Product description for Sigma AF 85mm f / 1.4 DG DN ART L-Mount / Sony-E 

A new chapter in the Art product line in the age of mirrorless cameras.
Bright, unparalleled optical performance, compact and lightweight, and high-speed AF x {2500} in your hand.

The 85mm F1.4 DG DN | Art combines the fine and precise imaging performance that is essential for portraits with an impressive bokeh that can only be achieved by lenses with a speed of F1.4. The design of the 85mm F1.4 DG DN | Art impresses with its low weight and compact housing and defies the usual conventions. The level of performance and functionality of this lens are a benchmark for successful portraits, which will convince hobby and professional photographers alike.

The slight telephoto focal length of 85mm and the impressive F1.4 bokeh ensure a sharp, clearly exposed motif against a velvety background, which is important for a successful portrait image. In addition, the fast and reliable AF supports the photographer in his work. The compact housing is packed with extensive functions, is dust and splash-proof and is of excellent processing quality.

SIGMAs 85mm F1.4 DG DN | Art can be seen as the new "ultimate portrait lens" for the age of mirrorless cameras. With this 85mm F1.4 lens, SIGMA ensures everyday life full of new possibilities.

1.
Record breaking performance that goes by the name 85mm F1.4 | Kind of earned
85mm F1.4 is basically synonymous with a portrait lens. With the Art product line, SIGMA has committed itself to the highest possible optical performance. In order to implement this project, SIGMA makes use of the latest technologies in the field of optical design as well as the production technologies of the Aizu factory, SIGMA's sole production location, for the development of these lenses. The result is an absolutely detailed picture, which is important for portrait photography and will satisfy amateurs as well as professionals.

The 85mm F1.4 DG DN | Art is equipped with the latest glass with a high refractive index, which, in addition to no less than five SLD glass elements (Special Low Dispersion) and an aspherical lens, ensures the complete correction of aberrations that cannot be eliminated by the correction function of the camera. Special emphasis was placed on the correction of longitudinal color errors, so that photographers will be delighted with sharp images without color fringes - and that already with F1.4. The high resolution from the center to the edges ensures sharpness in the focus area, the F1.4 open aperture for impressive bokeh, which in total brings out the motif in an impressive way.

Repeatedly running through ray simulations as well as repeated practical tests lead to the result that the 85mm F1.4 DG DN | Art efficiently minimizes ghosting and delivers clear, sharp images even when backlit. In order to realize their artistic visions, photographers can take pictures with an aperture of F1.4 without having to worry about the image quality. You can therefore concentrate fully on operating the camera. The new lens undoubtedly delivers a high level of optical performance and lives up to the designation 85mm F1.4 Art.

2.
Light and compact - F1.4 in a new dimension
The 85mm F1.4 DG DN | Art was developed exclusively for mirrorless cameras and weighs just 630g with a filter diameter of 77mm and a housing length of 94.1mm (L) & 96,1(Sony) It has a large lens diameter and excellent optical performance.
Still, it has a lightweight and compact body - a combination that has been difficult to achieve for a long time.

The AF system uses a stepper motor that is optimized for both phase AF and contrast AF. In this way, not only are pictures taken smoothly via face / eye detection AF, but the lens housing is also narrower, because a focusing lens that fits a stepper motor can be made smaller.

In addition, by making optimal use of the camera's internal aberration correction functions, SIGMA was able to concentrate on correcting the aberrations, which can only be eliminated by the optical system, making the lens even smaller. Thanks to this light and compact housing, photographers can use the bright 85mm F1.4 lens in everyday life, such as for snapshots. The 85mm F1.4 DG DN | Art invites photographers to take pictures in a highly unconventional way.

A multitude of functions and excellent workmanship
Despite its small size, this compact lens has extensive functions that will delight both the ambitious amateur photographer and the professional photographer. The 85mm F1.4 DG DN | Art has the new aperture ring lock switch. This prevents unintentional operation of the aperture ring during the exposure. The focus mode switch on the lens housing and the AFL button *, to which functions selected on the camera side can be assigned, also support the photographer when taking pictures.

In addition to dust and splash protection, high-quality materials such as aluminum and TSC (Thermally Stable Composite) are used in predestined locations for this lens, so that a performance level worthy of the Art product line is achieved. In addition to the durability of the housing, the feel and operation were also in the foreground, such as the gentle movements of each individual ring and switch. The 85mm F1.4 DG DN | Art ensures smooth recordings in every sit
