SIGMA 30mm F1.4 DC DN ? Contemporary
High optical performance in a
Compact target. The new standard F1.4 lens for cameras without
APS-C format mirror.
The Grand Opening Standard Objective 30mm
F1.4 DC DN Contemporary gives the opportunity to the possessors
of cameras without mirror to experience the fun of photographing
large openings, with luminosity F1.4. Photographers will enjoy
an attractive bokeh effect that only the goals of great opening
can offer, and the exceptional optical definition to be expected
of a high quality fixed focal point. Taking advantage of the latest
technologies and design ideas SIGMA, this new goal meets
the concept of the Contemporary line, which offers an optimal balance
several elements. Photographers can feel the experience of a
F1.4 luminosity and functionality of a standard target with a
focal length equivalent to 35 mm of 60 mm in the Micro Four system
Surfaces and 45 mm in the Sony E-mount and Canon EF-M system.
Image quality that rivals with
our line of objectives Art
In addition to having an energy design and distribution
optimized, this objective incorporates an aspheric element and an element
double aspheric, as well as an element with a high refractive index,
high dispersion glass with a high partial anomalous dispersion.
By effectively harnessing these technologies, the objective offers a
excellent luminosity to the edges of the image and reduces to the minimum
transversal aberration. To correct the distortion, the
objective takes advantage of the image correction of the camera body without
mirror, using the correction power of the optical system to improve
the sharpness. The end result is an extremely compact target
which offers an image quality that rivals ours
objectives of the Art line. ”
More compact structure and
improved performance thanks to the use of TSC
The SIGMA 30mm F1.4 DC DN ???
Contemporary has a barrel and TSC opening pieces, which
contribute to both the compact size of the target and the good
operation of the opening system. The TSC helps increase the
accuracy of cells holding the elements of the target and
parts related to the focus lens group, further improving
plus target performance. *Thermally Stable Composite (TSC) is
a material that offers similar thermal expansion characteristics
Aluminum. As the parts made with TSC expand and
contract less for temperature changes, help keep the
target performance. The TSC also offers an exceptional
elasticity. Compared to polycarbonate containing 20%
glass, the TSC offers approximately 70% more elasticity. In
compared to the polycarbonate containing 30% glass, the TSC
offers approximately 25% more elasticity. (Comparation between
components produced by SIGMA).
Compact size combination and
excellent optical performance
For optimal balance of light, with compact chamber bodies
with a short posterior focal distance, SIGMA has designed the new
objective SIGMA 30mm F1.4 DC DN ???
Contemporary to be extremely compact. In addition, it has
technology SIGMA of internal focus and lighter elements in the
focus lens group, which make possible a more final size
compact, very useful for taking videos. Structurally,
target incorporates materials and pieces that contribute to their size
compact and lightweight. In short, this is an objective without
combined with exceptional optical performance
excellent portability and ease of handling “.
