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.

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 utilises SIGMA’s state-of-the-art optical design technology. This minimises 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 35mm F1.4 DG DN | Art  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 is particularly important for after-dark photography such as night sky shots.

The barrel of the SIGMA 35mm F1.4 DG DN | Art made with a combination of aluminium and a polymer called Thermally Stable Composite, or TSC  ①. This strong and light polymer has a very similar thermal expansion rate to aluminium, meaning that all parts of the barrel behave in a very similar way as the temperature changes. This ensures the best possible optical precision while keeping the weight of the lens to a minimum.

The lens has an aperture ring ② 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 ④ allows the aperture ring to be locked in Auto so that it’s not accidentally knocked during shooting. A big plus for film-makers, the aperture ring can be de-clicked ③, allowing users to seamlessly adjust exposure. Also on the lens barrel is a focus mode switch ⑤ and an AFL button ⑥, which can be customised 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 ⑦, and its rubberised 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 proof structure provides sealing on buttons and along joins between constituent parts, and there’s a rubber gasket around the mount. There’s also a water and oil repellent coating applied to the front element ensures that photographers can rely on it in any conditions.

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.

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.

All Sigma’s manufacturing – right down to moulds and parts – with a few exceptions, are carried out under a single integrated production system, entirely in Japan. We are now one of the very few manufacturers whose products are solely “made in Japan”. We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of Sigma products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.

As an experienced lens manufacturer that has been creating a diverse range of interchangeable lenses, we have started the innovative chargeable service “Mount Conversion Service”. With this service, the mount of your current SIGMA lenses can be changed to another mount of your choice. It gives a new life to your favourite lenses when you wish to use it on a different camera body.

* This “Mount Conversion Service” is different from a normal repair. In order to apply for the service, please contact your nearest authorized subsidiary/distributor of SIGMA.
