus control over depth of field. This combination makes the 50mm f/2 an ideal everyday lens for environmental portraiture and landscapes with a narrow-enough field of view to isolate details and subjects within busy scenes.

• Contemporary Line lens features a compact design that measures approximately 7 x 7cm and a weight of just over 340 grams, making it portable enough for everyday shooting needs without compromising on optics or speed.
• Internal focusing design pairs with a stepping AF motor for responsive and fast focusing performance that's suitable for both stills and video applications.
• Optical design includes one SLD element and three aspherical elements, to optimize sharpness and limit aberrations, and a Super Multi-Layer Coating that controls flare and reflections.
• Rounded 9-blade diaphragm contributes to a smooth and pleasing bokeh quality when employing selective focus techniques.
• Dust and splash-resistant construction with a brass bayonet mount for ensured accuracy and durability.
