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. 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. The lens design includes three high-precision glass-molded
aspherical elements coupled with a special low dispersion element. Together
they minimize the total number of elements for superb optical quality without
excessive weight. 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. 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.
Standard zoom lens is
designed for APS-C-format FUJIFILM X-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.
