Sigma 45mm f/2.8 DG DN Contemporary Lens
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.
Constant f/2.8 maximum aperture
The constant f/2.8 maximum aperture is well-suited for working in available light conditions and provides greater control over depth of field.
High-speed, quiet AF
Although this lens offers full-time manual focus, it is also equipped with a stepping motor that enables smooth, high-speed autofocusing that is notably quiet, providing a fast and precise performance.
Optical design controls spherical aberrations to help endure large, soft, rounded bokeh while enhancing the three-dimensional impression of the subject. A rounded seven blade diaphragm also contributes to the smooth bokeh.
The bayonet mount is constructed from brass for ensured accuracy and durability. In addition, rubber sealing is incorporated in the mount design, making it both dust and splash-resistant.
