Versatile Standard Zoom Lens

The Sigma 18-50mm f/2.8 DC DN Contemporary Lens is perfect for a range of photo and video applications, including landscapes, portraits, street photography, architecture, and events. This Sony E-mount lens offers a full-frame equivalent zoom range of 27-75mm and a constant aperture of f/2.8 throughout the zoom range. It features three high-precision glass-molded aspherical elements and a special low dispersion element, which minimises the total number of elements for superb optical quality. Autofocus is fast and quiet thanks to the lens's stepping motor, making it ideal for shooting video or fast-moving subjects. Plus, it has a minimum focusing distance of 4.8", so it can be used for close-up photography and a rounded seven-blade diaphragm for a beautiful bokeh quality.

• Standard zoom lens is designed for APS-C-format Sony E-mount cameras and provides a 35mm equivalent focal length range of 27-75mm.
• 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.
• 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.
• Special Low Dispersion (SLD) element reduces chromatic aberrations and color fringing.
• Super Multi-Layer Coating minimizes flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.
• 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.
• Minimum focusing distance of 4.8" and a 1:2.8 maximum magnification ratio benefits working with close-up subjects.
• Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
