The fast and versatile Sigma 45mm f/2.8 DG DN Contemporary Lens is a normal-length prime that optimizes size as well as a 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. 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. Created for full-frame Leica L-mount mirrorless cameras, this prime, normal-length lens is designed to deliver excellent image quality while optimizing size and weight. It is also suitable for APS-C models where it provides a 68mm equivalent focal length. Constant f/2.8 maximum aperture is well-suited for working in available light conditions and provides greater control over the depth of field. 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.
