The Sigma 28-45mm f/1.8 DG DN Art lens represents a breakthrough in mirrorless photography—the world's first full-frame zoom with a constant f/1.8 aperture across its entire range. Engineered with 18 optical elements including three aspherical and five Special Low Dispersion components, it delivers prime-like sharpness and exceptional light-gathering capability. The 11-blade circular aperture produces beautifully rendered bokeh, while advanced coatings eliminate flare and ghosting. Ideal for photographers and videographers seeking professional-grade performance without the weight penalty of multiple prime lenses, this L-mount lens combines versatility with optical excellence that rivals dedicated fixed-focal-length optics.
