Offering best-in-class optical performance, this lens is designed
to minimise aberrations for images virtually free of streaking
and warping.
SIGMA has a proven reputation for wide-angle lens design and
manufacturing. Drawing on this experience and design know-how,
refined through development of the SIGMA 35mm F1.4 DG HSM | Art
and 50mm F1.4 DG HSM | Art in our Art line, we have successfully
minimised sagittal coma flare, chromatic aberration, distortion,
and vignetting to achieve exceptional levels of optical
performance with almost no aberration or distortion. This lens
provides the best possible performance when photographing a
variety of subjects from cityscapes, ain ranges, and the
star-filled night sky to indoor photography with low illumination
or scenes that require a smooth bokeh effect. Enjoy the
astonishing optical performance of the new F1.4 series that has
just joined SIGMA's iconic Art line.
This lens features minimised aberration achieved through the
latest design technology and know-how that has been accumulated
by SIGMA in its lens development over many years and offers
astonishing rendering performance, even at the edges, with
ultra-high resolution. Whilst featuring higher resolution around
the focus point, the lens offers a smooth and natural bokeh
effect. Both high definition rendering without chromatic
aberration and natural bokeh expression are possible, even at
maximum aperture.
Sagittal coma flare is the aberration in which a point light
source appears as a streak instead of a point, and it affects
large-diameter lenses in particular. By positioning aspherical
lens elements toward the rear of the 24mm F1.4 DG HSM | Art, we
have adjusted the angle of incidence of light for optimal power
distribution. Even at wide-open aperture, you will enjoy
outstanding image quality. Since streaking of point light sources
toward the edges of the image is minimized, this lens is a
powerful ally in photographing celestial bodies, night time
illumination, and more.
FLD,SLD and Aspherical lens elements
The 24mm F1.4 DG HSM | Art incorporates FLD ("F" Low Dispersion)
glass and SLD (Special Low Dispersion) glass elements to minimise
chromatic aberration of magnification, which is mainly visible
around the edge of the image. The result is high image quality
throughout the entire focusing range-sharp and high-contrast
image rendering without colour blur.
Improving efficiency at large apertures and minimising
vignetting, we have designed the lens to secure very good
brightness. Even at open aperture, it ensures high-contrast
images for indoor photography, astronomical photography, and when
photographing blue sky.
When photographing with point light sources such as electric
lights or reflections on a body of water in the background, the
rounded 9-blade diaphragm helps produce an attractive bokeh
effect-even at large-aperture settings.
HSM (Hyper Sonic Motor)
HSM (Hyper Sonic Motor) delivers high AF speed and extremely
quiet performance. SIGMA's latest AF algorithm makes possible
even smoother automatic focusing. After AF has done its job,
fulltime MF (manual focus) allows you to make fine adjustments to
focus simply by turning the focus ring. Using the SIGMA USB DOCK
(sold separately) allows you to access the MO (manual override)
function, which allows you to manually focus at any time during
AF by turning the focus ring.
TSC (Thermally Stable Composite)
Conventionally it is considered essential to leverage the
qualities of metal and polycarbonate in camera and lens layout
design. A first for the industry, the barrel of the new series of
SIGMA lenses features a new TSC (Thermally Stable Composite) that
offers minimal thermal shrinkage combined with exceptional
hardness. It also offers 25% greater elasticity than
polycarbonate. Since its thermal shrinkage is low, TSC matches
well with metal parts, further contributing to the high-precision
construction of the lens.
