8/27/2023 0 Comments Sigma 18 50mm f 2.8Autofocus 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. Together they minimize the total number of elements for superb optical quality without excessive weight. The lens design includes three high-precision glass-molded aspherical elements coupled with a special low dispersion element. ![]() Offered here with a Sony E-mount, this lens provides a versatile full-frame equivalent zoom range of 27-75mm and a wide constant aperture of f/2.8 throughout the entire zoom range. Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.Ideal for a wide range of photo and video applications including landscapes, portraits, street photography, architecture, and events, the 18-50mm f/2.8 DC DN Contemporary Lens from Sigma is a small, light, and bright standard zoom for crop-sensor mirrorless cameras.Minimum focusing distance of 4.8" and a 1:2.8 maximum magnification ratio benefits working with close-up subjects.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.In-camera aberration correction further eliminates optical imperfections such as distortion and vignetting.Super Multi-Layer Coating minimizes flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.Special Low Dispersion (SLD) element reduces chromatic aberrations and color fringing.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.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.Standard zoom lens is designed for APS-C-format FUJIFILM X-mount cameras and provides a 35mm equivalent focal length range of 27-75mm.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. ![]() Offered here with a FUJIFILM X-mount, this lens provides a versatile full-frame equivalent zoom range of 27-75mm and a wide constant aperture of f/2.8 throughout the entire zoom range.
