Optics SIGMA 28-70 F2.8 DG DN (C) E-MOUNT - Description
The SIGMA 28-70mm F2.8 DG DN
Contemporary redefines standard zoom for cameras without mirror
by combining exceptional optical performance,
constant opening of f2.8 and a light and compact body. The design of
28-70mm F2.8 DG DN ? Contemporary is based on the 24-70mm F2.8 DG DN
? Art, but with a focal range from 28 millimeters, making
the body is significantly smaller and lighter while maintaining
excellent optical performance. It is the smallest and lightest zoom of your
class*. Remaining faithful to the central concept of the Contemporary line
to maintain an optimal balance between optical quality and size,
this new optic offers professional quality results in a body
small enough to carry it all over. Besides
prioritizing portability, optical engineers SIGMA have
introduced a new combination of coatings and elements
structural that make this standard zoom well equipped for
use in a wide variety of shooting environments. Likewise,
the latest production and manufacturing techniques for
ensure exceptionally high construction quality. The
28-70mm F2.8 DG DN ? Contemporary incorporates the mirrorless range SIGMA other bright zoom lens, high performance and great opening,
offering a more compact alternative to the existing 24-70mm F2.8 DG DN
? Art.

Design based on the Art line SIGMA, with the same optical performance
The optical design of the SIGMA 28-70mm F2.8 DG DN ? Contemporary is based on
the 24-70mm F2.8 DG DN ? Art, known for its excellent performance
optical in its entire zoom range. Faithful to the central concept of the line
Contemporary, 28-70mm F2.8 DG DN ? Contemporary has developed
to provide an appropriate balance of performance and portability, and
as such, this high opening standard zoom offers a quality of
exceptional image that rivals the Art line optics for the
daily use. Based on cutting edge technology, 28-70mm F2.8 DG
DN ? Contemporary has an advanced optical design that includes three
aspherical elements, two FLDs and two SLD elements. Despite using
less total elements than the 24-70mm F2.8 DG DN ? Art, its design
offers a complete correction of axial aberration and
aberration of the sagital coma, aberrations that cannot be corrected
the camera, which allows users to create images that are
evenly sharp from the center to the edges of the frame. His
design prevents ghost images (ghosting), and the use of
Super Multilayer and Nanoporous coatings minimizes flashes and
allows to offer high contrast results in conditions of
counterlight. It also has a coating to repel water and
oil on the front of the optic. The SIGMA 28-70mm F2.8 DG DN
??? Contemporary combines all key optical features
required by a high opening standard zoom, which are essential
to photograph a wide variety of topics under firing conditions
Very different. With the addition of the new 28-70mm F2.8 DG DN ?
Contemporary, SIGMA now offers two optimal zoom solutions
standard f2.8 for mirrorless cameras. The new 28-70 mm F2.8 DG DN ?
Contemporary achieves a remarkable portability and offers the same
optical performance that the already existing 24-70mm F2.8 DG DN ? Art, for
professional use and with the highest performance levels throughout
of all its rank focal.sigma-28-70-dg-dn-contemporary-3
A light and compact body, ideal
for daily use
By being slightly less angular than the 24-70mm F2.8 DG DN
IVA Art, it has been possible to significantly reduce the size of
28-70mm F2.8 DG DN ? Contemporary. To adapt it to the concept
Contemporary line design, which balances performance with
portability, the new zoom has a simpler structure to
dust test and splashes, and smaller switches. This
makes it the smallest and lightest zoom of your class.* Incorporated
only light focus element that maintains the compact AF unit,
and this, along with a fast and silent impulse engine, makes the
automatic focus performance is really agile. The 28-70mm
F2.8 DG DN ? Contemporary weighs only 470 grams, and when used with SIGMA fp the set weighs 890 grams. The great portability it offers
a camera system weighing less than 1 kilo provides photographers
a great freedom and flexibility to achieve your creative vision.
It is also a perfect combination for filmmakers looking for a
high performance camera system, lightweight and easy to handle, and
work well with a gimbal and other accessories. A standard zoom

Excellent construction quality
with special attention to detail
Prioritizing to optimal portability, the body of SIGMA 28-70mm
F2.8 DG DN ? Contemporary consists mainly of parts
Light. While it is said to be more difficult to ensure accuracy
processing of plastic parts that metals, has not
there was no sacrifice in the quality of construction of 28-70mm F2.8
DG DN ? Contemporary. The reason is that a
polycarbonate called TSC (Térmicamente Estable), which
has a thermal contraction level comparable to that of aluminum. This
helps to reduce the differences between thermal contraction
metal and non-metallic parts, ensuring stable levels of
performance even in an environment with extreme temperature changes.
The use of polycarbonates in the construction of the zoom rings and
approach can make your operation less effective.
However, with careful treatment in the accuracy of these
parts and adjusting the movement with the right lubricant, the rings
offer precise action with an exceptional high sensation
quality. What allows us to achieve these pieces produced with
precision and a premium aesthetic is the impressive standard of
manufacturing technology and rigorous quality control
carried out in the factory SIGMA aizu, in Japan. The SIGMA 28-70mm
F2.8 DG DN ? Contemporary offers a new photo experience
improved for mirrorless camera users that require a zoom
large opening standard. Your excellent construction makes it so
exciting to use it as it is to see the amazing images that you can
producing, inspiring us to achieve our full potential creativo.sigma-28-70-dg-dn-contemporary-2
