Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E

The Sigma 28-70mm f/2.8 DG DN Contemporary is a compact, lightweight standard zoom lens for Sony E-mount full-frame mirrorless cameras. Offering a constant f/2.8 maximum aperture across the entire zoom range, it is an ideal everyday lens for travel photography, street photography, portrait photography, and video work. Lighter and more compact than comparable 24-70mm f/2.8 lenses, it pairs perfectly with gimbals and run-and-gun setups without sacrificing optical quality.
