Sigma 85mm f1.4 DG DN Art

85mm Art | SIGMA lens SIGMA 85mm for SONY

Large-diameter, unparalleled, compact and lightweight optical performance and high-speed AF – all in hand.

The SIGMA 85mm Art F1.4 DG DN Lens combines clear and delicate rendering performance, which is a requirement for portrait photography, with beautiful, rich bokeh effects that are only possible with lenses like a large-diameter F1.4, at a level that will satisfy both professional and advanced amateur photographers. The focal length of 85 mm and the significant bokeh effect with F1.4 brightness allow users' subjects to stand out in a complementary way, which is one of the essences of taking portrait photographs, so that users can enjoy them to the fullest.

In addition to the fast and constant AF response, the exclusive mirrorless design of the SIGMA Lens 85mm Art F1.4 DG DN | Art has realized a lightweight and compact lens body that defies convention. And its small body is packed with a variety of functionalities, including a dust- and splash-proof structure, backed by excellent build quality.

The 85 mm F1.4 DG DN | Art is SIGMA 's new "ultimate portrait lens" for the mirrorless era. And with it, SIGMA proposes a completely new world of possibilities offered by this "85mm F1.4 lens for everyday use", thanks to an unprecedented level of portability, free of limitations related to size or weight.

[Key Features]

1. Record performance worthy of the name of 85mm F1.4 | Art

Sigma 85mm for SONY and L-mount is an almost synonymous specification of a portrait lens. With the lenses of the Art line, SIGMA pursues the highest possible optical performance and has dedicated the latest optical design technologies, as well as the production technologies of the Aizu factory, the only production site of SIGMA, to the development of these lenses. The result is a detailed image fundamental to portrait photography that is achieved at a level that will satisfy both professional and advanced amateur photographers.

In addition to five SLD (Special Low Dispersion) elements and an aspherical lens, the 85.4 F1.4 DG DN | Art has incorporated the latest high refractive index glass, which works to completely correct aberrations that cannot be handled by the correction function on the camera side. With a particular emphasis on axial chromatic aberration correction, users will enjoy sharp images without color bleeding, up to the maximum aperture of F1.4.

The high resolution power that covers the entire image from the center to the edges ensures the sharpness of the focused area, and together with the significant bokeh effect produced by the F-value of 1.4 highlights the user's subject in an evocative way.

Numerous rounds of ray trace simulation, as well as repeated real-world testing, have given the F1.4 DG DN | 85 mm | Design your ability to minimize ghosting, ensuring clear, crisp images even when shooting in backlight conditions.

With the ability to shoot from the maximum aperture of F1.4 without worrying about image quality, users can focus on camera operations to realize their artistic expressions, such as exposure adjustment and depth of field. This new lens actually offers a level of optical performance truly worthy of the name of 85mm F1.4 Art.

2. Lightweight and compact: a new perception of F1.4

The SIGMA 85mm for SONY and L-mount weighs 630g/22.2oz., with a filter size of 77mm and a body length of 94.1mm/3.7in. *. Designed exclusively for mirrorless cameras, it has a "large lens diameter and excellent optical performance" and "a lightweight, compact body," a combination that has long been difficult to achieve.

The AF motor system employs a stepper motor that is optimized for phase detection AF and contrast AF. Not only does this provide a smooth shooting experience that is only possible with a mirrorless camera, such as face/eye detection AF, but it has also made the lens body much smaller, as the focus lens has been made small to better fit a stepper motor. . In addition, by taking full advantage of the aberration correction functions in the camera, SIGMA was able to concentrate on aberration correction that could be handled by the optical system alone, which further contributed to making the lens smaller in size.

With such a lightweight and small body, users can now pull out a large diameter 85mm F1.4 lens for everyday use, such as taking snapshots. The 85 mm F1.4 DG DN | Art invites users to enjoy photography in an unconventional way.
