THE EVOLUTION OF A CLASSIC
THE 35mm F1.4 ART IS REBORN

Superb optical performance and usability
power up the most popular focal length.
An “Art F1.4 35mm” reborn for mirrorless and empowered through Sigma’s technology to date.

The existing 35mm F1.4 DG HSM | Art was Sigma’s first GLOBAL VISION lens. Released in 2012, it set the standard for all of Sigma’s subsequent Art-line lenses, and thanks to its exceptional image quality it is still the 35mm prime lens of choice for many professional photographers. Nine years on, the 35mm F1.4 has been redesigned from the ground up specifically for mirrorless cameras, and is the culmination of much of the optical design expertise and advanced production techniques gained over the past decade of GLOBAL VISION lens development. As with all of Sigma’s lenses, the 35mm F1.4 DG DN | Art is built entirely at its sole factory in Aizu in Japan, where the standard of craftsmanship is of the highest level.
As is true with all Sigma lenses, class-leading optics are right at the heart of the design concept of this new 35mm F1.4 DG DN | Art. Despite being significantly smaller and lighter than the existing 35mm F1.4, it displays an outstanding level of sharpness right to the edges of the frame at all apertures, as well as exceptionally smooth and attractive bokeh and remarkably well-controlled optical aberrations.
Designed exclusively for use with mirrorless cameras, the 35mm F1.4 DG DN | Art is light enough to feel perfectly balanced on a compact mirrorless camera, yet is packed with an array of professional features including ultra-fast AF, a de-clickable and lockable aperture ring and a customizable AFL button. This gives the lens operability and portability without compromise, making it as ideal for professional projects as it is for casual outings, and as well-suited to video as it is stills.
Sigma is delighted to introduce you to the new gold standard in wide-aperture 35mm primes.

Exceptional optical performance

Central to the design of the 35mm F1.4 DG DN | Art is its sophisticated optical performance, which is consistent with the development of all Art line lenses. The lens incorporates 15 elements in 11 groups. With two Special Low Dispersion (SLD) elements, an Extraordinary Low Dispersion (ELD) element, an ‘F’ Low Dispersion (FLD) element and two aspherical elements, and as well as other high-performance glass, the lens’ advanced optical construction utilizes Sigma’s state-of-the-art optical design technology, minimizing all types of aberration including axial chromatic aberration, which cannot be corrected in-camera.
In spite of having a very wide aperture of F1.4, the lens is able to control sagittal coma flare extremely well even wide open, stopping bright points of light from flaring out near the edges of the frame. This will be particularly appealing to night sky photographers.
Owing to its 11 rounded diaphragm blades, the lens displays smooth, round bokeh so that out-of-focus areas are not distracting. This makes the 35mm F1.4 DG DN | Art well-suited to portraits, supported by its ultra-sharp image quality and minimal color bleeding. It also performs very well in backlit conditions thanks to Sigma’s anti-ghosting and anti-flare technology that it has cultivated through countless simulations and real-life testing in our many years of lens development. This keeps shots high contrast and free of excessive flare even when working in difficult light.

 

Fast and quiet AF in a compact body

The focusing mechanism in the Sigma 35mm F1.4 DG DN | Art features a stepping motor. This motor controls a focusing lens group composed of a single, lightweight element, which means AF is responsive and quiet, and is able to keep track of moving objects very effectively. Manual focusing is smooth and precise, but with the right amount of resistance for filmmakers. Certainly, this lens has a focus mode switch on the body.
The Sigma 35mm F1.4 DG DN | Art wholly embraces the Art line concept, which is “designed with a focus on sophisticated optical performance”. This—paired with its advanced autofocus performance and the convenience of a compact size—makes for a lens that raises the standards.

Professional feature-set

On the body of the Sigma 35mm F1.4 DG DN | Art is an aperture ring that allows aperture to be controlled via the lens, or when set to Auto, using the camera. An aperture lock switch on the lens body allows the aperture ring to be locked in Auto so that it is not accidentally knocked during shooting. A big plus for filmmakers, the aperture ring can be de-clicked, allowing users to seamlessly adjust exposure. Also on the lens barrel is a focus mode switch and an AFL button, which can be customized to a desired function from within the camera menu (depending on the model). The switch is ergonomically positioned to be controlled by the thumb during use.
A petal type lens hood is included in the box, which helps reduce flare and offers the lens added protection if dropped. The hood has a lock mechanism that keeps it attached securely to the lens, and its rubberized grip makes it quick and easy to attach and remove.
On top of this impressive array of features and elegant exterior, the body of the 35mm F1.4 DG DN | Art offers an exceptional level of durability that helps it withstand long-term professional use as well as individual operating parts that give a good fit to the hand. The dust and splash resistant structure* provides sealing on buttons and along joins between constituent parts, and there is a rubber gasket around the mount. There is also a water and oil repellent coating applied to the front element ensures that photographers can rely on it in any conditions.

*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.

*1 When turned ON at the position A, the aperture ring is locked at A. When turned ON at a position other than A, it is locked within the range between the maximum to minimum apertures and will not engage at the position A.
*2 Function available on supported cameras only. Available corrections may vary depending on the camera model.
*3 Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.

DIFFRACTION MTF

GEOMETRICAL MTF

 

 


MTF CHART GUIDE

The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.
* The MTF chart depicts the result at the wide-open aperture.
* For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed.
Inner focus system

To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

 


 

Stepping Motor

The lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF.

 


 

Compatible with Lens Aberration Correction

Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with ‘ON’ or ‘OFF’ in the camera menu, please set all aberration correction functions to ‘ON'(AUTO).

 


 

Super Multi-Layer Coating

Sigma’s own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma’s Super Multi-Layer Coating is highly ef fective, assuring images of outstanding contrast.

 


 

Water and oil repellent coating

Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.

 


 

Aperture ring

Aperture ring, designed to help users work intuitively

 


 

Aperture ring click switch

Mounted with a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.

 


 

Aperture ring lock switch

A ring lock system to prevent from unintended movement of the aperture ring during shooting.

 


 

Focus Mode Switch

Using this switch, it is possible to switch the focus mode between AF and MF.

 


 

Linear focus / Non-linear focus (for L-Mount only)

A focus movement method of interchangeable lenses for mirrorless cameras (DN lens) in relation to the rotational angle of the focus ring during manual focusing.
With “non-linear focus,” the amount of focal point movement varies depending on the focus ring rotational speed.
With linear focus, if the focus ring rotational angle is the same, the amount of focal point movement remains the same regardless of the focus ring rotational speed.

 


 

AFL button

The AFL button can be assigned with various functions widens the range of operations available on the lens.
