Sigma 28-45mm F1.8 DG DN Zoom Lens
SKU
U68696
Category: Sigma
The Sigma 28‑45mm F1.8 DG DN | Art is a premium wide-to-standard zoom lens for full-frame mirrorless cameras (Sony E‑mount and L‑mount). What makes it special is its constant f/1.8 aperture throughout the zoom range, which is rare for full-frame zooms. Sigma claims this lens delivers optical performance comparable to prime lenses. It’s built with features aimed at both still photography and video: minimized focus breathing, internal zoom (so the lens doesn’t extend when zooming), dust/splash resistance, and coatings to reduce flare and ghosting. It also has useful control features like an aperture ring (with click/de‑click and lock options), custom AFL buttons, and a high-response linear actuator autofocus motor.
