14-24MM F/2.8 DG DN ART OVERVIEW
Created
for full-frame Sony E-mount mirrorless cameras, the Sigma 14-24mm f/2.8 DG DN
Art Lens provides a versatile range of wide-angle focal lengths with excellent
image quality while optimizing size and weight. An
Art-series zoom, this lens is also distinguished by its fast f/2.8 constant
maximum aperture to suit working in available lighting conditions. Featuring a
sophisticated optical design, a series of low dispersion and aspherical
elements is used to minimize both chromatic and spherical aberrations
throughout the zoom range in order to achieve high sharpness, clarity, and
color accuracy. A Super Multi-Layer Coating combined with a Nano Porous Coating
also helps to suppress lens flare and ghosting to a greater degree than
conventional anti-reflective coatings. This helps to more effectively produce
color-accuracy and contrast-rich imagery in a variety of lighting conditions.
Though
full-time manual focus is available, this lens is equipped with a stepping
motor that enables smooth, high-speed autofocusing that is notably quiet whether
utilizing features such as Face/Eye Detection AF or during video shooting. A
built-in Autofocus-Lock (AFL) button can be assigned additional functions to
widen the range of operations available on the lens, while inside, a rounded
11-blade diaphragm improves image quality by helping to create smooth bokeh.
Additionally, a built-in lens hood serves to protect the front element as well
as prevent stray light from causing flare.
- As
part of the Art line within Sigma's Global Vision series, this lens is designed
to achieve truly notable optical performance and is ideally suited for creative
and artistic applications.
- Created
for full-frame Sony E-mount mirrorless cameras, this wide-angle zoom is
designed to deliver excellent image quality while optimizing size and weight.
It is also suitable for APS-C models where it provides a 21-36mm equivalent
focal length range.
- Constant
f/2.8 maximum aperture is well-suited for working in available light conditions
and provides greater control over depth of field.
- Five
Special Low Dispersion (SLD) elements and one F Low Dispersion (FLD) element
markedly reduce chromatic aberrations and color fringing throughout the zoom
range for improved clarity and color accuracy.
- Three
aspherical elements, including a large-diameter aspherical lens, control
spherical aberrations and distortion for increased sharpness and accurate
rendering.
- A
Super Multi-Layer Coating combined with a Nano Porous Coating has been applied
to lens elements in order to minimize lens flare and ghosting to a greater
degree than conventional anti-reflective coatings. The combination of these
coatings produces contrast-rich and color-neutral imagery, and help to make the
lens even more effective in backlit conditions.
- A
stepping AF motor benefits both photographers and videographers with its fast,
precise, and near-silent performance. Full-time manual focus control can also
be selected.
- Built-in
Autofocus-Lock (AFL) button can be assigned additional functions widens the
range of operations available on the lens.
- Rounded
eleven-blade diaphragm contributes to a smooth and pleasing bokeh quality.
- Front
lens element has been treated with a water- and oil-repellent coating to
benefit working in harsh environmental conditions.
- Included
rear filter holder is equipped with a fall-prevention lock for attaching and
securing gel filters along the lens mount.
- Weather-resistant
construction with a brass bayonet that affords improved mounting accuracy and
rigidity.
