The Sigma 35mm f/1.4 DG DN Art Lens is a refined wide-angle prime lens designed for full-frame Leica L-mount mirrorless systems. With an updated optical design, this lens combines advanced technology with a sleek, compact build and a bright f/1.4 aperture. Ideal for low-light environments, the fast aperture provides excellent control over depth of field, enabling beautiful subject isolation with shallow focus effects.

The optical design incorporates two SLD (Special-Low Dispersion) elements, one ELD (Extra-Low Dispersion) element, and one FLD (Low Dispersion) element, along with two aspherical elements and high-refractive index components. This combination significantly reduces chromatic aberrations and distortion, achieving sharp, clear images with minimal optical imperfections. A Super Multi-Layer Coating is applied to the lens elements to suppress flare and ghosting, ensuring enhanced contrast and color accuracy, even in challenging lighting situations.

Designed with versatility in mind, the 35mm f/1.4 Art lens features a tactile physical aperture ring, which can be de-clicked for smooth aperture adjustments, and a dedicated focus mode switch, along with an AFL (Auto Focus Lock) button for intuitive control. The lens employs a stepping motor for fast, quiet autofocus, making it well-suited for both still photography and video work. The 11-blade rounded diaphragm produces a pleasing, soft bokeh.

Weather-sealed to protect against dust and moisture, this lens ensures reliability in demanding conditions. The robust construction includes a brass bayonet mount for precise fitting and durability, making this lens an excellent choice for creative and artistic professionals.
