Sigma 28–45mm F1.8 DG DN | Art (L-mount)

The Sigma 28-45mm F1.8 DG DN | Art is a groundbreaking lens that defies conventional optical limits. It is the first zoom lens for full-frame mirrorless systems to deliver a constant F1.8 maximum aperture, providing the light-gathering power and exquisite bokeh of a prime lens with the versatility of a zoom. Engineered for elite photographers and filmmakers, this lens delivers edge-to-edge sharpness and clarity that rivals the finest fixed-focal-length optics in the Sigma Art lineup.

• Unprecedented F1.8 Brightness: Enjoy the creative freedom of a fast F1.8 aperture across the entire 28-45mm range. Perfect for handheld shooting in low light and creating cinematic shallow depth-of-field.
• Inner Zoom Mechanism: The lens maintains a constant physical length regardless of focal distance. This internal movement ensures maximum stability on gimbals and tripods, while enhancing resistance to dust and moisture.
• Prime-Level Performance: With 5 SLD and 3 aspherical elements, aberrations are meticulously corrected. Advanced Nano Porous and Super Multi-Layer Coatings ensure high-contrast results even in difficult backlighting.
• High-Speed HLA Autofocus: Driven by a High-response Linear Actuator (HLA), the autofocus is incredibly fast, precise, and near-silent—essential for both high-speed stills and professional video production.
• Cine-Ready Ergonomics: Features a de-clickable aperture ring, suppressed focus breathing for natural focus pulls, and two customizable AFL buttons for seamless operation in any orientation.
• Consistent Close Focusing: A constant minimum focus distance of 30cm across the zoom range allows for stunning close-up shots with a 1:4 magnification ratio at the telephoto end.
