![]() ![]() Often one lens will perform better at a particular focal length and aperture, while the other will perform better at other focal length and aperture combinations.Įven at the same focal length and aperture, one may be sharper at the center but not as sharp at the edges as the other lens. Sigma 18-50mm f/2.Comparing two very similar lenses like the Sigma 18-50mm f/2.8 EX DC Macro and the Tamron 17-50mm f2.8 SP XR Di II LD VC Lens in terms of sharpness can be difficult.Sigma 56mm f/1.4 DC DN: BHphoto / AmazonUS / Adorama. ![]() Sigma 30mm f/1.4 DC DN: BHphoto / AmazonUS / Adorama.Sigma 16mm f/1.4 DC DN: BHphoto / AmazonUS / Adorama.Rounded seven-blade diaphragm contributes to a pleasing bokeh quality. 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. Standard zoom lens is designed for Fuji X-mount cameras and provides a 27-75mm equivalent focal length range.Ĭonstant 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. 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. 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. 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 Fuji 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. 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. ![]()
