The Laowa 15mm f/2.0 Zero-D lens for Leica M mount is an ultra-wide-angle lens with a bright maximum aperture and an optical design that minimizes distortion. With a field of view of 110 degrees and a compact build weighing approximately 500 grams, this lens is designed for landscape, architecture, and astrophotography. The f/2.0 aperture allows for effective performance in low light while maintaining straight lines and minimal chromatic aberration. The optical construction includes aspherical elements that contribute to the nearly zero distortion characteristics and controlled flare performance. The lens offers a minimum focusing distance of 15 centimeters, enabling close-up shots with shallow depth of field. Filter compatibility is provided by a 72-millimeter filter thread integrated into the lens hood design. Manual focusing is standard, but compatibility with M-E and M-Z autofocus adapters allows autofocus functionality for Sony E mount camera systems. The lens features Leica 6-bit coding capability for camera recognition and EXIF data recording. The physical dimensions and weight distribution make this lens suitable for longer handheld photography sessions while maintaining optical precision throughout the entire aperture range.
