An inherently flexible focal length, the Leica L-mount 35mm f/2 DG DN Contemporary Lens from Sigma is a sleek wide-angle prime pairing a bright design with a portable form factor. The standard wide field of view is useful for a broad array of subject types, including landscape, street, and reportage shooting, and the f/2 maximum aperture excels in challenging lighting and enables greater control over depth of field. In terms of the optical design, three aspherical elements and one SLD element are used to minimize a variety of aberrations and distortion for sharp and accurate rendering. Also, a Super Multi-Layer Coating helps to control ghosting and flare for improved color fidelity and contrast.

In regard to handling and focus, this lens features a stepping motor for quick and quiet AF performance that suits both photo and video applications. As an I Series lens, too, this lens features a manual aperture ring and all-metal barrel constriction for enhanced tactility. Additionally, there is a rounded nine-blade diaphragm for smooth bokeh quality and the lens housing is also weather-sealed to suit working in inclement conditions.

Q: 2. Although the Leica T is not mentioned in the compatibility section, can this lens be mounted on a Leica T with autofocus capability?

A: Sigma does not list the Leica T. But the lens is very new and that model is on the older side. Chances are it does work with the T as its L mount. But till it is out and some test it with the T we cannot be 100%

Q: 3. where is this lens made?

A: The Sigma 90mm lens is made in Japan.

Q: 4. Which lens is better for every day use and different genres (including portraits), this one or 45 2.8?

A: I apologize in advance for the vague answer, but "better" will very much depend on the kind of photographs you make and the kind of compositions you enjoy. Typically, 35mm/40mm are seen as more "traditional" for street photography, but the 45mm might offer you tighter, slightly more intimate perspectives during everyday shooting. Truthfully, there isn't a significant difference between them, and you should be able to enjoy making photographs with either! With regards to portraiture, the longer focal length 45 is typically better due to lesser distortion, but depending on your type of portraiture (environmental portraits versus headshot/corporate portraiture), this will also vary the choice of lens.

Q: 5. There's a ring to select aperture on this lens. However, is it still possible to dial the aperture from the aperture wheel on the SL rather than through the aperture ring on the lens?

A: Yes there is a way. Turn the aperture ring to "A" (like it shows in the photo) and you'll have control through the camera instead of the lens.

Q: 6. Is weather sealing same for both L-Mount and Sony Mount?

A: The Sigma 24mm f/2 DG DN Contemporary Lens for Leica L has the exact same build quality as the Sony mount version. Both versions are weather sealed.

Q: 7. What’s the difference between this lens and the Art lens? Does anyone know? Thanks

A: The Art-series of Sigma lenses represents their highest quality offerings, typically also offering larger apertures, with the trade-off being significant increases in size, weight, and price. Contemporary lenses are mostly smaller, high-quality offers with reasonable apertures meant for the budget-conscious consumer that isn't willing to sacrifice too much quality in order to get a great lens. This usually applies across the board, and is especially true for the new DG DN Contemporary lenses which are significantly smaller than their DG Art counterparts.

Q: 8. Can autofocus on this lens be turned on and off from the camera body? Thanks.

A: If the camera you own has the ability to turn the autofocus feature on and off via the camera's menu, then yes, it can be done from either the camera body via the menu or via the AF/MF switch on the lens. When you disable the autofocus either via the camera's menu or directly on the lens, you would enable the fine focus ring function for manual focus usage needs.

Q: 9. Why no data in the Specs page? is this lens weather-proof?

A: This Sigma 24mm f/2 DG DN Contemporary Lens for Leica L, would have a Weather-Sealed Construction.
