overview - Designed for full-frame Leica L-mount mirrorless cameras, the fast and versatile Sigma 45mm f/2.8 DG DN Contemporary Lens is a normal-length prime that optimizes 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 utilizing 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. - Key Features L-Mount Lens/Full-Frame Format Aperture Range: f/2.8 to f/22 Soft, Smooth, Rounded Bokeh High-Speed AF with Stepping Motor Rounded 7-Blade Diaphragm Durable, Weather-Sealed Construction - In the Box Sigma 45mm f/2.8 DG DN Contemporary Lens for Leica L LH577-01 Lens Hood Sigma LCF-55 III 55mm Lens Cap LCR II Rear Lens Cap
