Sigma 45mm f2.8 DG DN | Contemporary | Sony E Fit

Designed for combination with relatively small full-frame mirrorless cameras, this standard lens pursues easy operability as a regular prime lens by balancing its easy-to-carry size and high optical performance, thereby embodying the Contemporary line’s development concept of “pursuing optimum balance,” and becoming the perfect first lens in the lineup dedicated for full-frame mirrorless cameras.

The fast and versatile Sigma 45mm f/2.8 DG DN Contemporary Lens is a normal-length prime that optimises size as well as weight while rendering notably smooth bokeh with rounded out-of-focus highlights in both the foreground and background. Coupled with its ability to soften the periphery of blurred images while enhancing the three-dimensional impression of an object, its 9.5" minimum focusing distance makes it suitable for snapshots to tabletop photos, or any imagery where you wish to make your subject stand out.

Though full-time manual focus is available, this lens is equipped with a stepping motor that enables smooth, high-speed autofocusing that is notably quiet whether utilising features such as Face/Eye Detection AF or during video shooting. A rounded seven-blade diaphragm contributes to the smooth bokeh, and a lens hood is included, which can protect the front element as well as prevent stray light from causing flare.

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.

Created for full-frame Sony E-mount mirrorless cameras

(This prime, normal-length lens is designed to deliver excellent image quality while optimising size and weight. It is also suitable for APS-C models where it provides a 68mm equivalent focal length).

Optical design controls spherical aberrations to help endure large, soft, rounded bokeh while enhancing the three-dimensional impression of the subject.

Constant f/2.8 maximum aperture is well-suited for working in available light conditions and provides greater control over depth of field.

A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance. Full-time manual focus control can also be selected.

Rounded seven-blade diaphragm contributes to a smooth and pleasing bokeh quality.

The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
