Sigma 18-50mm f/2.8 DC DN Contemporary Lens - Leica L-Mount is a small, light, and bright standard zoom for crop-sensor mirrorless cameras. This lens delivers a versatile full-frame equivalent zoom range of 27-75mm and a wide constant aperture of f/2.8 throughout the entire zoom range. An ultimate workhorse, the lens features a minimum focusing distance of just 4.8", enabling it to be used for macro-style close-up photography, and the lens is also outfitted with a rounded seven-blade diaphragm for a pleasing bokeh quality. The lens design includes three high-precision glass-molded aspherical elements coupled with a special low dispersion element. Together they minimise the total number of elements for excellent optical quality without excessive weight. The Autofocus is exceptionally fast and quiet thanks to the lens's stepping motor, which can be particularly useful when shooting video or fast-moving subjects such as children and animals.

Great Optical Design

Featuring Super Multi-Layer Coating, it minimises flare and ghosting for improved contrast and colour accuracy when working in strong lighting environments. The Special Low Dispersion (SLD) element reduces chromatic aberrations and colour fringing. The three high-precision glass-molded aspherical elements are used to help limit distortion and spherical aberrations and contribute to greater overall sharpness and accurate rendering.

Remarkable Performance

The constant f/2.8 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques. In-camera aberration correction further eliminates optical imperfections such as distortion and vignetting. Stepping motor with nearly silent autofocus that makes it perfectly suited to a range of photographic applications, including shooting in quiet environments, recording videos, and capturing fast-moving subjects.
