Why This Lens Stands Out:
The Sigma 28-45mm f/1.8 DG DN Art represents a revolutionary breakthrough in zoom lens technology. Its constant f/1.8 aperture throughout the zoom range provides unprecedented low-light performance and creative control. The internal zoom design maintains a consistent length, making it perfectly balanced for gimbal work, while the advanced optical design delivers image quality that rivals prime lenses. With a minimum focusing distance of just 11.9" across the entire zoom range, this lens offers incredible versatility in tight shooting situations.
