Product Description
THE BOKEH MASTER
Outstanding wide-aperture, mid-telephoto performance with F1.4 brightness at
maximum aperture, this lens incorporates 17 optical elements in 12 groups, an
uncommonly large number of elements for a prime lens. By including three FLD
glass elements, two SLD glass elements, and one aspherical lens element, the
optical system minimizes axial chromatic aberration to deliver extremely high
resolution along with ample peripheral light volume.
Like SIGMAs Sports line lenses, the 105mm F1.4 DG HSM Art features a highly
effective dust- and splash-proof structure with special sealing at the mount
connection (with exception of the Sigma mount), manual focus ring, cover
connection, and other areas, allowing photographers to work in all types of
weather. In addition, the front of the lens is protected by a water- and
oil-repellent coating that makes cleaning easy.
Instead of conventional ABS plastic, the exclusive lens hood features CFRP
(carbon fiber reinforced plastic), a light but strong material used in the
interior and exterior fittings of aircraft, among many other applications. The
removable Arca-Swiss tripod socket is compatible with Arca-Swiss platform and
clamps, and its exclusive protective cover makes the lens easier to carry and
use when shooting hand-held.
