Overview
The Sigma 28-45mm f/1.8 DG DN Art Lens for Leica L mount is a full-frame zoom lens that combines a bright f/1.8 aperture with prime-like optical performance. Covering a wide-to-normal focal range, it allows photographers and videographers to travel light without compromising image quality.
Its optical design minimizes flare, ghosting, and chromatic aberrations through a combination of aspherical and Special Low Dispersion elements. The 11-blade rounded diaphragm produces smooth bokeh while maintaining sharpness across the frame, even when shooting wide open.
Designed for video, the lens features an internal zoom mechanism to keep its length constant, suppress focus breathing, and provide smooth operation on gimbals. High-speed linear autofocus is quiet and precise, and manual focus offers adjustable linear and non-linear modes for intuitive control. Durable coatings and a weather-resistant build make it suitable for challenging conditions.
