Sigma Contemporary 18-50mm f/2.8 DC DN 18-50mm
A constant f/2.8 aperture and a mere 98g weight make this 18-50mm zoom exceptionally portable for Leica L APS-C users, with a stepping motor delivering fast, silent autofocus. The lens doubles as a capable macro tool with a 1:2 maximum magnification and a 122mm minimum focus distance, while three aspherical elements maintain edge-to-edge sharpness. Ideal for travel photographers and run-and-gun videographers needing a lightweight, all-purpose lens that handles close-ups without sacrificing bright aperture flexibility.
