The Sigma 45mm f/2.8 DG DN Contemporary is a masterfully crafted prime lens designed specifically for full-frame Leica L-mount mirrorless systems. Striking a perfect balance between high-performance optics and an ultracompact form factor, this lens is part of Sigma’s Global Vision “I Series” philosophy—providing a tactile, premium experience for photographers who value both style and substance. With its natural field of view and exceptional rendering, it is the ideal “always-on” lens for street photography, travel, and environmental portraiture.
Exquisite Rendering & 3D Pop
Unique Optical Character: Unlike many modern lenses that chase clinical sharpness alone, the 45mm f/2.8 is engineered to provide a classic, three-dimensional impression. It renders subjects with remarkable pop while maintaining smooth, creamy bokeh in both the foreground and background.
Optimized for Bokeh: The optical design specifically controls spherical aberrations to ensure that out-of-focus highlights are large, soft, and rounded, avoiding the harsh edges often found in compact primes.
Versatile “Normal” Perspective: The 45mm focal length sits in the “sweet spot” between a 35mm wide-angle and a 50mm standard lens, offering a highly natural view that mimics the human eye. It is also compatible with APS-C models, providing a 68mm equivalent focal length.
Built for the Modern Creator
High-Speed Stepping Motor: Equipped with a sophisticated stepping AF motor, this lens provides fast, precise, and near-silent focusing. It is fully compatible with Face and Eye Detection AF, making it just as capable for high-end video production as it is for still photography.
Tactile Mechanical Design: True to the Contemporary line’s commitment to quality, the lens body features an all-metal construction and a dedicated manual aperture ring for a traditional, mechanical feel.
Close-Up Capability: With a minimum focusing distance of just 9.5 inches, this lens is perfect for tabletop photography, food shots, and intimate details, allowing you to get close while maintaining a beautiful background blur.
Professional Build Quality
Weather-Sealed Brass Mount: The bayonet mount is constructed from solid brass for long-term accuracy and durability. A rubber seal at the mount provides dust- and splash-resistance for shooting in unpredictable weather.
Seven-Blade Rounded Diaphragm: Complemented by a rounded aperture design, the lens produces smooth and pleasing bokeh transitions throughout the aperture range.
