SIGMA 105mm f/1.4 DG HSM Art Lens for F - Manual (Page 2)

Leading the way in F1.4 brightness
Since introducing its first SIGMA Global Vision F1.4 lens in 2012, the 35mm F1.4 DG HSM | Art,
SIGMA has been adding wide-aperture F1.4 options to the lineup. Now, with the introduction of the
new 105mm F1.4 DG HSM | Art, SIGMA offers a total of nine lenses with F1.4 brightness, including six
for full-frame cameras and three for APS-C cameras. SIGMA has designed all of these lenses to offer
minimal optical aberration and deliver incredible resolution and stunning contrast. Boasting the
longest focal length of the F1.4 Art line lenses, the new lens combines outstanding resolution with a
beautiful bokeh effect. Designed with great care to ensure that both the in-focus and out-of-focus
areas of the photograph are equally satisfying to the eye, this lens is truly a “bokeh master.” The SIGMA
105mm F1.4 DG HSM | Art has earned its place as the flagship of the F1.4 Art line lenses, prioritizing
image quality above all to fulfill the promise of the line, delivering truly amazing optical performance.
Key features
1. Optical system delivering unsurpassed F1.4 performance
In order to combine 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. The area in focus is extremely
sharp, while the area out of focus features a beautiful bokeh effect with highly natural colors, making
this lens a powerful choice for portrait photography. The optical system also minimizes sagittal coma
flare, making this lens excellent for capturing starry skies.
2. Exceptional peripheral brightness
The most effective method of ensuring ample light is to maximize the diameter of the first element of
the optical system. With its large filter diameter of 105mm, the SIGMA 105mm F1.4 DG HSM | Art
delivers a significantly greater volume of peripheral light than other lenses in its class. Minimizing
vignetting while offering a beautiful bokeh effect, this lens is ideal for portrait photography.
