A classic wide angle lens updated for full-frame Leica L-mount mirrorless systems, the 35mm f/1.4 DG DN from Sigma is an Art-series prime characterized by its advanced and updated optical design, sleek profile, and bright design. The f/1.4 maximum aperture enables working in low-light conditions and also provides increased control over depth of field for achieving shallow depth of field effects. The optical layout incorporates two SLD Special-Low Dispersion, one ELD Extra-Low Dispersion, and one FLD Low Dispersion elements. It also incorporates two aspherical elements and high refractive index elements to achieve a notable degree of clarity and sharpness with well-controlled distortion and aberrations. Also, a Super Multi-Layer Coating enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions.

Balancing the optics is a refined exterior design, which features a physical aperture ring, which can be de-clicked or locked, along with a dedicated focus mode switch and AFL button for intuitive and tactile control. For autofocus, a stepping motor is used that maintains a lightweight and compact design while promoting fast and near silent focusing performance for both stills and video applications. Additionally, the lens features an 11-blade rounded diaphragm for smooth bokeh quality and the lens housing is also weather-sealed to suit working in inclement conditions.

As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.

Wide-angle lens is designed for full-frame Leica L-mount mirrorless cameras but can also be used with APS-C models where it provides a 52.5mm equivalent focal length.

Bright f/1.4 maximum aperture is particularly well-suited for working in available light conditions and provides extensive control over depth of field for isolating subject matter with selective focus.

Lens Construction: 15 elements in 11 groups, including one FLD low-dispersion element, one ELD extra-low dispersion element, two SLD special-low dispersion elements, and two aspherical elements.

A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. Resistance coating allows oil and water to be easily wiped from the front lens surface and prevents oil and fat from sticking for easy cleaning.

Integrated stepping motor realizes quick and quiet internal autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. Face and eye detection supported in feature enabled cameras.

Manual aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications. Additionally, a dedicated aperture ring lock switch can also be employed to prevent accidental shifting of the aperture setting.

Built-in Autofocus-Lock (AFL) button which can be assigned additional functions widens the range of operations available on the lens.

Rounded eleven-blade diaphragm contributes to a smooth and pleasing bokeh quality.

Weather-resistant construction with a brass bayonet that affords improved mounting accuracy and rigidity.

A: The focusing ring on this lens does not have any distance marking. There is no specific marking on the lens for this. The more one stops down the more appears in focus. But like most lenses, there isn't a point when absolutely everything is in focus.

Q: 4. Has sigma fixed the chromatic aberration for this model?

A: The Sigma 35mm f/1.4 DG DN Art Lens for Sony E does have some chromatic aberration issues, but te lens still gets good reviews.

Q: 5. Can I use this lens with my canon? I have the r6?

A: No. This is only currently available for the Leica L and Sony E mounts.

Q: 6. How is the manual focussing for this lens?

A: Sigma 35mm f/1.4 DG DN Art Lens for Sony E has a physical switch to turn off the lens Integrated stepping motor which allows smooth and internal manual focus. If you wish to focus manually, set the focus mode switch on the lens to the “MF” position. You can adjust the focus by turning the focus ring

Q: 7. Can this lensbe made to work Can this lens be made to work with a Canon DSLR? If not, any plans to make one for a Canon DSLR?

A: No, the Sigma 20mm f/1.4 DG DN Art Lens for Sony E will not work on a Canon DSLR. The Sigma 20mm f/1.4 DG HSM Art Lens for Canon EF will work on Canon DSLR cameras. B&H # SI2014C

Q: 8. How does it compare to the SONY FE 35mm f/1.4 GM from an image quality standpoint?

A: The Sony FE 35mm f/1.4 GM Lens is slightly sharper than the Sigma 35mm f/1.4 DG DN Art Lens for Sony E.

Q: 9. I'm curious about the AF noise for video. I used the HSM version recently and will have to add some sound design over the clicking noise of the motor. Wondering if the DN version is better? Usable? I've heard conflicting reviews.

A: The DG DN lenses were designed with Mirrorless and Video in mind. I tested both this lens and the Sigma 35mm 1.2 DG DN on a Leica SL2S. The lenses aren't making any noise even in the most dramatic focus pulls. You should be fine with either lens for video, although the AF performance varies per camera.
