Sigma Art 28-45mm f/1.8 DG DN 28-45mm
A constant f/1.8 aperture across its 28-45mm zoom range rivals prime sharpness, using 3 aspherical and 5 ED elements with Nano Porous Coating to suppress flare. Weather-sealed construction pairs with a fast, near-silent HLA autofocus motor and an inner zoom mechanism that avoids balance shifts on gimbals. Best for portrait photographers and hybrid shooters who need f/1.8 brightness across a flexible field of view without swapping lenses.
