Description

The 28-45mm f/1.8 DG DN Art is engineered for "prime-standard" optical quality. Its complex design features 18 elements in 15 groups, including five SLD (Special Low Dispersion) and three aspherical elements to rigorously correct aberrations and ensure surgical sharpness even at f/1.8. To maximize contrast in backlit situations, it utilizes Sigma’s Nano Porous Coating alongside a Super Multi-Layer Coating. For filmmakers, this lens is a masterpiece of functionality. It features an internal zoom and focus mechanism, meaning the lens never changes length, keeping your gimbal perfectly balanced. It is designed to virtually eliminate focus breathing, ensuring your compositions remain stable during focus pulls. The autofocus is driven by Sigma's flagship HLA (High-response Linear Actuator) motor, providing near-silent and lightning-fast tracking. The build is professional-grade with a dust and splash-resistant structure, a water/oil-repellent front coating, and dual customizable AFL buttons. It even includes an aperture ring with a de-click switch for silent iris adjustments during video recording.
