Leica UV Filter E49 49mm UVa II - Black

The Leica E49 UVa II sits at the intersection of practical lens protection and brand-consistent optical tooling. Sized at 49mm and carrying the E49 designation, it is built to fit within Leica's own filter nomenclature — a detail that matters to photographers who maintain a Leica-specific kit and prefer components sourced from the same manufacturer as their glass. The UVa II type identifies it as a UV-A absorbing filter, targeting the ultraviolet wavelengths that can register as unwanted haze or reduced contrast in outdoor and open-sky photography. The II suffix indicates this is a second-generation version of Leica's UVa filter, representing a refined formulation rather than the original design.

Glass construction is the material claim that carries the most weight in this filter's designation. In the protective filter market, glass, optical resin, and polycarbonate each occupy different positions on the quality and price spectrum, and a glass filter resists fine surface scratches more durably than softer materials over extended use. The black finish on the filter ring serves a functional role alongside its aesthetic one, reducing stray light reflections within the filter barrel during shooting. Buyers should confirm that their specific Leica lens carries a 49mm front thread before purchasing — Leica's lineup spans multiple filter sizes across different focal lengths and generations, and the E49 designation applies only to 49mm-threaded lenses. The product listing does not include details on anti-reflection coatings or optical transmission specifications.
