(Refurbished Excellent) Sigma 45mm f/2.8 DG DN | Contemporary - L-mount Camera Lens

The Sigma 45 mm f/2.8 DG DN | Contemporary is a versatile and lightweight fixed-focal-length prime lens designed for L-mount full-frame mirrorless cameras from Panasonic, Leica, and Sigma. It delivers a classic 45 mm perspective (close to a natural field of view on full-frame), making it ideal for street, environmental portraits, travel, documentary, and everyday photography.

Built with eight optical elements in seven groups and a rounded seven-blade diaphragm, this lens produces sharp, high-contrast images with pleasing out-of-focus rendering and smooth bokeh. Its f/2.8 maximum aperture provides good performance in varied lighting while keeping the lens compact.

The lens features fast, quiet autofocus suitable for stills and video, and supports DMF (Direct Manual Focus) and AF+MF focus modes for intuitive control. Its dust- and splash-resistant mount helps protect against the elements when shooting outdoors.

Despite its robust build, the Sigma 45 mm f/2.8 remains lightweight at about 215 g (L-mount) with a compact form (≈64.0 mm diameter × 46.2 mm length), making it excellent for on-the-go shooting and travel. It accepts 55 mm front filters, and includes practical accessories like a lens hood and caps in the box.

Overall, this Contemporary-line 45 mm lens strikes an ideal balance between image quality, portability, and usability, offering a flexible everyday prime that complements a wide range of shooting styles and mirrorless bodies.
