85mm F1.4 DG DN

The new gold standard in portrait lenses for mirrorless cameras.

The first ever F1.4 DG DN Art lens is here, marking a new chapter in SIGMA’s mirrorless journey. This stunning, full-frame prime, designed from the ground up specifically for mirrorless cameras, offers unparalleled optical performance, a compact and lightweight body, robust build quality and high-speed AF. A remarkable triumph of optical design and engineering, it promises to be a game-changer for E-mount and L-Mount photographers.

This fully reimagined optic is SIGMA’s vision of the ultimate portrait lens for the mirrorless age, and with it, SIGMA proposes a whole new world of possibilities thanks to the lens’ unprecedented level of portability and quality.

Class-leading image quality

An 85mm focal length and F1.4 aperture are specifications almost synonymous with a professional portrait lens. As with all Art line lenses, SIGMA has pursued the highest possible optical performance and employed the latest design and production technologies at SIGMA’s factory at Aizu, Japan. The optical design of the lens is completely different to the existing 85mm F1.4 DG lens in SIGMA’s current line-up.

In addition to five SLD elements and one aspherical element, the 85mm F1.4 DG DN | Art has incorporated the latest high-refractive-index glass, which works to correct aberrations that cannot be effectively handled by in-camera correction. With a particular emphasis given to the elimination of axial chromatic aberration, users will enjoy sharp images with no color bleeding all the way up to the maximum aperture of F1.4.

The high resolving power across the entire image from the centre to the edges of the frame ensures exceptional sharpness of the in-focus area, and coupled with a very shallow depth-of-field it’s easy to separate the subject from the background for captivating, high-impact portraits.

 Numerous rounds of ray-trace simulations, as well as repeated real-world testing enabled SIGMA’s lens designers to minimise flare and ghosting, which has ensured clear, high-contrast images even when shooting in backlit conditions.

Photographers can work wide open at the maximum aperture of F1.4 with total confidence, allowing them to focus fully on creative decisions such as composition, exposure and depth-of-field. This new 85mm prime delivers a level of optical performance truly worthy of its place in SIGMA’s Art range.

Outstanding sharpness across the frame

The SIGMA 85mm F1.4 DG DN | Art boasts superior image quality to the already brilliant 85mm F1.4 DG HSM | Art atmosphere a fraction of the size and weight.

Exceptionally lightweight and compact

The 85mm F1.4 DG DN | Art weighs in at 630g with a filter size of 77mm and a body length of 94.1mm, making it far smaller and lighter than SIGMA’s original 85mm F1.4 Art lens, which weighs 1,215g*. Designed exclusively for mirrorless cameras, it breaks the usual 85mm F1.4 mould by combining a very large lens diameter, superb optical performance and a lightweight and compact body.

The AF system employs a stepping motor that is optimised for both phase detect and contrast AF. Not only does this provide a smooth shooting experience only possible on a mirrorless camera (such as face/eye AF), but it has reduced the size of the lens body thanks to a much smaller focus element. By making the most of in-camera aberration correction functionalities, SIGMA was able to concentrate on the correction of aberrations that could only be eliminated effectively by the lens’ optics, which further contributed to making the lens smaller. With such a small and lightweight body, users can now take out an ultra-wide aperture 85mm lens for day to day shooting, or carry it around all day at a wedding, without worrying about being weighed down.

Superb build quality and impressive feature set

This compact lens is packed with a range of advanced functionalities that make it well-suited to professional use by both photographers and film makers.

The 85mm F1.4 DG DN | Art has a newly introduced iris ring lock switch, which allows users to lock the iris ring either at auto, or between apertures F1.4-F16. This prevents unintended movement of the ring from auto to manual, or vice versa, during shooting so users can focus on creating their shot. There is a Focus Mode Switch on the lens barrel, and an AFL button that allows various functions to be assigned from the camera body according to user preference*.

In addition to the dust- and splash-proof structure, the 85mm F1.4 DG DN | Art uses materials such as aluminum and TSC (Thermally Stable Composite) to achieve superb Art-line build quality, but with weight kept to a minimum. In addition to the durability of the body, SIGMA’s lens designers have paid particular attention to the experience of using this lens, achieving an ultra-smooth movement on the iris and focus rings, and the precise, easy switch action.

*Limited to compatible cameras.  Also, the functions depend on the camera.

The lens features a switch on the barrel to change between auto and manual focus (①) as well as a customisable AFL switch that can assigned to a particular function via the camera (②). The lens has a manual iris ring that can easily be de-clicked (③) for easier video shooting, and there’s also an iris ring lock switch (④) to stop users accidentally knocking the iris ring from auto to manual and vice versa as they shoot.

The lens features the dust- and splash-proof structure with water- and oil-repellent coating on the frontmost surface of the lens, which supports shooting in various environments.

ESSENTIALS

You'll find our philosophy and craftsmanship in every product

Our new lineup fully expresses our approach to lenses and photography itself. All of our lenses belong to one of three lines—Contemporary, Art, or Sports—all of which share our development philosophy and advanced manufacturing system. High performance, high quality, and high end in every respect, these lenses give people who love photography lasting value and consistent, exciting results. The secret is our passion for craftsmanship that we put into every production process and every product.

Evaluation with Sigma's own MTF measuring system “A1”

We used to measure lens performance with MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA 50mm F1.4 DG HSM will all be checked using this “A1” before they are shipped.
